Unable to boot from Install DVD to repair disk

I am trying to fix the following error Disk Utility gave me when verifying the volume:
Volume Header needs minor repair
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
I tried to boot from the Install DVD that came with my MBP and it simply won't boot from it. It DOES boot from a TechTools Pro Disk but I don't think tools to fix the problem exist on that. The install DVD shows up fine when I'm in OS X. I can burn DVDs, etc and everything just fine. Any idea why I can't boot from my Install DVDs?

As the computer will boot from the TechTools disk and you can burn disks, this suggests that the optical drive is OK, so what about the disk itself?
(A) do you have the right one; or (B) is it damaged or dirty?
If it shows up when in OS X, have you tried changing the startup disk in System Preferences? Or even simply clicking on the Install icon (you do not have to install once the disk is running)?
I am not a user of Tech Tools, but from what I have read on the forums, I am surprised you think it does not have the utilities to make the repair you need (have you tried). My own preference would be for Disk Warrior which has always worked for me.

Unable to boot from install disc to repair volume

Hi
Recently ran Onyx which told me the volume needs to be repaired (my Macbook has otherwise pretty much been running fine, perhaps a little slow on startup but no major issues). Not very clued up on using Macs sadly so did a little googling about how to go about this.
Am I right in thinking that I definitely need to repair this even though things appear to be running alright? If so, do I do this by booting from the install disc?
I attempted to boot my Macbook from the install disc to run a repair but I just can't seem to get this working! I put the disc in, restart the machine and hold C, but the mac seems to just boot up as normal. Am I doing this incorrectly?
Any help is appreciated, like I say I'm pretty hopeless!

Perhaps. See #6 in [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html] (or use the link in *User Tips* at the top of the +Using Snow Leopard+ forum), especially the yellow box there.

Unable to boot from install disk for needed disk repair

Hi- I need to repair my disk, but haven't been able to boot from the DVD. When I've tried (several times), I get a black screen with a long error message, ending in something like "hanging here." Any advice?
Thanks,
Laura

That is a kernel panic. Kernel panics on startup from an installer disc mean one of two things usually: 1. You are using an installer disc with an OS version that is not able to boot the computer model you have. Usually the version is too early for the model; 2. There's a serious hardware problem such as a dead hard drive or motherboard problem.

Hi guys I'm really in need of some help. I have an IMac I3 for a while now I've been having a problem of my machine refusing it shut down , it goes to a blue screen with a spinning wheel but doesn't shut down. And now won't boot from install DvD

Please some one help me ...
A) my mac won't shut down with external HD connected (if it's been used)
B) there are disk permissions that can't be fixed SUID stuff ..
C) I have now verified the Mac HD and it tells me it's corrupt in bold red writing and to start up from install DVD
D) it won't boot from DVD so I cannot run the repair , initially the machine was spitting it out on start up , now it appears to be attempting to boot off DVD , well it sounds like it is .... BUT it's hanging with the Mac Logo and a wheel ... For um .... 30min now...
E) weirdly when OSX is booted off the hard drive , it won't recognise the Install DvD or the applications one... It just spits them out....
I had an old PPC 17" and it was a beaut .... Never had a single problem with it ...
I bought this one December 2010 and it's been nothing but issues for a computer in excess of £1000 I'm extremely disappointed ... And weirdly the shutting down issue started when it was a week out of warrantee ... I feel conned and am almost at the point of throwing it at a wall and buying a PC

Ok so I've done what you said and this is what it's come back ....
I don't know that these are the errors , but they're the things which don't look right ...
Throughout the shut down there is a recurring line ;
It says ;
Com.apple.launchd 1 0x100600e70.anonymous.unmount 301 PID still valid
Then there are 2 more which I think are related ;
Com.apple.securityd 29 PID job has I overstayed its welcome , forcing removal.
Then the same with fseventd 48 and diskarbitrationd 13
Oh and on Launchd1 : System : stray anonymous job at shut down : PID 301 PPID13 PGID 13 unmount...
Then the last process says "about to call: reboot (RB_AUTOBOOT).
Continuing...
And stops ...
Hope this means something to you ... Thanks again for your help so far :-)

Wiped macbook pro will not boot from install DVD

I recently purchased an older MacBook Pro that came with the OS system wiped but it did have the original Install DVDs. The computer will not boot from the DVD. I have booted holding down the C key and nothing happens. I have booted holding down the Option key and it shows the Install DVD and I select this and nothing happens.
How do I get it to open up the Utilities from the DVD to install the operating system?

It could be a problem with the optical drive, but also may be due to the DVD's being for a different model.
Exactly which MBP do you have, and what serial numbers are on the discs ?.

New hard drive. Will not boot from install dvd.

Earlier this week, I dropped my computer.
It was probably a 3 foot fall.
Computer froze, so I restarted and got the flashing folder with question mark.
Started in internet recovery, and disk utility confirmed that I had killed my hard drive.
Got a new hard drive and installed. Started in internet recovery, formatted hard drive. Disk utility says it's good to go.
Was given the option to install Mavericks, but keep getting an error message.
Attempted to restart from install dvd that came with the MBP. Tried every startup shortcut there is.
Optical drive recognizes the disk, but I always get stuck on the gray screen with the wheel.
Reset PRAM. Reset SMC. Same problems. I do not have access to another mac or a PC with admin rights.
I'd rather not brave the Apple Store this weekend in the snow in a town that never gets snow (people drive poorly on a good day!).
Any tips?
Got the MBP in 2010, new. Was running mountain lion when I dropped it.
Thanks!

Yiou can't use Internet recovery on a 2010 Mac notebook to install any version of OS X on it. That is why you are getting that error. You have to use the original System reinstall discs that came with it to install OS X on a new drive or use the OS X reinstall disk to restore from a time machine backup.
Since your system doesn't seem to want to completely boot from that disc you should try an external DVD drive that connects by USB port as the built in superdrives are known to fail or partially fail at any time. Don't buy an Apple external Superdrive as they only work on Mac computer that did not originally come with a built in DVD drive. Any Brand external DVD drive will work on your Mac except Apples own external DVD drive.

Cannot boot from install DVDs

Hello.
I have been trying to reinstall 10.4 on my powerbook g4 1.67 15" and I am finding that my laptop is having a hard time booting from a DVD. I have tried starting up the computer holding down Option as well as starting up holding down C. I have tried using the retail black Install disc for 10.4. I tried what I believe is the original gray install disc (Mac OS 10.2.7 / AHT v. 2.0.4 / DVD v. 1.1 / 691-4676-A). I also mounted a copy of the retail 10.4 on my external drive. All attempts to boot from the install disc are unsuccessful.
When booting from retail 10.4 disc, I encountered a screen at startup requesting I install batteries in my apple mouse (keep in mind this is powerbook with nothing plugged into usb nor firewire). Plugging in a mouse just got me to a blue screen.
When booting from the gray dvd that came with my computer I am getting what looks like kernel panics (a distorted fractal band across the gray apple screen) when starting up holding down c. When I start up holding down Option, and select Apple Hardware Test I get a folder with a ? and mac face. The disc runs then stops and runs and stops. I have let it run for about 10 minuets and nothing comes of it.
When booting from the external drive I would get the initial install screens, where you select language and then the process freezes - the mouse freezes and the computer does nothing.
I also just purchased a new/larger HD, installed it and gave that a try - same results.
My computer & DVD are running fine all this aside.
Has anyone encountered this. Any suggestions?
I plan to give an external DVD drive a try, once I can borrow one.
Thanks.

Hi, vcou. The gray OS X 10.2.7 installer disc did not come with your 1.67GHz Powerbook and is of no use at all with it. Put that disc aside; it was shipped with an earlier PB model. Your PB requires a minimum of OS X 10.3.7 or 10.4 to boot, depending on whether it was produced early in its production cycle or later in the run. If you can find the disc that was originally shipped with your Powerbook, try to start the machine with it and see what happens.
The black retail OS X 10.4 DVD should work, provided your PB's optical drive is functioning properly, the disc isn't dirty or damaged, and the build of 10.4 on the DVD is at least the same as the one your Powerbook was shipped with (Build 8A428). Have you started the PB using that DVD in the past? If so, then of course you know it should work. If not, then you don't know for certain that it should work.
The best case here is that your retail DVD has worked in the past, is not scratched, and just needs a good cleaning. Or the drive needs a cleaning (get a cleaning disc from a local computer store, Best Buy, Radio Shack or record/DVD store).

Won't boot from install DVDs

I have an iMac here that refuses to boot from the install DVDs, no matter what.
I tried booting using the alt key, the C key, using the DVD in the Finder and restarting and via the startup disk in the System prefs. I always get one of the two following results: - either the DVD seems to startup, but then puts itself into a loop where it doesn't get to the installer and restarts the computer, - or it simply bypasses the DVD altogether and boots from the the internal hard disk...
I tried using various (full and legit) OS10.5 installation DVDs with the same results as above...
I've performed these operations many times in the past without problem, and It's actually the first I see a Mac that refuses to boot from an install DVD...
I thought maybe if firmware password protection enabled somehow... Would that do that?

You need an installation DVD to turn firmware protection off, ironically.
I doubt it is the issue here, though. If it was enabled, it would show a grey lock when you try to hold down option while booting up.
Is the iMac you are trying to boot from the DVD Leopard compatible as far as processor and RAM? My brother's iMac w/ 256 MB RAM cannot boot Leopard at all.

Power mac g5 wont boot from install dvd

i have a g5 power mac i had to replace the hard drive when i try to boot from the disc it freezes on the gray screen with the apple im use the retail dvd for the ppc can anyone help

Hello! You may not be waiting long enough if there's been a new drive installed as the OS on the dvd will be looking at the new drive to see if it's been formatted. It may take 10-15 minutes or longer to fully boot from the install disc. Tom

G5 Black & white video when booted from install DVD

It has been years since I installed 10.5 on our G5 so I can not remember if this happened back then but think it did.
When I boot from an install DVD (both the original G5 DVD with Tiger and the MacOS Leopard DVD) the video output drops to 1-bit (dithered black & white) which makes it very hard to discern the text on the shaded buttons in the GUI. The video card is fine - when I hold down the Option key on boot to select the DVD the video is full-color, but as soon as it switches to running from the DVD the video becomes low-rez dithered b&w.
Anyone else see this issue and suggestions on resolving it? The display is a Dell 17" wide model. I don't have another display that is easily swappable to see if it's a problem with it or the Apple DVI-to-VGA adapter.
The G5 tower is a first-generation 2x2 (2CPUs, 2GHz) with 2 DVI ports on the video card (can't recall which card I ordered back then).

Great to hear, thanks for the report!
I suspect what happened, was that the Install also changed some PRAM or NVRAM setting, those are where number of colors are held.
Some earlier Macs store these settings in PRAM:
Status of AppleTalk
Serial Port Configuration and Port definition
Alarm clock setting
Application font
Serial printer location
Autokey rate
Autokey delay
Speaker volume
Attention (beep) sound
Double-click time
Caret blink time (insertion point rate)
Mouse scaling (mouse speed)
Startup disk
Menu blink count
Monitor depth
32-bit addressing
Virtual memory
RAM disk
Disk cache

Powermac G5 won't boot from install dvd.

The hard drive in my Powermac G5 quit, so I put in a new one that was formatted. I put the install DVD (OSX Server 10.4) in and booted. Every time I try I get a kernel panic. Everything else in the computer works. I have tried putting it into target disk mode and installing the OS using another computer, but it won't let me because the computer doesn't run tiger. I have also tried putting the functioning Mac into TDM with the install disk in it, then booting it from that but I still get a kernel panic. The computer was functioning normally before the hard drive crashed.

OK, that's a Late 2005 G5...
http://www.everymac.com/systems/apple/powermac_g5/specs/powermac_g5_dual_2.3.htm l
Pre-Installed MacOS:
X 10.4.2 (8E90)
Maximum MacOS:
X 10.5.8
So, If that Install Disc is in fact 10.4.0 as I suspect, then it won't work for your G5... no drivers.
I can only see a couple of options at this point...
1. A newer Install Disc.
2. An older Mac & a Firewire drive to install it to, update to 10.4.11, move FW drive to G5.

G4 AGP, problems with Graphic Cards and booting from Install DVD

I bought a G4 AGP (with DVD) on Ebay. It has Mac OS9.2 installed and its working correctly so far. It has an additional GraphicsCard in a PCI Slot, on which the Monitor is connected.
1. The AGP Card doesn't give any output signal... I wondered if this would be the reason that somebody installed the additional Card...
2. The AGP Card doens't show up in the Profiler... is this normal? According to other users this seems to be a common issue...
3. I would like to install X 10.4, but when booting from CD, the process stops after a few seconds... and there is no signal on none of the video cards. I tried to remove one or the other card but no luck...
the firmware is uptodate and the Install DVD is correct aswell, I just bought it from AppleStore...
I don't have any original CDs available, so I cant run a hardware test.
Anybody?
G4 AGP Mac OS 9.2.x

The AGP Card doesn't give any output signal... I wondered if this would be the reason that somebody installed the additional Card...
Probably. I'd take out the bad original card and replace it with the additional card. Then, check and see if that's what caused the problem. Then only other choice is to take it to the Apple store and have them check it out.
I don't have any original CDs available, so I cant run a hardware test.
You can either contact the seller and complain about the missing disks or buy replacement disks for your machine. Give 1-800-MY-APPLE a call. The AHT disk should cost about $20. I don't know what the others would run.

Wont Boot From Install DVD

I need some help - I just brought home a brand new 27" iMac. It boots just fine from the internal HD. I need to do a complete Time Machine restore, as this iMac is a replacement for one that they can't seem to fix. Anyway, I load the Snow Leopard DVD, it pops up the OS X FInder icon, I tell it to go to utilities, and that I want to restore the entire hard drive. It then reboots - sort of. The DVD does some stuff, then the machine sits there with the gray apple logo on it. Been there now for 15 minutes with nothing happening. Any help would be greatly appreciated....
Jim

The first thing I would suggest:
- Shut down the iMac with the disc still in the drive
- Once it is shut down, Press the power button and hold down the C key on the keyboard in order to boot from the optical drive. (Hold until Apple Logo appears)
- Once disc loads, select a language and click the arrow
- The installer will prepare
- Up on the menu bar, click Utilities, then Restore from Backup
- Follow on-screen instructions
After that you should be good to go! Hope everything works out.

2008 MacBook Pro won't boot from Leopard DVD or Target Disk

Yesterday I was working on my MacBook Pro. I use FontExplorer to manage fonts. I ran the conflicts diagnostic looking for missing font files, which returned about 200 results (I was expecting this). I've moved the fonts installed by Adobe/Microsoft out of my fonts folder in my user library (user library, not system). For some reason the computer started to become very slow, to the point of beachballing. The freezing seemed to start and stop. I was able to close FontExplorer and Illustrator without force-quitting. I tried to shut it down gracefully at that point but it froze up again, so I hit the power button to force a restart. It started up but now it hangs on the gray screen right before the Apple logo. The logo doesn't come up, I can hear the drive spinning as normal but it doesn't do anything.
I've tried booting from a retail copy of the Snow Leopard, but it doesn't work. I can hear the disc spin up in the DVD drive as though the computer is about to read it, but nothing happens. It just stays on that same blue screen. I've tried booting my MBP in Target Disk mode from my iMac. The target disk icon appears, however it just sits in the middle of the screen and my drive doesn't mount on the iMac. I've noticed now that the white status light on the front of the MBP (on the latch) doesn't come on, and if I cover the speakers the backlight doesn't turn off.
What do I do now? I have an enclosure I could use to try and boot the MBP's drive from, but I'm running out of options. I'm really starting to worry about my data. I have a major school project that's already late which is on there, and I don't have a recent backup. If I don't hand it in... let's not go there. I don't understand how this could happen; I take very good care of my computer, I turn it off when it's not in use, and I run Cocktail on it once a day which does a SMART status check.
Help?

sig,
The first thing I tried was booting from the install disk. The 2008/2009 MBP's aren't able to boot from a retail DVD of Snow Leopard, which is why I ended up using the original hardware-specific install disk that shipped with my computer. That didn't boot either. I was able to view the drive in Disk Utility when it was in the enclosure, but the partition with my data on it would not mount. I attempted a repair disk on the drive but that failed. It wouldn't mount in Terminal either. I considered trying to rebuild the volume catalog using TechTool Pro but there's the possibility that could actually make things worse. So I've taken it to the repair shop. They're running it through DiskWarrior overnight, last I heard there were 60-something thread errors. Yesterday my SMART status was fine, today my drive is dead. What happened? Hoping for the best (but expecting the worst).

Lost Admin Rights - Can't Boot from Install DVD

On the first day I clean installed Leopard. Apart from one or two minor issues (since resolved with help from you guys) everything was working fine -- until now?.
Today, I tried to update NeoOffice as I've already done twice since installing Leopard, but can't get beyond Administrator Name/Password. I only have my account on the machine, so popped into system preferences to see what's going on:
My account is now "Standard" not "Administrator"? Other posts suggest Reboot from DVD/ Utilities/Change Password etc.
2. But I can't change any settings like "Start-up Disk" or "Account Privileges" in System preferences without Administrator Name/Password.
3. Can't find a way to reboot from DVD (Have tried "C", "Option"). Just keeps coming back to Login Screen.
Help!!!!!!!!!!!

I have the same problem. After installing Leopard all my accounts were changed to "Standard". So I try to boot to the CD and hold down any boot commands (c or command-s or option) and none of these work. Talked to Apple for an hour on the and they want me to take it to an Apple because there is firmware that locked.
