Wont boot on 10.6.3 disc

I need to reinstall my OS.
I cant boot of the 10.6.3 disc the computer just sits there with a mac symbol and never boots off of the CD. I tried imaging the disc to a thumb drive but that doesnt work either. Im baffled.
Does anyone know how to fix this? I can restore if I can just install the OS.

Every i5 MBP has been shipped with a model-specific build of 10.6.3 or later preinstalled, and requires at least that version and build to start up. Your retail disc probably contains an earlier build of 10.6.3 than the one that came preinstalled on your machine, and that's why you can't boot from it.

Ibook G4 OS 10.4.11 wont boot up.

I was deleting a second user account and whilst it was copying that user's files before deleting the power was switched off. Starting now gives the flashing question mark icon after the start up chime. It wont boot up from the instal disc either (holding c while powering up). I also tried command-option-p-r at power up with no effect, and option key with the install disc to use the hardware test. This last gave me an arrow cursor but nothing else. The user guide suggests that the only option is to reinstall the operating system but to do this it needs to read the install disc which it can't. Help.

The new disc finally arrived from Apple - labeled "Mac OS Tiger DVD 2Z691-5599A".
- Inserted disc and start up holding C key ... sounds of disc being active followed eventually by flashing question mark. If "disc eject" button is pressed the question mark stops flashing. The only available action is to switch off with power button.
- restart holding down option key (to try hardware test) ... again sounds of active disc, this time followed by blank screen with movable arrow cursor. This time apple-control-power was effective - not to restart but to shut down.
- ejecting disc by starting whilst pressing mouse pad works.
- shutting down seems to vary .. sometimes just a quick press of power button, sometimes has to be held for a few seconds before shutting down.
Maybe Apple have sent the wrong disc?
There is a repeated quiet clicking throughout which I interpret as the hard disc trying to run. It seems like the hard disc needs a little nudge like the needle in a scratch on a vinyl LP!
Reading more from http://support.apple.com suggested a few things to try:
- start up in single user mode (holding Command-S) : failed
- start up in safe mode (holding shift key) : failed
Back to the OSX 10.5.6 install DVD I tried previously: this seems to work and gave a utilities menu:
- "System profiler" found the hard disc under serial ATA - Intel ICH7-M AHCI
- "Disc utility" failed to find it.
- "Terminal" loaded but when I tried to enter sudo nvram boot-args="-x" as suggested to start in safe mode it returned "command not found" so that got nowhere.
- "Restore system from backup" utility isn't active, presumably because it doesn't recognize a hard drive to restore it to?
I have an external hard disc used for some back up. When I connected it to the USB port both system profiler and disc utility found it ok but "start up disc" utility didn't. Unfortunately it doesn't have a system on it. If it did could I start up from it and would that help? How would I install a system onto it? (I'm typing this on an oldish Powermac G4 desktop running OSX 10.4.11)
I will phone Apple first opportunity to check the correctness of the disc. However I do wonder if it can be any better than the 10.5.6 disc anyway.
It seems that what I need is some way of getting access to the hard disc.
Sorry for the length of this - but any more suggestions would be much appreciated.

24" iMac - Wont boot from HD or disc... Help!

Hi guys,
Just been working on iMac, forget the exact spec but it's a 24" Intel 2.something Core 2 Duo or whatever it is, 4gb DDR2 RAM, gotta be about 2 years old to the day and after my last 2 Macs have lasted forever, never developing a fault, I didn't take out Applecare... Perhaps I had a bit too much faith...
As I say, just working away and all of a sudden, upon putting a video in Quicktime to full screen, the whole image has kinda of condensed itself into the top 20% of the screen and started slightly flickering the image. I've tried quitting some of the programmes, but neither the mouse nor leyboard have been responding so I've just had to turn the computer off.
I've gone to turn it back on, and after about 30 seconds, it's got as far as the grey screen but then the little spinning progress indicator pauses and it does nothing else.
I've reset the PRAM and that made it take longer before it froze but ultimately did nothing.
I've now tried getting it to boot from the Snow Leopard disc but this does the something, until after about 3 - 5 minutes, the screen goes all pshychedlic, like looking at an old school TV really close...
So looking for any suggestions on other things to try before I have to take to my local store... Any hazard a guess at what may be up with it?
I've got a back up the whole computer but I don't think this is a software problem, I'm assuming it's going to be a hardware one?
Any help at all would be much appreciated!

Ok, tried Safe Mode and that wont boot either. Saw a little progress bar on the grey screen though which made a change, but ultimately, it crashed once that had disappeared.
I've just noticed that at the point when the progress wheel stops spinning, a pattern of dead pixels appears across the screen that aren't there when the progress wheel is spinning.
The more I talk to people about this, the more graphics card seems to come back as the likely culprit, based on the fact that:
- it started by me putting a video to full screen
- the fact the display went weird when it first happened and also it plays up after it crashes with the psychedelic colours
- it wont boot from HD, disc or now in safe mode either, however it does run AHT fine.
- I've hoovered out the vents on the iMac and somehow it seems slower than it was before (bit odd)
- the dead pixel thing mentioned above
So now thinking it may be time to get a new graphics card?
Reckon this is likely, even though the AHT hasn't picked up any problems? As mentioned earlier, I'm not too concerned about it would seem it doesn't particularly test the graphics card too much, so all just seems to point towards it.
Anything else that I could do to single this out as the likely culprit?
Guess this is a chance to upgrade!

G5 Wont boot.

I've searched and i've searched, and i can't really find a similar problem to this. It would seem most G5 boot issues are ram related..
Anyway. It's a G5 1.8 SP, launch model. Yep, about 7 years old now.
Running 10.5.8
The boot HD is a 500GB and only has 1.8GB free. Also have a 160GB for files which has about 50 meg free.
3.5GB ram (6x 512's, 2x 256's).
Graphics card is a radeon 9800 pro, with a noisy broken fan.
So. This computer has had a hard life. Seen lots of lan parties, and used to play allot of games back in the day. Up untill recently (say, the last year) it was working flawlessly. Then one day after going to a lan, it wouldn't boot. I reseated the graphics card, and it worked fine. Moved it again a few months later, and same deal. It's now got to the point where i'm affraid to move it, incase it stops working.
Well, last night i hopped under my desk to boot up the file G3 (which boots up flawlessly every time). I sat back down in front of the G5 again, and it had frozen while i was under the desk (i didn't even touch it!). The mouse was working, although it was extremely erratic, it would zig zag accross the screen while moving it. Everything else had frozen dead though.
So i rebooted it, and black screen. **** it. I reseated the graphics card, and it seemed to work. It got to the grey screen fine, with working pinwheel. Then went to the aqua blue back ground and stopped there, The screen would 'refresh' i guess you could say ever 20 seconds or so (go blank, flash, and come back as aqua blue). The mouse worked fine also.
I tried reseating the card again. Booted holding CMDSHIFT+PR, that rebooted successfully, but now it won't go past the grey screen. It just pinwheels for eternity. I got out the leopard disc and tried booting off that, but the disc drive appeared to be having troubles (the DVD drive has always had issues - it's a sony)
So i tried something else, and got the old Nvidia FX5200 that came with the computer, and tried booting of the disc again, and it worked! The boot disc works fine. There's no graphical glitches, no problems at all. I ran the disc utility, it reported no problems. But there were quite a few permissions broken, that it could NOT fix. A few front row (as in the program) permissions, a 'backrow' frameworks, and a few other frameworks that error'd.
Ran the profiler, and all the ram shows up, and says OK. It's also reading and using the nvidia just fine, despite it being unused for some 5-6 years.
TL;DNR
G5 launch model has had some issues with the graphics card in the last year.
Last night it died again, reseated card and now OSX only boots to the grey screen, with a working pinwheel.
Installed the old FX5200 graphics card
It succesfully boots of the leopard disc, ram appears to be all in order, Disc utility came up with some bad permissions, but reported no problems with 'repair disc'
The computer still wont boot past the grey screen, even with the different graphics card.
It doesn't boot in safe mode either. Infact, that only makes things worse, the fans do the spool up thing that happens when you get a kernal panic.
Any ideas?

Well i managed to clear 20 gigs off, this is the most space the computers had in probably a year, i know it can (normally) boot with that much space as it has done so with less for a long time now.
It's gone back to the blue screen. It will get the grey spash, with pin wheel. moments later it flashes to aqua blue as it normally would when loading OSX, but it stops there. And will flash every 20 seconds or so and try again, for infinity.
I re-installed the 9800, and same deal.
I'm also running it with the boot disc at the moment, and it's all running fine, so i thing the 9800 is ok.
I'm going to try and repair the disc and permissions again, and see if it has some more success now it's got a bit of room to play with.

Dm4 wont boot- hard disk error but passes hard disk test

My dm4 laptop froze yesterday and I was forced to restart it- it is 3 years old but I have had no issues with it. When trying to reboot it will not start and if I run windows repair it comes up with the failed 2 hdd error. I thought it was a hard drive failure as I originally got a 305 error code when running the hard drive test. Upon opening system diagnostics I ran the hard disk test and it passed no problem. However if I run any of the other tests- start up, run in, or system tune up, I get the error Hard Disk 1. I tried the hard disk test again and it passes. Ive run Avg virus scan and found no threats. I have no idea what is going on- I did a BIOS rollback and the computer still wont boot up. What is happening and can I recover my data?

With the intermittent errors,it sounds like the hard drive is failing and will need to be replaced. A retail laptop SATA hard drive can be used. Just be sure to get one of at least equal capacity as the original in order to use Recovery Discs. It can be larger, but not smaller capacity.For instance if you have a 500GB hdd you could use a 750GB hdd but not a 320GB hdd.
As for whether it is possible to recover your files it depends on how much life is left in the hard drive.Many times you can remove it, attach it to a USB Adapter or install in a USB Enclosure to plug into working machine via usb port and copy files over to the hard drive of host machine.
If you need more help selecting/replacing the hdd post back with full Model & Product Number as listed on the Service Tag attached to bottom of laptop.
How Do I Find My Model Number or Product Number

My early 2008 3.1, 2.8 Ghz wont boot up.

     My early 2008 Mac Pro, 3.1, 2.8 Ghz will not boot up. I get the chime then the gray screen, then it continues to boot for approx. 15 seconds after which the gray screen freezes up. Previous to this condition I started getting a half orange frozen screen that would jump up and down while I was using the computer. Also, there were times during normal use where the screen would freeze with lots of lines all over that were small dashes. And now the computer wont boot past the gray apple screen. I have tried "C" boot from the install disc, "Shift" boot, "Option Boot", "Command-Control", "Command-Control-P-R", and multiple normal reboots and nothing past the gray screen. The only "glimmer of hope" is that when I do a boot from the Install CD, "C" or "Shift" I get a box which says I have to restart my computer using the "reset button" ? or pressing the power button for 2 seconds which led me back to having to restart and the gray screen situation all over. Thanks, I have a feeling I know what you are going to say. God Bless.

Dear Grant,
     Thank You for your quick reply; I believe your right, Sounds like this is just the normal response for problems like mine. I am hearing more and more about the video cards that were implanted into these Mac's. One guy said "don't even bother, get a new computer and save yourself the expense of future cards."
     And when you think about the behavior of my computer it makes so much sense. The computer starts up just fine, you get the chime, it loads to the next correct screen, and continues to boot up until its time for the video card to start spitting out video, then it freezes up.
     Excellent, I hope all is well.
Thank You very much,
God Bless All,
Bob F.

Wont boot from cd???

I have a slot-loading iMac that wont boot from a CD.
Does anyone know why? I have tried holding C and choosing the CD as a start-up disk but it doesnt work. The CD i am trying to start-up on is the Mac OS 9 CD.
Can anyone help??
Thanks Daniel.

Did you have any luck on this?
I am having the same quandry. I have a slot-loading 450MHZ imac which I purchased used with 10.2 installled on it. When I tried to upgrade to 10.3 using my black retail CD I own I was told I needed to upgrade the firmware. Then I discovered that Classic had been deleted from this computer, so had no way to boot in 9.2.2 to install the Firmware update....so I figured I would have to start from scratch from my white 9.0 retail CD and do the upgrades to 9.2.2, but it wouldn't boot from the white CD.
Then I followed instructions I found here and used my 10.3 disc to access Disk Utility and reformatted the HD with the OS 9 Drivers (losing the 10.2 install it had in the process), and reset the PRAM twice.
So now I just get a gray screen with the flashing Question Mark in a folder. I have tried an external CD drive to confirm it's not a problem with the optical drive and have booted from the OS 9 CD on another slot-loading imac to confirm it's not a problem with the Disk. I have a 9.0 CD and a 10.3 CD but nothing in between.
Still no luck...

Imac wont boot, stuck loading, all i see is apple logo and spinning cycle

Power down (assume you have already tried the SMC reset) and insert the Applications DVD that came with your new iMac. Boot up while holding the "D" key down (may be best with a wired keyboard) to run the Apple Hardware Test according to these instructions:

IMac wont boot from CD

I am selling my iMac so want to reformat the HD and do a fresh install of Leopard.
When I try to boot from the system CD I get the grey screen, I hear the CD Drive reading the disk, then the computer reboots. The same thing happens every time no matter how I try to boot from the CD. When I eject the CD, or boot from HDD, it loads the OS fine. It just wont boot from the CD.
I have tried:
Booting from CD by holding the C key during startup
Booting from CD using Startup Disk in System Preferences
Installing OS from the 'Install Mac OS X' application on the disc
Holding the option key during startup and selecting the CD drive
Resetting the NVRAM
Verifying the HD in disk utility
Verifying the CD in disk utility
Verifying and repairing HD disk permissions in disk utility
Running the install on my MacBook to check the CD (booted to the CD and started install process fine)
I have searched for previous discussions that reference this issue but could find none with this specific problem. The CD drive reads other media fine so I don't think it's a hardware issue.
Any help would be much appreciated.

Clean the disk?
Dirty lense?
The bottom of the disk must be free of scratches and especially human fingerprints which the oils can trasfer insdie the machine.
Use a bit of rubbing alcohol on a very soft clean cloth and polish ot a shine before using the optical drive.
Order a replacement disk from Apple, buy jewel cases that suspend your disk, the plasic/paper sleeves Apple provides aren't good.

Intel mac mini wont boot after system restore

Hi,
I ran the system restore on my intel mac mini using the genuine leopard cd that came with it.
Now it wont boot. When you press power the light comes on but it does not chime and there is not video output to any monitor.
Anyone know what could be wrong?

Welcome to Apple Discussions!
You picked 10.4.1 in your profile.
Intel Mac Minis at minimum came with 10.4.4.
If it came with a 10.5 genuine DVD, it most certainly was not running 10.4.1 or 10.4.4. Perhaps you mistook one Mac Mini install DVD for another? Does your Mac Mini have 4 USB ports on back? What does the 10.5 installer disc you used look like?

IMac Wont Boot Question.I cant find an answer.

Ok Heres the story.
I have an iMac 20" display Intel Core Duo.
I came home yesterday and it was locked up.. I had to turn it off manually.
When it rebooted it started up but was stuck with a folder with a "?" on it.
I know it has to be the HDD.
I booted it from the snow leopard DVD and went into disk utlilty and repaired and verified the disk. The HDD shoes up in disk utility with the Macintosh Partition.After I repaired it it still does not appear as an option to st it as a start up disc.. I dont think the HDD is bad.. But I am not an expert
To be honest I dont care about the iMac I just want the data. I back up but I did not do one in a month or so and there are some things I want. If I removed the HDD and plugged into another mac would I be able to get the data off? I have one of those sata to USB adapters..
Any help would be appreciated let me know if you have any ideas

Do you know why it shows up in Disk Utilty but it wont boot from it?
Because the computer can't find a bootable OS on it. This is much more complicated than just seeing the drive.

Disconnect all peripherals from your computer.
Press the Power Button and immediately press and hold down the Command and the S keys as the machine starts up. This boots you into Single-user mode and you should see white text appear on the screen.
When you see the # Command prompt, type /sbin/fsck-fy and hit the Return.
Now sit back & let your computer do its thing. This should take approximately 15 minutes or so. Depending on how messed up your computer is. Just be patient.
If and when you see the message File System was modified repeat the steps above again & again until you hopefully see the message "no problems were found." When that happens type reboot and hit Return again.
If these steps do not work then boot from your install disc to repair disk. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.

IMac G5 froze and now it wont boot? Help!

I have iMac G5, its 3 years old. I was playing a game and all of sudden it froze.
-First tried to resarted the computer, it wont boot up and there was no sound.
-Secondly, I manage to reboot, but it gave me the gray with Apple Logo and did not reach to the login screen.
-Thirdly, it booted up, though it was very sluggish and slow.
I manage to use Disk Utility, it seem to be fine. I shut down the computer it just froze.
I restarted the machine nothing, just a black screen. Only once I turn on with sound, still black screen and the FAN started to rev-up. I took out Ram from the machine and to see if I can restart it. I get power, No sound, and no gray screen. I have no clue what happen and how to fix it.
Any tips will be appreciated.

Thanks

Well, you could try booting from your install disc, and either running Apple Hardware Test, or using Disk Utility to try and repair the drive, but I still think it's the logic board:
1. Insert the Mac OS X Install disc that came with your computer, 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. (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.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then if possible, reboot and run Permissions Repair from your hard drive.
Let me know if you manage to revive it.

Power Mac G5 wont boot past the Apple Logo

Mac: Power Mac G5 2.7Ghz DP w/ 4gb RAM (2x1gb, 4x512mb), Leopard
Last week, I formated this computer and reinstalled OS X 10.5. I updated everything, reinstalled all my applications and replaced my documents. Everything was good for a couple days. I have and HP 1350 all-in-one printer (which HP no long has mac support for that model, so I can only use the scanner as a photocopier, but that's not the issue, it prints fine and I have printed files since the formatting) The printer is connect via USB to my Power Mac and then shared on my home network, wirelessly, with 2 other MacBooks and a 27" iMac. My roommate was trying to print something from his MacBook. In the printer queue on the MacBook, the file would say it was printing, but nothing would actually printer. When I went to the printer settings on the Power Mac, the dialog box said the printer was "in use." I reset the printer, nothing happened. I restarted the Power Mac, properly, and now the computer wont boot past the Apple logo. The spinning gear appears and spins for a minute or 2 and then it will just reboot on its own. It will just keep doing this in a continuous loop.
I've tried to boot into safe mode (holding shift) but it still does the same thing.
I manage to get the CD drive open by booting into open Firmware. I restarted the computer and was able to boot from the Leopard disc. I ran disk utility, and repaired the drive and the permission but everything was ok.
I've unplugged any USB device connect but to no avail.
I really don't want to reinstall Leopard again. it took almost 8 hours to install all the applications (such as Logic, Komplete 5, etc) and I had not setup time machine. There are some document files that I would prefer not to loose, but could deal with the loss.
any suggestions?

Ok, so I reinstalled Leopard, all my documents were in the "Previous Systems" folder, and the applications where present. I went to Software Updates to download all the need updates, which included 10.5.8, itunes, security fixes, etc. It notified my that I would have to restart. I click ok, everything was logged out and the updates started installing. As the computer restarted itself after the updates, i had the same issue again, where it would go to the Apple logo and then restart itself. The second time around, it just froze and the warning "You need to restart your computer" with the power logo in the background came up. So I manually restarted my computer and everything logged in correctly. I restarted it a couple time to see if I could duplicate the errors but everything keeps working properly. Now I'm kind of scare to restart my computer.
Any suggestions as to why this would be happening? Is this most likely a software issue or a hardware issue? This never happened before I formatted last week. The last time I formatted the computer prior to that was less than a year ago.

G5 wont boot from installation disk?

Any suggestions for a G5 that wont boot from the installation CD? Regular starts fail at the grey screen with the apple logo. I've re-set PRAM and SMU, and replaced the battery. G5 passed the Disk Utility tests and the hardware test run over firewire from a PowerBook. I've tried booting from the CD while holding down the various keys. Runs fine in terminal mode so I've saved all my files. Not sure where to go from here. Any help would be appreciated.

Hi choriocapillaris, and a warm welcome to the forums!
Can we assume it booted from this Install Disc before, or could this be an Install Disc from another Mac?
If it is the right Disc, put it in the PB, boot the PB into Target mode...
http://docs.info.apple.com/article.html?artnum=58583
Boot the G5 with the Option key held down & see if the Install Disc in the PB eventually shows up as a boot choice for the G5.

Wont boot on 10.6.3 disc
