OS X :: Unable To Boot From CD Drive?
Aug 3, 2010
I ran the Boot Camp Assistant to partition my hard drive, and it successfully created the "BOOTCAMP" drive. When it asked for my installation CD, I tried loading a Windows 7 installation partition through a USB hard drive, but the assistant would not recognize it as an install disk. So, I closed out of the assistant early, leaving the Boot Camp partition in place but Windows non-installed. Eventually, I rebooted my machine in an attempt to boot directly from the USB drive and resume installation.
However, I found the machine will not boot at all. It powers on normally, makes the startup sound, but after a few seconds I'm left with just a flashing folder and question mark icon. Holding down Option-key at startup does nothing. Trying to boot from my Snow Leopard disc by holding down C or D during startup does nothing. Holding down Command-S does nothing. Holding down Shift-key does nothing. Resetting the PRAM does nothing. I have also tried booting from a Windows 7 install DVD -- the drive spends an extra 20 seconds or so scanning the disk, but then skips directly to the flashing question mark.
What can I do? Is there some way I can access the EFI to make sure the correct startup disk is selected? Why am I unable to boot from my CD drive?

I have a 2TB Hitachi Backup drive, and a 1TB Verbatim Portable drive, both are USB 3, and when they are connected and the iMac is switched off, it will not boot until I remove the drive.
How can I leave the 2TB drive connected and power up the iMac ?
The 2TB drive was purchased to be a Time Machine backup drive.

iMac, Mac OS X (10.7.3), 3.4GHz Intel Core i7 - 8GB

Two years ago I installed Leopard on a pair of striped Fantom Hard Drives (3TBs) via Firewire 800, and have been running my 2007 Macbook Pro off it ever since. When Snow Leopard came out, I updated it with no problems. When Lion came out, again no problems. Last month I bought a CalDigit VR2 with dual hard drives (4TBs) specifically built for running OS externally. But no matter how I configure, install, or connect... it will not boot up my Macbook Pro, or my Macbook Air.
Last week I bought a new Fantom external hard drive (1.5TBs) and discovered the same exact issue, with one exception... the Fantom will boot the Macbook Pro via USB 2.0, but only when plugged into the left side port.
Has anyone else noticed this change?
P.S. I've talked to the people at CalDigit, Fantom, and Apple, and no one seems to have an answer.

I've been hearing good things about the Spinpoint Drives and the 750GB ones are coming down in price.Here is my current setup1 - 500MB Drive - Leopard2 - 320MB Drive - Vista 643 - 500MB Drive - FAT32 (Shared, Irrelevant)I plan on replacing drives 1 and 2 with 750GB Spinpoint drives.My question is, can I boot off of the Leopard dvd and put in Drive 1 and NewDrive1 and just clone it, and do the same for Drive2 and NewDrive2 and clone it? And then go into Leopard and resize the HFS partition, and go into Vista and resize the NTFS partition?

I am considering purchasing diskwarrior but want to make sure it can help my situation before I purchase it. My imac will not boot from the internal hard drive (Intel processor) When I use disk utility to try and repair the disk, I get error messages and it won't repair. I can see the HD but cannot repair it. When I connect using target mode with my mac book pro, the hard drive does not appear on my host (macbook pro) computer. I have reloaded OS X (Leopard) onto a firewire external drive and can boot my imac that way but I can not find my original internal Macintosh HD. Will disk warrior be able to help with this scenario. I would really like to access that internal Macintosh HD and retrieve my files.

Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

So I installed osx 10.4 server on a Power Mac G4 (white/blue)
Went throught the setup screens and did a complete reformat / install.
Just boots to the loader screen. (Where the mac face shows, followed by a question mark) and just cycles over and over.
I can put the DVD in at this point and restart the install.. I did go in and check the disk permissions and disk status and both passed.

If I have iTunes on an SSD drive (the boot drive in my Mac Mini), can it read the music library on a second rotational hard drive? I'd like not to have the large music library on a 120GB SSD drive.

This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there. However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.

I decided that I couldn't wait for Gainestown and ordered a 2.8x8 MP today. I'm going to get another 8GB of RAM (I assume 10GB in matched pairs will still perform at full speed). My real dilemma is a Boot/Storage solution-I'm moving from a Dual 867 G4, so all my current drives, both internal and external are IDE, which basically means I'm starting over as far as internal drives goes. The G4 power supply gave out so I'm getting this external enclosure to put my old drives into for file recovery. As far as new drives go, I can't figure out what to do. I'll spare you my million iterations of drive configs I've sketched over the past two days.

I run SSD/HDD, my HDD in the optibay is broken, I stuck it in a external and it makes finder freeze, it got bumped around too much so I want to put a new one back in the 'correct place' for a spinner, and stick the SSD in the optibay.(I figure the extra 2% of shock protection offered by the orange rubber circle things is worth the trouble of moving everything).
I am also going to buy a WD 3 platter 1TB laptop drive, and I read that they fit fine in the regular spot in MBP's (I'm going to open and measure in a min.)Anyways, there's no BIOS, only EFI, so how to I pick what drive to boot from? with 10.6 is it as simple as holding option down on boot, and picking my 'OSX' HDD, and then it will auto boot from that until I specify otherwise? (I ask because before 10.6 people on here were always talking about how to switch boot drives.)

In my attempt to install Windows XP via Boot Camp, I accidentally inserted an SP1 disc instead of the SP2 disc that I have. The installation proceeded to the point where it does for most who attempt this: the screen where you are prompted to press ENTER. I could not proceed and therefore restarted the iMac and held down the mouse button upon start-up to remove the CD.
HERE IS THE PROBLEM:I can not boot into OS X because the keyboard shortcuts (those that might allow me to select which partition to boot from and/or reset PRAM) seem to be disabled. Instead, a reboot always ends at a black screen with a blinking DOS-esque cursor, or the prompt: "No bootable device -- insert boot disk and press any key."
I have attempted inserting my SP2 disc at this point, to no avail. My keyboard seems to be disabled, as if the SP1 install proceeded just enough to establish itself as the boot drive without drivers for the keyboard. I've tried using all 3 USB ports, disconnecting other USB devices. Oddly, my bluetooth mouse works to eject the CD on reboot...

After my macbook hard drive kindly failed on me, I ordered a new Seagate Momentus 5400.5, 320gb hard drive. I popped that sucker in this afternoon and began to start up my macbook with the OS X disc 1. Everything was going smoothly, except that it can't find the hard drive. It is recognized under my disk utility, but when I click to partition it, select options, select GUID, click 'OK', I can neither Name it 'Macintosh HD' or do anything else.
I can't proceed with anything because when it asks me to select a HD, the HD does not show up. Again, everything works except that the hard drive is not found. I pulled the hard drive out. Made sure the screws were alright. Made sure everything was all snuggly, and yet it still won't work.

My friend gave me his old Apple cube G4 + 15" Cinema display in like 1000 pieces. Its completely teared apart. I tried a lot, but it doesn't work. The original IDE cable wasn't included, so I bought one for 2 cents. It should work or not? Maybe the powersupply. I'm not sure. I don't believe actually that the hardware itself, like the motherboard is broken. When everything is into place and I connect the cube to the powersupply it boots immediately. I don't have to do anything. Harddrive spins and the superdrive makes some noise as well. This repeats itself every 5 seconds. The screen is connected and gets power through DVI, but no display. Both the cube and display have touch enabled buttons to switch it on, but they do not respond (I guess).. Motherboard gives 2 light. DS1 is green, DS2 is red.

I have two WD 640gigs and the stock WD 500, and I am having trouble deciding on the the optimum configuration. I am open to suggestions. I use my computer for general use as well as for my video editing and graphic design hobbies if that info helps.
I am curious as to the benefits of of the following:
Drive 1 (640)
partition 1: 150gig for OS
partition 2: Bootcamp
remainder: Offline storage
Drive 2 (640)
partition 1: Applications
remainder: music/photos
(scratch disk here?)
Drive 3: (500)
Time machine
Would there be a noticeable benefit to having the applications being separate from the OS boot drive? What if anything else should be split across multiple HDs to increase speed? I've heard of moving the swap file from elsewhere on the forum but I am not sure as to what exactly that is nor the benefits of doing it.
My final question(s) is how exactly I could go by moving my application folder to another drive separate from the OS drive? Just drag and drop? What is this deal with making an alias?

My internal 1TB hard drive on my iMac is dead and I don't have the money to replace it at the moment. I have everything backed up on an external 1TB drive using Time Machine. As a workaround for the time being,Is there any way I can install the system on the external drive and use that as the boot drive without erasing the Time Machine Backups? It seems to me I would have to have two partitions for the external drive, one for the system, and one for Time Machine. But is there any way to add a partition without erasing the existing one with Time Machine only on it?

I have a brand new MBP. I have a 1tb external drive with 250gb's of music. I have it attached to my mac via USB. I CANNOT GET ITUNES TO CREATE A NEW LIBRARY ON THE EXTERNAL DRIVE. I CANNOT DRAG AND DROP OR ADD FILE/FOLDER.
But get this, I hook it up to my old Dell and I can do whatever I want. I am friggin pissed that I spent all this money on Mac equip and can't get it going. You may have seen my other post where I posed my issue of: 1tb ethernet drive hooked to airport extreme. Above mentioned 1tb hooked up to back of it via usb. I am completely unable to copy, move, or add files using my mac. But guess what. my pc handles it easily and quickly.

When I travel I would generally take a small travel drive that is clone of my white MacBook as a rescue drive.Now that I have the MBA I am wondering if I could just clone my 11.6 MBA to a 64 GB flash drive and then if the worst happened I could reverse clone from the flash drive to the MBA.

Here's another speculative question for if/when I get a Mac Pro:I don't forsee myself needing the multiple terrabytes of storage most of you guys seem to have , since I'm still doing OK with just the stock 250GB that came with my G5 Quad + an external 120GB. I'll probably get a 750GB drive for boot, apps, and most files (leaning toward SpinPoint F1 750; the new 640GB WD also seems enticing).So, here's my Q: which would be a better setup for apps like Photoshop as well as the OS (I've read you can relocate the swap file?), performance-wise (both in terms of app speed, and keeping the OS from hanging on a busy disk) - using the slow stock 320GB as a more dedicated scratch disk (possibly just a partition on it, with other partitions for Windows), or using the free space on the faster, but non-dedicated, boot and storage disk?

I have a relatively new Mac Pro with a 320gb sata system drive. I'm giving some thought to getting a SSD and making it my system drive for booting and applications (including Photoshop CS4), and using the 320gb drive to store photos and videos.

I'm having an odd problem that I can't figure out. I have a fairly new iMac (the aluminum one). It originally had Tiger on it, then Leopard came out 1 week later. I upgraded to Leopard once it came out. I then purchased the Snow Leopard upgrade, and upgraded my iMac to SL.
I've been running SL great on it for several weeks now (since SL was released). I haven't had any issues, except with Time Machine. I wanted to do a verify/repair disk on the HD, so I attempted to boot my iMac from DVD.
It did not boot automatically to DVD, so I attempted a "C" during startup to boot from my DVD. After about 5-10 mins of waiting, it dropped me into "Safe Boot". I can not seem to boot it from the DVD.
I rebooted my iMac, and double clicked the install icon from the DVD. It's giving me the following error:
"Mac OS X 10.6 cannot be installed on this machine"
It's claiming that I need v10.5 or higher to install. I'm currently at 10.6.1, so I'm not sure what it's complaining about.
Has anyone had or seen this issue before? All I'm trying to do, is perform a repair disk on my HD...but I can't even boot from my DVD anymore.

I'm still working out the details on purchasing a new MacPro. My Apple sales rep tells me that I can greatly increase the launch speed of applications and the system OS by purchasing 2 hard drives and using Disk Utility to stripe them together into a "software RAID". They claim it will be faster and more reliable than a single SSD. I know I've asked this question before, but the answers were over my head. I don't know anything about SATA raid cards, or SSD's except for their benefits. But I'm pretty sure I can stripe two drives together and make a software RAID.

So I have been running into a bunch of weird issues lately (got errors on emptying the trash, FCP is acting all crashy, couldn't unmount an internal disk to format it, etc) so I wanted to run the hardware test that is on the installer disk that came with my MP. Problem is, the machine won't boot from the disk. If I boot holding down the D key it boots to a grey screen and a dialog box pops up for a second and then *poof* the computer shuts down. It happens so quick there is literally no chance to read what it says. If I boot holding down option and try to click the install disk I immediately hang, the mouse doesn't respond anymore and I'm screwed and need to hard restart.
So I figured "hey I got a backup, I'll just reinstall OS X". Nope, still won't boot using the "install Mac OS X" from the disk. I click restart and I just get a grey screen again and nothing happens. I hear the drive spin up and then spin down and silence. Everything is disconnected from the computer except for my screen my keyboard and mouse.
Everything is up to date. Zapped pram, repaired permission and ran cron scripts via Onyx so I am at a loss what to do now. This is troubling because even if I have a problem I have no way of reinstalling the OS. I can work because the computer is working almost normally but this worries me.
This is a new MP 2.8.
Everything has been working tip top until this morning.
EDIT - I bought SL for my MBP so I have the retail disk. I was able to boot from that but it doesn't have the hardware test so it still looks like I am SOL for now.

We've got a MacBook that's not booting. It gives a question mark when we turn it on.
I've tried resetting the PRAM and SMC, to no avail.
I've tried booting holding Option to list all bootable volumes, and nothing is listed unless I put the install DVD in.
I've booted from the restore disks, and tried to reimage the MacBook, but no volumes showed up to install to.
I tried Disk Utility off the install DVD, and it listed no bootable volumes.
I tried System Profiler off the install DVD, and it said "There was an error while scanning for Serial-ATA devices."
Is this absolutely for sure a hardware issue? this guy seems to have solved almost the same problem without, but I'm not able to reinstall like he did (it gives me no volumes to install to).
I don't have much time and need to know whether to send it in to Apple or not. Being that we're past 90 days, they won't give us tech support over the phone, so if it's not a hardware problem, we're going to get charged, and other circumstances dictate that the computer either be fixed or installed ASAP.

I have mac os x version 10.5.7 running on a macbook pro 2.4GHz Intel Core 2 Duo. And my boot camp version is 2.0.
I installed windows vista via boot camp, then uninstalled it following the procedures in the boot camp help file. However after uninstalling windows, whenever I start my laptop it is unable to boot into mac automatically. And after a while shows a screen showing an error that it could not find a bootable drive. So I have to manually press alt(option) button and select the Mac drive to boot into mac os. There is no other os installed than mac.

Whenever I turn on my computer, I see a flashing folder icon, occasionally interspaced with a globe icon. I read elsewhere that this lasts for several minutes, but it can go on for an hour without pause. I tried booting up from my install disc, but couldn't get the computer to acknowledge it.
I was able to start installing with a 10.5 upgrade disc, but was unable to complete it because the computer did not already have 10.4 or later on the HD (for the record, I was on 10.5.8 before it crashed). I tried restarting it from the Network.
I can't even access my HD through a firewire cable; the HD simply won't show up on the host computer's screen. I'm pretty sure this means that my HD is hosed, but I thought I'd ask to make sure.

I was using my MacBook pro, it required an update, when the update was finished and it went to restart. It began to restart like normal, the chime went, the fan startedup, it went to the grey screen with the apple, the wheel started turning but that's as far as it gets. It won't go further then this screen, the wheel just keeps spinning.

I have a new MacMini without the optiocal drive. This is a computer that someone tried to put Linux on and left it was a 100gb partition for the MacOS and the rest for the Linux installation. I want to get it back to one large partition.
I know that I need to get the computer to boot from something else because the Recovery partition is on the HDD. To that end I have tried to boot this from an external USB DVD-RW drive and when it starts to boot from the disk it reads the DVD and then goes to the 'circle/slash' screen. I then made a USB drive bootable and restored the dmg file for my Lion disk to it and tried to boot from that. It shows in the options and then immediately goes to the 'circle/slash' screen. I tried to flash the PRAM and got the same result. I tested both items on another MacMini and they work. The test computer was a previous model with the optical drive.
