Hardware :: Can't Boot From External System
Sep 6, 2009
I have a G5, 1.8Ghz computer with OS 10.5.8 installed. Some problems developed and I tried to run Disk Warrior. The disk shows up on the desktop. but won't start when I select either the "C" key or use the option key. The same thing happens when I use an external drive that has the startup drive cloned several months ago. When I use the Option key only the original startup volume appears. When I use the "C" for Disk Warrior the the system folder appears and switches with a Question mark. Again when I try to boot from the OS 10.5 install disk, I have the flashing folder when I hold the "C" down. The same problem I had with Disk Warrior.

I'm selling my old Powerbook G4. Before I let it go, I want to wipe the hard drive and reinstall OS 10.4. I also would like to run disk first aid because I suspect there may be some corruption. The problem: I still have the original system install DVDs that came with the laptop, but the DVD drive no longer works. It just spins the disks for a bit then spits them back out. I do have an external USB hard drive with plenty of free space. Is there a way I can copy the install DVDs (there's a Disc 1 and Disc 2) to the external hard drive, then boot from that drive and treat it like I'm installing from the DVDs? I also have my new MacBook Pro with a working DVD drive. Can I make my Powerbook boot from a CD in the MacBook's drive? If not, how else can I wipe my system and reinstall the OS without a working DVD drive?

I've been reading this site for a while now, first time I'm posting. I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.
Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

I have done some research on triple boot systems, and it appears that a third OS must be run virtually, but all the information I came across was a few years old. Microsoft is running a deal right now on Windows 7 for students so I would like to pick up a copy and try it out.
Is it possible to run 3 operating systems through Boot Camp 3.0? I am not interested in running a virtual OS.
Current Setup:
13" macbook pro
Snow Leopard and Windows XP through Boot Camp

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.

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.

G5 Dual 2GHz

Is it possible to boot from an external Firewire DVD Drive? It certainly isnt from an external USB DVD. Real answers only please, not "I think so" ones based on HDDs or rumours you may have heard!...
Background:
I've got an MCE Optibay in my Mid-2010 i7 MBP. When installing Bootcamp it refuses to install from the external USB DVD drive. In the end I pulled the 2nd HDD out and reconnected the internal DVD. It then worked fine without a hitch. Then I reinstalled the 2nd HDD and all was fine for a few days.
Now I want to resize my Win7 partition (bigger, as MS Visual Studio's bigger than I thought, and I might stick some games on). I can shrink the OSX partition fine with Disk Utility, but windows won't grow the Win7 one because the empty space is before the Win7 partition, not after it. Apparently this can be done with GParted. Guess what? I can't boot the Linux based GParted CDROM from the external USB DVD drive! So, will a Firewire one work where USB fails, and solve my alternative OS booting issues? If I buy one I can then either use GParted, or delete the Win7 partition and start again without having to pull the laptop to bits all over again, only to put it back once I'm done, and possibly have the same issues in the future. Obviously I don't want to blow extra money getting a Firewire DVD drive though if it's a waste of money...

For future reference: what is the best way to get open the CD tray (if installer disc needs to be put in) if your system won't boot? I thought I would ask in case this situation arises. I'm not using a Mac keyboard and there is no eject button on my keyboard. It's a G4 with mirrored doors but I don't see any buttons to eject the tray.

I have a Mac Pro 2008. I just got my second Crucial 256 gig SSD. Wanna make it a Raid 0 with my first one. Here are my thoughts.
Process 1:
1. Use disk utility to restore image of original Crucial 256 SSD to external USB drive
2. Boot up with SL DVD
3. Build Raid 0 using two drives. (do I need to 0 out?)
4. Restore image to Raid 0
5. Boot
Process 2:
1. Boot off DVD
2. Create Raid0
3. Use SL to restore backup from time Machine to Raid 0
4. Boot

I have been over so many settings in system preferences its making my head spin. Every time I boot my macbook that is running snow leopard it makes me log in. This is a very recent thing and I honestly didn't do anything to make it happen. When the problem first started happening it would also have the spinning thing on the bottom of the screen for about 5 seconds at the blue screen when shutting down. It doesn't do that as of lately though. If anyone knows how to stop it from making me log in every time I boot let me know. I will be checking back so if anyone wants to use ichat to log onto my computer to check settings let me know.

I have a Mac Pro, Intel quad core, with several HDs, 2 of which are bootable. One runs Mac OSX 10.4.9 (and houses Pro Tools HD 7.4) and the other runs 10.5.8 (with Pro Tools HD 8.0.2). The Tiger disk is absolutely fine but the Leopard disk will not boot from a stand-still. It can be booted from Startup Disk in System Preferences but if it was the last drive in use then trying boot from off results in a permanent hang on the grey screen. A workaround is holding ALT on startup and choose the Tiger disk but this shouldn't be happening so has anyone experienced this and solved it? I'm trying to avoid a full re-instal but that is an option.

My early-2010 i7 MBP keeps freezing within minutes of boot. I just tried booting in safe mode, and it just froze for the 6th time in 24hrs (like the 4th in a row). I've never performed a time machine backup with this computer (I got it about a month ago), so a full restore would be an absolute last ditch option. Like I said, this keeps happening within a minute of boot. The screen is on, but everything completely locks up. The cursor can't be moved, keyboard doesn't do anything, etc. I have to keep forcing it to shut off w/ the power button.

This machine WILL NOT ALLOW an Install Boot from ANYTHING other than the Jaguar CD. Screen "blinks" when I attempt to use Sys Pref to designate the 10.4 DVD ... Holding down "C" key is a waste, PRAM & NVRAM have been attempted. Re-installing the 10.2 OS still has the SAME RESULT: Machine refuses ANY Sys Pref Startup OTHER than 10.2 ... PERIOD ... Just get a "blink" on the display, no Error Msg, just a blink .I've erased, zeroed & formatted the 80GB HD, matching RAM (4 X 256MB) ... so I'm pretty sure I need to get this "Firmware" thing resolved so the logic board stops being ILLOGICAL ... or ... is it IMPOSSIBLE to go from 10.2 direct to 10.4? Again, Machine info is;400 MHz PPC G4 Silver 1 MB RAM, with a CLEAN 80GB HD As far as OTHER Posts have indicated, I need to download & run the 4.1.7 firmware ... it is VERY DIFFICULT to find ANYWHERE that is governed by Cupertino ...
Info:
Power Mac G4 (PCI Graphics), Mac OS X (10.3.x), Frankenstein Assembled Machine ...

I have downloaded Lion OS 10.7.XX trhough App Store. When I tried re installing the OS it failed after the bootup due to the Hard drive error. Now it is recommending me to format the Harddrive then re install the OS. I'd like to go back to my previous us so that I back up my data prior to formatting the hard drive. How can I boot from my previos operating system that was installed on the device?

MacBook Pro, Mac OS X (10.7.3)

My HDD is split to 3 partitions at the moment:
-Mac OS X (primary, OS does not boot)
-Storage (formatted for Mac)
-Windows (NTFS)
Is it possible to reinstall Mac OS X without formatting storage nor Windows partitions?

I was doing some cleanup on my macbook pro, deleting old log files and suddenly the system froze. I turned off and then on the laptop and to my surprise, the Mac partition doesn't show up on bootcamp menu, and I'm taken directly to Windows.I tried booting from the install disk and repairing the disk with Disk Utility, and although all my data seems to be all right (I can see all of it from Windows), and Disk Utility did not find any errors, when I reboot (while holding the option key) only Windows shows up.

I am upgrading my hard drive in my MacBook Pro and before removing the old hard drive I backed my time machine up to a NAS (Network Hard Drive). I put in the new drive and booted from the Snow Leopard DVD. I formatted it for HFS+ and then selected the option to Restore System from Full Backup. I selected my network hard drive and all seemed to go well. After clicking restart, the machine restarted, gave me the chime, and then displayed the infamous multi-language kernel panic message with some text in the background. Here's a paraphrase of the background text:
"panic (cpu 0 caller) version mis-match between Kernel and CPU PM @/SourceCache/xnu/xnu-1504.9.17/osfmk/i386/pmCPU.c:707
Backtrace CPU 0,... 4 potential args on stack

I just got my first Mac computer (yay), but as I always do with new operating systems, I have already run into a few problems. I tried to use Boot Camp to install Windows XP, and it all went through, but after the installation somehow the XP system was deleted and now I have 2 Mac OS 10 partitions.Um, I'm sorta lost at this point. Since I just got my Macbook Pro today, I don't have any files on it except for 24 music files. I am currently reinstalling the operating system onto the Macintosh HD, but I'm not sure if that will relieve the problem.

I have Leopard installed on my main drive (MacPro). I was wondering if I could install Leopard again, but on another one of my internal drives for experimental purposes? Would I be able to choose which install to boot from? To clarify, I don't want to create another user account, I want to dual boot the same OS.

I am a network adminstrator (for a windows network ) but personnally an Apple User. I am savy with linux and unix enough to get around etc, so my knowledge is broad and indepth.I have never had issues with my own Macs in the past 5 years, but my friends MacBook has an interesting issue.She told me that the computer was doing updates, and she didnt want to wait for it to finish and just shut it off in the middle of some OSX updates.

I'm just not having luck with my last 3 MacBook Pros. My new 2.8ghz 15" now takes over 7 minutes to boot to the login screen. Before this happened, I recently copied 139 GB in sound libraries to my system drive. Before I went to work, I quickly closed the laptop and put in my bag. When I took it out of my bag several hours later, the unit was off and battery practically at full charge. When I started it shortly afterwards, it took forever to boot. It would sit there at the grey screen with the spinning circle, then get to the blue background (just before you get to the login screen) and wait there for a while. Most of the time I think you can hear the hard drive churning.
Once you log on, everything seems to be normal. I'm curious if perhaps that 139GB copy did something to the OS to slow it down. FYI it has 274/ 500 GB of free space left. Perhaps the hard drive didn't have a chance to park when I quickly put the laptop in my bag and I damaged it? To complicate matters, I have the MCE optibay installed with a 320 GB hard drive loaded in it. The only thing I can think of is to back up, and reload the OS. This should tell me if it's software or hardware related.

I have a macbook here that is stuck in a restart loop. It boots until it gets to the blue screen and flickers and goes back to a post screen and keeps retrying. It also displays a message that a crash log was written to file xxxxxxx.I can boot into single user mode and found the folder containing the crash log, how do I view that file in single user mode? If I can't read it in single user mode how can I read it, transfer it onto usb and view on my imac?

grey Apple screen on my Mac Pro. If I unplug my external hard drive (MyBook 1TB, formatted HSF, USB) it takes 15 seconds. From the Apple logo it takes another 20-30 seconds to fully load OS X. I really don't want to unplug my external drive every time I restart.
