OS X :: Unable To Boot From Disk
Sep 23, 2010
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.

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.

I've created a Snow Leopard boot disk using this method link. I created it on a 16GB CF Disk. I've tried it twice. First time I formatted the disk as eXfat with 1 partition. Next time I used Mac OS Extended for a 7Gig partition and fat32 for the rest.
Upon boot I get the normal install stuff like I do with the DVD, but then no hard disk shows up. I thought it was because of the eXfat which is why I tried again. I looked into the system profiler and I can see my seagate hard disk, but under disk utility it doesn't exist. My Sata DVD drive shows up though. If I boot off of the DVD I can see and install to my hard disk.
I'm trying to make a USB Disk because I'm planning on getting a SSD and I will be removing the Dvd drive.
This is a Mid 2009 Macbook.

i would like to reserve my 4th bay for windows only drive and a software raid will be used for these.
what would you think is a better set-up,
3x internal drives (all of the same model, probably WD 640's) set in raid 0 (both serve as boot drive and scratch disk) occupying bays 1, 2, and 3. In this set-up, everything (DVD's, music, photos, final cut media) would be stored on this array.

My problem is that when I try to boot to the XP installation disk, I get the very fast, flashing, gray apple, followed by a question mark folder, followed by the ghostbuster symbol, without the ghost.
The disc keeps spinning, but the windows installation screen never appears.
I'm new to installing windows with boot camp.
Anybody know what I'm doing wrong?

My Macbook is starting to get really slow. I've tried Onyx and it told me that the startup volume had to be fixed. But I can't boot my install DVD by pressing "C" in the startup.
Is there another way to repair the disk?

I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.
I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc".
I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.
Info:
MacBook, Mac OS X (10.5.6)

I'm currently in the process of trying to install Win7 on my Macbook Pro (purchased July '07) using an ISO burned to a DVD with Disk Utility. Unfortunately, the DVD isn't bootable, and while the symptoms match what's in this blog post, the author's solution involved using a Windows-only program.
I'd like to know if it's possible to re-burn the ISO without the version number in the filenames as in the original solution, but with Disk Utility or something else that a Mac can use.

Just an FYI. Tech Support at Allsoft states The Disk Warrior 4.2 Boot DVD will not Boot the new 2010 MBP's. They are waiting for information (software) from Apple.
Will need to use Target Mode or another Mac connected with Firewire till then. Boot from that then run DW from your MBP.

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.

Yesterday I switched on my macbook (Leopard) and got the flashing question mark. Ran all the resets and booted with disk utility which encountered an 'Invalid B-tree Node' when attempting to repair the disk. Additionally, the SMART status was verified.
I ran DW 4 last night, and performed the hardware tests which reported that the disk was operating like normal. The majority of my media files and additional work is backed up to my Time Capsule but I still have a folder of papers that are relatively new, and wanted to retrieve. While DW managed to reconstruct the majority of my drive (there seemed to be 15g missing - but it's just music files) including this folder, it couldn't replace the disk, as it encountered 'Serious Disk Malfunctions'.
So, via the Disk Preview I want to transfer my saved folders to my TC, but I don't appear to be able to locate it (via ethernet) through DW - even if it's connected when I boot up in DW. So, first request is: Can I connect to my TC to transfer across in DW's preview?
Second is: What are my options if DW can't replace? Do I need to take it into Apple and get a new HD (it's out of warranty)? It's possibly worth noting that I'm a student and have absolutely no money - so cost effective options are a bonus!

Running Diks Util on my iMac 10.6.2. i am given this warning.
=========
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.
Is it something I should heed and what to do in that case?

I've download a Seagate Diagnostics programme to check whether my external Seagate FreeAgent Desk is working properly or not. However, when I run the programme, it indicates that cannot find the disk.

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.

I have tried zapping the pram, nvram, unable to boot from a disk, tried safe mode, tried verbose, did the single user /sbin/fsck -fy several times and it came back with everything appears OK. Tried the hardware test & no trouble found, did the short & long test.The MacBook is a college kid (friend of my youngest) that dropped it off last night and I am stumped. I thought it was surely the HD but all the test say it is fine.I cannot get it to boot from a disk either.

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...

So I restarted, hit option until "Macintosh HD" showed up. Then I hit "c" and "Mac OS X Install Disc" showed up. So far so good.
I then selected the CD, and hit enter. It started to boot up and my cd drive started to make whirring noises, so I knew it was all good. And then, it went into the grey screen with the Apple logo in the middle. However, with it taking a long time, I went for my usual jog (it was my jogging time anyways). But when I came back (over an hour later) it was still on the grey screen with the apple logo.

I have an 08 mac dual quad and wanted to ask if i could boot my computer from an external instead of having the disc as an internal?
that way i can use the 4 bays for terra byte action and run a raid of sorts without having one bay for the OS.
also if i can do this could i also install boot camp on another external to run my boot camp partition from an external as well?
or can you run parallels or fusion from the same disc as the mac OS at the same time?

I have a Mac Pro in which i installed a 300 gig velociraptor along with the stock 320 gig HD. It would obviously make more sense to use this Velociraptor as the boot disk, so how would I transfer the info from the 320 gig hard drive to the velociraptor and change it to be the boot disk?

Today I accidentally turned off my iMac by mistake (pressed off button twice while in sleep mode). And when I try to boot it when it comes to the little mac logo it says "this boot up disk does not work with this mac please restart I press restart and it says the same thing, also when it turned off with an os 9 in it and when I booted it I definatly did not press down c. I think it maybe the hd or is it possible to change boot priority?

Ok, my WD Raptor is both getting too small, and too slow (long in the teeth) so I sunk down for 2xVelociraptors to use for my boot in RAID 0..
I know how to add drives and do RAID in terms of adding drives for storage, but how can I migrate my OS X, Applications, and Preferences to a new boot drive, much less a RAID 0?
do I need to first install the disks into my case and format them for RAID 0, then install OS X as a boot disk on them, the lastly copy over my Applications folder, Library and Users folder?

I wrote a disk image of Tiger I acquired legally! to CD-R (I got a DVD with the CD disk images on it from a friend who has them) using MacDrive on my PC as the disk drive I put in my eMac does not have burning enabled for w/e reason. So, yes, I put the CD-R into my eMac, it shows up on the desktop and it then asks me to restart my Mac to continue with installation, on boot it gets to the Apple, the disk drive ejects and it boots into Panther.

Right now I am booted into the GParted live cd, and I am wondering if my computer will even be able to boot into the OS X install disc if I delete every single partition on my HDD. I am going through a roundabout way of removing ubuntu. Will I be able to boot into the OS X install disc and do an install if I delete every single partition, and leave my HDD completely blank and unformatted?

I am running Leopard on a 1st gen macbook. I used boot camp assistant to partition the disk, and then went to install windows. I didn't back up bc I am an ass. Then I got to the part where I had to choose a partition. I reformatted the Boot Camp partition to NTFS. I then realized that the partition is too small. I have to get back into Leopard to fix the partition problem. Now, I can't reboot to Leopard. Holding alt or the apple key or both does not prevent the windows dvd from booting. When I eject the DVD, it tells me "no bootable disk." I never installed Vista. I don't understand how I could have overwritten anything or caused any data loss.

I keep getting this error..."The disk cannot be partitioned because some files cannot be moved. Back up disk use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."So I've checked and my HD is already a Mac OS Extended (Journaled) volume. I've gone to Disk Utility and verified the HD, verified permissions, and repaired permissions. I don't know what else to do. I don't want to backup the entire drive and format it.

I have a cramped windows partition on my hard drive which is now full, I'd love to reclaim the space by moving it to my Firewire hard drive which has much more available to dedicate to Windows. I used the "Restore" feature of Disk Utility creating an identical copy but when I restarted my computer to boot from it there was no choice of a firewire drive. I checked in the Startup Disk pref pane it wasn't to be seen, and that didn't even show the current Windows partition that was an option when I restarted. When I get info on the volumes in disk utility it says EXACTLY the same thing about each. So needless to say, I'm slightly annoyed but somehow I think I'm trying to get it to work in a way that it can't.
