Boot from Disk warrior disc?

I was able to boot from the diskwarrior disc on my 2008 Macpro.
I can not on my new 2010 Macpro. All I get is the white apple screen.
why not?
The system drive graph is a mess and I need to rebuild it- suggestions?

I didn't think anyone used the CD.
Install OS X to a small 30GB volume. Use that and keep it only for maintenance and repairs. Running OS X in any fashion is better and easier to rebuild the directory - OS X does not like total lack of a VM. Plus you can run multiple programs, boot faster, and you are using the latest OS X and Disk Utility and not locked into a fixed version. Same holds true for using Disk Utility, only use the DVD when there is no other means.
And with small affordable drives, or even SDHC Flash Memory card you can boot and run OS X off small 8GB (some have trimmed it to fit on 4GB but have to do that first on a hard drive).
I would clone the system (SD or CCC) and run DW against the (updated) backup image regularly. Then switch over and boot from clone (insure it works) and then repair the main system (and other drives).
With 4-5 internal drives, Firewire, and USB, lots of options for alternate boot volumes, and you can take a 1 or 2TB drive and just shrink and create a small volume on the end for such purposes.
So no need to rely on booting from CD or DVD, ever.

Boot from Disk Warrior?

I tried to boot from DW CD and all I get is a grey apple screen.
I dragged DW image to an external drive and it will not launch.
A warning tells me to uncheck ignore owership in the info - but there is no such option.
Anyone able to run DW on the system of a 2010 Macpro?

Disk Warrior doesn't yet support the latest Mac Pros: http://www.alsoft.com/diskwarrior/support.html. You'll need to get a second bootable hard drive/partition and install it on that to repair your normal hard drive/partition.

Cannot boot from Disk Warrior 4.0

Is any one having this problem ? When I try to boot from the Disk Warrior disk it just goes to the apple icon then restarts. I must have tries for 20 min holding the "c" key watching my system restart over and over again never mounting the disk. It has been totally unsuccessful using DW 4.0. Its a bummer because I am a fan of this product.

DW dose not boot with the new intel macs!
As you noted you cannot boot an intel Mac from DW 4. Disk Warrior 4.1.1 is the intel version and now boots a version of Leopard from the DVD (the previous version booted into Tiger). If you can't get it to boot using the keyboard at startup try going to System Preferences - Startup Disk and setting to boot from the DVD and restart. If your Mac still refuses to boot from the DVD then as others have already indicated you may have a hardware problem.
Have a look at the Disk Warrior Support Page to get the free update to 4.1.1

Can no longer boot from ANY OS disc on MBP

I recently purchased a 15" 2.16ghz Core Duo Macbook Pro. It came with the original 10.4.5 discs. The previous owner installed 10.6 on it using a retail disc, then upgraded to 10.6.6. I had planned on upgrading the original hard drive. However, I cannot get the laptop to boot from the original discs or my own retail 10.6 disc. I've tried a number of different approaches (booting from an external DVD, holding down "C", holding down "option", attempting to mount in on the desktop first, etc.). Either the machine hangs or it ejects the disc (when using the internal drive). Nothing seems to work. Both the internal drive and external drive have been tested and work fine. Is it possible that when upgrading to 10.6.6 a firmware upgrade was done that won't allow the machine to boot from a disc containing an earlier version? I don't know what else could be causing the issue. The laptop has not displayed any other issues. Thanks for any suggestions or explanations.

I don't know how much help I'll be to you. Seems to have a lot of posts lately about not being able to start up from the install disks.
I assume you can still boot up from the internal drive.
When you hold the option key to start, does the screen come up with the option to choose a startup disk and is your Install Disk in when you attempt this?
While booted up normally, does the Install Disk open up with the install OSX menu? If so, does going through the install menu reboot the computer from the CD automatically?
Even if there were a firmware upgrade, seems like you would be able to use the 10.6 Install Disk to boot from.

G4 won't boot from any Linux disc I put in it and c key no longer boots cd

I have a G4 Powermac (sawtooth, DVD drive, 512 MB RAM, 30 GB HDD) which has started refusing to boot from any Ububtu discs I have all of a sudden.
I'll be more specific. I've previously been able to boot from Ubuntu 6 cds (originals from shipit, not burnt) as well as Ubuntu 7 (burnt disc). I haven't made any changes to the system that should stop it booting from them. Currently installed on the hard disc is System 9 and Puma. It is still booting ok from my System 9, Puma, Panther and Tiger discs; but when trying to boot from my ubuntu discs (I've tried all of them to eliminate the possibility of a stuffed disc) the screen goes black for a second as if it is starting to boot, but then it kicks me to the flashing folder screen you get when it can't find a startup disc. Oddly enough the background colour of this screen isn't grey like usual. It's orange. I've never seen that before. If I leave it sitting at this screen after about 30 seconds or so it starts up from the hard disc on its own.
Another odd thing: the c key no longer forces the machine to boot from the cd when held on power up. This is extremely odd, as holding down option brings up the startup disc selector, and cmdopt+shiftdel also works. I've tried everything I can think of. Used a different keyboard, reset the NVRAM (by cmdopt+pr and my manually going into open firmware and doing a "reset-nvram" and "reset-all"). I've tried the PMU reset switch on the logic board. I've tried using different drives. In all cases it still refuses to boot from cd when holding c.
I don't think that the mac refusing to boot while holding the c key is coincidental. I believe that whatever the issue is that's causing this issue is what is also causing the mac from not booting any Ubuntu discs. It's a very strange problem and upon searching around, it seems this doesn't seem to have happened to anyone else before. Any advice will be greatly appreciated. Thanks.

Hi, yoshi -
I just have to be rush to get the cd in the drive and then to hit cmdshift+optdelete before it's too late...
You should also be able to use Startup Manager to choose the CD as the boot volume -
Article #HT1310 - Startup Manager: How to Select a Startup Volume
A feature not discussed in that article -
Once Startup Manager has loaded, if the CD is not in the drive you can press Command-. (Command-periodkey) to open the drive - this should work even if another disk is already in the drive. Insert the disk you want to use, close the tray, wait a few seconds for the disk to spin up and get recognized, then click the circular arrow icon on the left - this forces a rescan of the available drives, which should result in an icon of the new disk appearing in the array. Click it to select it and then click the straight arrow icon on the right (or press Return).

Folder with question mark + wont boot from disk

Hi
I am trying to reinstall a powermac g5 from the disk, using a old hard drive that works.. (formatted in NTFS) (hoping that when selected to boot from disk, mac will then erase and reformat it)this image is presented when i hold down the option key and the disk ejects this other image is presented when i hold down C (folder with question mark blinking) and the disk ejects... also presented if i boot normally.... Could some help be offered please??????
Powermac G5
Thank you in advance

Yes, you must Format it HFS+ first...
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

Problem with kernel panic message - Cannot boot from disk or usb

Hi Everyone,
I was wondering if someone could help me with a problem I've been trying to tackle for the last few days. I have a 24" iMac 2.33 Ghz Dual Core, with 2 gigs of RAM. A couple of days ago my computer crashed, and when I tried to boot up again I got the infamous grey screen kernel panic message ("You need to restart your computer..."). What's worse is that I get the same message when I try booting from my external drive and the installation disk itself.
I've basically planned on formatting since it's been a while anyway, but since I can't boot from my external drive or the installation disk that came with my computer these are not options at the moment. I can only get into the computer via safe mode. I've used disk utility to verify the disk, and it comes up with no errors. Anyways, I'd really appreciate if anyone had any advice on this. I've scoured the internet for advice about kernel panic messages, and they all suggest booting from disk or external drive etc., which is not a possibility for me right now.
Thanks

If you get a panic when trying to boot from the installation disc, and the disc is not scratched or dirty, then you have a hardware fault.
Make a "Genius" appointment at an Apple Store to have the machine tested.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

My mac mini wont boot from disk

Boot Issue BIOS won't boot from Disk

Ok, heres my issue. First I was having issue installing Win2k and found I had to disconnect my USB ZIP drive to boot (BIOS Option was disabled)(This is just a note). After installing WIN2k on a WD300BB I was having no issues until I removed my Win2k CDROM disk. At that point the bois (seeing the drive) would not boot (Insert a bootable disk error). To get around this issue I created a bootable nt floppy disk to boot the hard drive.
I also attempted to do a fdisk /mbr with no help. If i put the win2k cdrom into the cdrom drive and have one option to boot from CDROM it will boot from disk. I do NOT hit a key to boot from cdrom. I also cut wire 1 & 2 from IDE cable.
Any other ideas?
Thanks

Thanks for the reply, the IDE cable is cut and there are no jumpers on the drive. This is a bios issue. If I boot from floppy to Win2k, this system works greate. But it will not boot off the hard drive with out assistance.

Blinking folder with ? --- unable to boot from disk, have data on hard

drive that isn't backed up
I am fairly new to the MAC Os and have gotten this error twice now. Yesterday it was resolved by resetting PRAM - today not so much.
I am not sure how to proceed - I have not done a most recent backup and was working on new files on my hard drive.
Any advice?
I am utilizing an external hard drive for space, so the OS is fairly "empty"
Hope someone can help!

here is where I am at -- I didn't think I'd need to say that I've done the first steps, but regardless I have booted from the install disc, reset the PRAM and now I am at a dead end. If I choose continue on the first screen after it boots from the CD, agree to the terms -- I'm assuming there should be an option to select --
On the screen that is "Select Destination; where do you want to install Mac OS X?" it is blank, the options and continue buttons are greyed out, the only option is to go back --
am I at a dead end?
hypothetically speaking, if the system is in need of repair, is there a way that I can have the service techs retrieve the mail / cal / etc data that was not included with my last backup?
thanks again --

HP 3500 MicroTower doesn't boot from disk!

We are facing a very strange issue with HP 3500 , the machine can't boot from disk ! only way to get it to boot is to pxe boot it.
Whenever it can't find a Pxe server to boot from it failed to boot from disk with an error that "No boot disk detected ... "
Disks are detected correctly in the setup/bios and quick smart check tests are passing successfully.
I have tried to disable the network boot but this didn't help as well, it indeed skipped the Pxe boot step but it still fails to boot from disk with the same error.
The OS installed on the machine is Ubunutu 12.04
Note:
We installed extra 2 disks to this machine and 2 extra network cards as well , not sure if this is related but I thought it worth mentioning it.

Losing User Accounts on many machines. Cannot boot from Disk. Help!

As many of you know there is a bug going around where the OS “forgets” what user accounts are on the machine. The only user at login is “Other”. This has happened on 10.6.5 and 10.6.6. In the past I have been able to fix this issue by booting from the Snow Leopard disk, change the root password, login using root and re-add the user accounts back under system pref’s. The issue I’m currently having is that two Mac Pros will not boot from disk, external HD, or into single user mode. None of the key commands work at boot up.
The computers do not chime at boot and the apple logo shows up very quickly. I’ve tried resetting PRAM and the logic board. I now have two BRICKED machines and cannot afford to have any more go down.
Any help on this issue would be greatly appreciated!
Thanks

I just had a very similar problem this morning on my iMac. Plain white screen on boot-up. No Apple logo. No booting from my SuperDuper clone, no booting from the DVD, no booting into Startup Manager by holding down the option key, no booting even into Apple Hardware Test. I was getting ready to take it in for service.
What finally fixed it was resetting PRAM three times. Hold down command, option, P, and R, and keep them down until you hear the third startup chime. That's what finally breathed life back into my iMac.

Can't boot 10.5.8 MacBook Pro from Disk Warrior while restarting using "c"

Hello,
I am helping a friend maintain her 2008 MacBook Pro (10.5.8). Have safe-booted several times, and repaired permissions.
Since she is having minor issues, I brought over my Disk Warrior v. 4.1 (CD rev. 42) which has done wonders for other Leopard Macs.
Her MacBook Pro just refuses to boot from the Disk Warrior CD when I hold down the "c" key while re-starting. It starts as usual from its OS. This has never happened to me before. So I cannot use Disk Warrior on her comp, as far as I know.
Whenever I have used this Disk Warrior CD on mine and other 10.5.8 computers, and booted holding down "c" key, everything goes swimmingly.
Grateful if anyone can anyone offer a suggestion...
Could it be her drive, her logic board, my not re-setting PRAM on her computer? Or a total mystery?
Many thanks,
Neil

Most likely because you have a version of DW that cannot boot that model. The current version of DW is 4.2. You can download DW 4.2 and create a new CD but that requires burning a new CD as part of the updating process.
Is there any particular reason why you cannot repair the disk using Disk Utility? Just boot from the Leopard installer DVD or the original installer DVD that came with the computer, then use DU from within the installer (Utilities menu) to repair the hard drive (repair, don't verify.)
