Imac 2011 27" won't boot / safe mode / install disc / bootcamp

I've been having an ongoing problem with my computerwhere it randomly crashes. my first visit with the Apple Store resulted in a replacement of the video card. that only fixed the issue for less than a month. during the second visit they did a full hardware test and deduced that the third party RAM was defective.I was also advised that the OS would need to be reinstalled. when I got the computer back I was able to boot up the system without issues, but before I could back anything up it crashed again. Now I cannot restart the computer past the spinning wheel I get a white screen. I cannot boot the computer into safe mode either. I have the original installation disk but it also hangs after the spinning wheel. I have also tried loading up boot camp and that also hangs after the Windows screen. I was however able to load up Windows in Safe Mode. does anyone know what is going on here?

Try restarting while holding down the Option key. Theoretically, that will prompt the Startup Manager window where you can select the startup disk. If the startup disk is not available, then it's probably time for another trip to the Apple Store.
Did you by chance purchase AppleCare ??

Intel iMac will not turn on. Won't boot up from install disc either.

The last couple of weeks I have been noticing lag, freeze and graphical issues with my Intel iMac -- ever since I installed a video game called Warcraft 3. My computer's specs are way beyond the recommended specs of the game (it was released in 2002) but even when playing the game I would have graphic and freeze issues. It would get to the point where I would have to power off my computer and power it back on to get out of the freeze.
Tonight when it froze my computer, my whole screen was given a "digital green" tint. I can't figure out any other way to describe it. I powered the computer off, turned it back on and the usual Apple that pops up when the computer starts up had the same "digital green" lines through it. After that it goes to a grey screen and sits there.
I put in the install discs that came with the computer and powered it back on -- same scenario would play out. It was like it wasn't reading the discs. I turned it off again and held down "Option" when powering it on and it asked me what I wanted to boot from: the hard drive or the install disc (the green tint was gone). I chose hard drive and my computer booted up like normal finally, but once the desktop screen finished loading, the whole screen turned green and froze again. I powered down, turned it on with "option" again and chose to boot from the install disc (now the hard drive and install disc labels had the green tint too). Nothing happened. The computer went right back to a grey screen and stayed there.
Any ideas what the problem could be and how I might fix this?

Hello fallingisfunny
As described in the link below, run the Apple Hardware Test a and see if it detects a hardware issue! If a hardware problem is found then you will need to take the iMac in for service!
http://support.apple.com/kb/HT1509
Apple support will probably have you do an *Archive and Install* or *Erase and Install* from the OS X Install Disk. If you have everything backed-up, you might give that a run as per the article in the next link!

IMac won't boot from OS install disc

Hello. I'm using a refurbished 2010 - 2011 iMac running Snow Leopard, which did not come with the original install disc. Just purchased from Apple, an OS (Snow Leopard) Install Disc specific for my model iMac but my machine will not boot from it.
I've tried booting from the disc holding down the "C" key and it tries to start up but all I see is the grey Apple logo, no spinning gear and it just hangs there. I've also tried holding down the Option key and selecting the Install disc from the start-up choices that display but the same thing happens. Any ideas, anyone?

Did you call Apple and ask for replacement disks (giving them your serial number)?
If not, and if you purchased the retail version at the Apple store online, then you may have a version that is older than what yours came with. And, macs cannot boot from an OS older than what they came with. I believe the latest retail version is 10.6.3 and yours might have had 10.6.4 or higher. You might want to check on your model to get the exact OS version; you may need to call Apple and request replacement disks.

Black MacBook won't boot off OS Install Disc!

Hi all,
Just wanting to help out a friend here (who is not really knowledgeable in the area of fixing Mac faults)
The product in question is a Black MacBook (MacBook4,1) - 2.4Ghz, 2GB RAM. He had previously had the factory standard 250GB installed in the Macbook.
The MacBook had functioned normally until one day it had crashed. Upon a hard reset (ie using the Physical Power Button on the MacBook), the OS would not boot - a grey screen would appear with an Apple Logo, fans blowing at full speed. Diagnostics (AHT) using the Applications Disc would not boot either.
The following have been attemped, with no success in booting to the OS Disc:
* Clearing the PRAM
* Clearing the NVRAM
* Booting the OS Disc from another MacBook connected via Firewire (ie Target Disc Mode)
* Reseating the RAM Modules
* Using only one RAM Module
* Using a different (working 80GB) Hard Drive
* Repartitioning the 'different' Hard Drive (using a GPT Scheme / MBR Scheme)
* Booting into Single User Mode (Command-S) - would hang at the Grey Screen on boot
* Booting into Verbose Mode (Command-V) which hangs at 'appleintelcpupowermanagementclient'
Unfortunately the product is now out of the window of the standard 12 month AppleCare warranty provided as standard on MacBooks. I am now stuck in a rut, as I did promise him that 'it will be fixed'!
Would appreciate your thoughts.

IMac 8,1 won't boot after Lion Install.

Hey guys,
I have an iMac8,1 with a 2.4GHz Intel Core 2 Duo that I just installed Lion on.
It previously had Leopard on it, but after shutting it down to boot from the USB stick that I had made on my MacBook, I pressed alt to show the device selection menu. There were no options except EFI boot with an orange drive, which I took for the Lion stick that I had made. Installing Lion went without a hitch. I formatted the drive that Leopard was on and did a clean install. After it was finished, I set up Lion and set up a Boot Camp partition so that I could install Windows 7 side by side with it. I booted into the device selection menu (holding down alt/option while booting) and it showed me a completely blank screen. No Macintosh HD, no EFI boot, no Windows DVD, nothing.
I put the flash drive back into the machine, and kept restarting it and seeing the same result, until all of a sudden it decided to finally start, and I saw the Apple logo. After a while, though, it became apparent that it was not booting into OS X Lion on the hard drive, but rather the Lion Install.
I have no idea what to do with this machine. It was running extremely slowly before I started trying to fix it, and it didn't make sense to me that a machine with fairly capable specs (I have the same processor and 2GB of RAM on my MacBook and it runs great) would run so catastrophically slowly.
Also, I'm now in Disk Utility running from the Lion USB and it a) sees both partitions and mounts them fine, b) says that "The volume "Macintosh HD" appears to be OK", after Repair Disk c) is unable to fix or verify disk permissions.
I'm at a loss as to what to do. Can anyone help?

If you have backups of all OS X and WIndows data on the internal drive, I suggest you partition it with the default options (GUID partition table, one data partition) while booted from the USB device. Install OS X and test. If you can boot in that configuration, restore your OS X data and then run Boot Camp Assistant, if you wish.
If the above procedure is unsuccessful, the machine has a hardware fault.

IMac G4 800 won't boot

Hi,
My old G4 iMac flat panel won't boot (Spec and OS below). When you turn it on it gets stuck on the grey screen and nothing happens. I've tried holding down shift to get a safe boot but that doesn't work. I've then tried using the OS install disk to access disk utility but that doesn't work. Just the same grey screen. Now you can't use the power button to force it to turn off, you have to switch it off at the mains.
Any help please!
Spec
iMac G4 800 MHZ 767 gigs Ram
OS 10.2.8
Thanks

Hello Again Reelsick Productions!
As I Previously Replied, in your Other Topic;
What size is the Hard Drive, and how much space is available?
How much RAM is installed, and is it original or added?
What peripherals do you have connected? A keyboard, mouse, printer, external drive or modem, router, etc?
What happened between the last time the iMac started successfully, and when it didn't?
Have you made any changes, like upgrading the system, updated or installed any applications or programs, etc?
Have there been any unusual occurences, like freezes, crashes, power outages, etc?
Are you able to startup from the system install disc using John Huber's Startup Manager suggestion to run Repair Disk?
Is the iMac shutdown overnight, or does it run 24/7?
Have you ever run any routine Maintenance procedures?

Imac 7 1 won't boot

My imac 7 1 won't boot up without a cd. When I try to boot it up without a cd it just pops up with a blinking grey folder and a question mark inside the folder. When I boot it up with any cd (mac os x 10.4.10 or mac os x 10.5.4) it boots up and I have to select a language then a message pops up and says "THIS SOFTWARE CANNOT BE INSTALLED ON THIS COMPUTER."... THIS IS THE WEIRDEST THING TO ME: When I hold the power button and option key, I no longer sees MACINTOSH HD, it just shows the blinking grey folder. I said I no longer see Macintosh HD, is because there was a time when it was actually there. Macintosh HD also isn't in my startup disk as it suppose to be. When I use the disk utility on either cd, i actually see Macintosh HD....SOMEONE PLEASE HELP ME, I'M NOT A MAC USER BUT A WINDOWS....I JUST WANTED TO TRY MAC OUT AND SO FAR ITS SO BAD.....

The 7,1 iMac is a mid-2007, 24 inch (can you confirm that's correct?), which came with OS 10.4.10 originally, so you seem to have the correct disks. It also sounds like you are able to boot from a CD successfully, and the fact that you can then see the HD icon is a good sign. It may be that Disk Utility can repair it, I would try that and report what DI tells you.
However, do you have a back up of files from this disk? Before doing anything else you should try to rescue any critical files from it. An external drive would be very useful for this if you don't have one already.
This machine is also user-repairable (I've replaced an internal hard-drive on this machine myself, tricky but not impossible!), or you could have a repair shop do it for several hundred $. Its also the case that you could just buy an external drive, load a new system on it and never replace the internal drive. This would be much cheaper and easier, cost depends on how much space you want and the quality of the drive, but for $100 you could have a much larger drive than what you have currently (probably a 320 or 500MB).

My iMac does not wake from power safe mode

My iMac does not wake from power safe mode when addressed over the network from my Apple TV, until I send a "wake on LAN" command from a utility on my iPad. Is there anyway this can be done directly from Apple TV?

Tons of similar reports all over the web - especially on ATV3 - but no solution, seemingly. Hopefully a software update will fix it one day soon. Sorry.

IMac 400 DV won't boot

My trusty iMac 400 DV won't boot, and it is currently our main email machine. It has 19 GB HD and 3+ GB available, according to Finder. I'm using 10.3.9 with 768 MB RAM. Please send any suggestions ...
Symptoms:
It had been bogging down lately, and making a few clicking sounds plus the usual whirring.
I did Repair Permissions, Onyx clean up recently. Did not help much.
Today I wanted to check hard drive, so I put in G4 install/recover DVD 1 of 2 for 10.3 & restarted with Control key.
It took forever, but only got the bong, then the apple icon, a small colored square, then a blue screen.
Unplugged everything & retried. Could not get DVD out, even with paper clip.
Tried to zap PRAM on startup, but kept Restart message now after a long time.
Have not tried resetting PMU yet. Looks like its a square button by the RAM slot.
Suspect I have an immediate problem due to jammed DVD, then possible HD and PRAM. Do Radio Shack or other local computer stores usually sell the 3.5 V battery?
THANKS IN ADVANCE!!

Hey tom and welcome to Apple discussions,
It had been bogging down lately, and making a few clicking sounds plus the usual whirring.
Sounds like the hard drive going bad.
Today I wanted to check hard drive, so I put in G4 install/recover DVD 1 of 2 for 10.3 & restarted with Control key.
Yah usually it's not going to like that since it's a machine specific disk.
Unplugged everything & retried. Could not get DVD out, even with paper clip.
This way?

Yes but it's $16 vs $5 at OWC. Most likely you'll need a new HD and the proper installer.

24" iMac Can't Boot OS X Install Discs

I have a 24" iMac (A1225). I can boot to non-Apple discs (utilities, Windows) and I can even install Windows without any problems. I can't boot to any OS X Install disc however. I have the original 10.5 discs, they don't boot. I have a 10.7 disc that does the same. It starts to boot and makes encouraging noises for a bit but eventually both discs spin down with the Apple logo and the spinning circle which stops.
Just for shiggles I tried to boot a couple of custom OSx86 discs (10.6.3 and 10.6.6). They both booted to the installer. 10.6.3 started installing (crashed half-way) but started to boot from the HDD after I restarted it (it didn't go anywhere of course, just the Apple logo). 10.6.6 finished installing but wouldn't boot after it restarted.
It seems like there's a hardware issue but the fact that I can boot non-Apple discs and even install Windows without issue makes me doubt that. I have also cleared the PRAM (Option-Command-PR) and ran a quick test in AHT (D) without issues.
Any suggestions on what I can check next?

I can try it again but I think I've left it for more than 10 minutes Also, as I said, the spinner stops and the DVD spins down. Thanks for the reply!

Leopard DVD won't boot after bad install

I ran the leopard installation yesterday and I realized that i needed to do some more work on the drive before i installed, so i clicke cancel and restarted the computer. Now the dvd won't boot. I installed tiger again(came with laptop) and tried doing various other things with the disk. Almost any ntensive use of the disk (booting from it, trying to clone it, etc.) will result in the superdrive powering up and then down repeatedly, sans result. I left the leopard dvd to boot for hours and when it tries it gets to the grey logo and the drive does that power up/down cycle endlessly. I can boot from ubuntu's disk and the tiger disk that came with my computer. The disk mounts to the desktop, btw, and i can browse the files and everything. Apple support was no help.

I've been doing some work with the disk. I did another attempt at creating a dmg from it and got the same result, so I googled the error which led me to a thread on this site with a similar issue. The error was input/output error. They found that it was due to a corrupt file... so I did a cp -r of the disk and it said that a few files did not exist:
cp -r "Mac OS X Install DVD" /Users/mattebooks/Desktop/Leopard
cp: Mac OS X Install DVD/usr/lib/libpython.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libpython2.5.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libpython2.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libruby.1.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libruby.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libtcl.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libtcl8.4.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libtk.dylib: No such file or directory
cp: Mac OS X Install DVD/usr/lib/libtk8.4.dylib: No such file or directory
So I set Finder to show hidden files and went to these files libpython and libpython2.5 are aliases of libpython2 and libpython2 is an alias of a file in a non-existing folder. A little more digging and I find out that the python, ruby, tcl and tk framework folders are all missing, all from the same folder... interesting. Maybe I could add the files in and reburn the disk. My guess is that the loader looks for these files repeatedly. The path to the files is /System/Library/Frameworks/... If anyone could email these to me I could try and rebuild the disk...

Can't boot iBook with install disc

Hi All,
I've inherited an old clamshell iBook that freezes every time I try to boot from the install disc.
The iBook came with 0S9.2 installed and everything seemed to be working OK. I then tried to upgrade it using a retail Jaguar disc and it froze on booting up. Now it won't even load OS9 but instead gives me a blinking folder with a question mark.
When I try to install from the Jaguar boot disc, I get the Apple logo and then it freezes right there. I tried zapping the P-Ram a few times and that didn't fix it. I tried holding Option key when loading and got to the screen where it lists boot options. I chose OS X and it after the logo comes up, it freezes.
Have also tried re-seating and completely removing the RAM. No difference.
When I go into verbose mode I get some kind of kernel panic error freeze and the keyboard won't let me input anything.
I reached the open firmware screen and it says Powerbook2,1 4.1.7f4 so I think that means my firmware is fine for OS X.
I unfortunately don't have access to an OS 9.2 disc so can't boot into that from disc. I think my 9.2 system folder needs to be re-blessed or something like that but have no way to reach it.
Any suggestions?

Ok, well, I believe that in order to re-bless the OS 9 system folder, you need the OS 9 CD. (I'm not an OS 9 expert, but that's what I've seen online).
However, if you install 10.2 (or 10.3) on the computer, it should boot right into it and you don't even "need" OS 9 any more.
I'm starting to think you have a hardware problem of some kind, and the first place to check is the RAM. OS X is more finicky than OS 9 was with RAM, so do you have another memory module you could install to check? Or perhaps another clamshell (like was suggested) to try your RAM in?
Do you have an Apple Hardware test disk? My next suggestion would be to get one and to run the test and see what (if any) hardware is having problems.
And one more thought: if you can boot using the 10.3 disk, try running Disk Utility and repairing your disk a couple of times. Maybe there's a problem in your hard drive.

Mac pro won't read windows 7 install disc?

My 2007 mac pro won't read windows 7 install disc. My macbook reads the disc fine, so it is not a problem with the disc. It is 32-bit. The apple help line suggested firewire connecting the macbook to the macpro and starting the macbook in target disc mode, but other posts I have read have said that this will not solve the issue. Any suggestions?

Could be. I just rebooted and it read the disc. Unfortunately the windows install got interrupted and I had to reboot, and now it wont read the disc again. Is there any other way to install windows 7 to bootcamp, other than from the disc? Can I use FireWire and target disc my MacBook (the MacBook reads the disc just fine)?

Contact Apple (call AppleCare) and for a nominal fee the discs will be replaced. You can do that or purchase Snow Leopard (still availble from Apple for $20) and do an erase and install of OS X making the machine like a new machine.
