purchased second hand. I'll have to see if I can find any discs.
I got the following info from the model #, not sure if that helps any.
If that didn't work, then boot your Mac into Safe Mode. Turn off your Mac. Turn it back on and immediately hold down the Shift key on your Keyboard. Release the Shift key when you see the gray Apple and progress indicator. Let the Mac boot up to Safe Mode.
Reset pram resulted in same blue screen.
I started into safe mode, however, the screen has been on the apple logo loading screen for almost 10 minutes now. Not sure how long it should take.
OK, I'll leave it running. And I'll keep looking for those discs.
If Safe Mode didn’t work, then we can run Disk Utility from Single User Mode. Follow the steps below to run Disk Utility in Single User Mode. Turn your Mac off. Turn it back on and this time hold down the Command (Apple) key and the S keys at the same time. This will boot your Mac into Single User Mode (black screen with white letters). Then type the following commands... /sbin/fsck -fy (note the space between fsck and -fy) If you can't run /sbin/fsck -fy then type only fsk - fy Hit return and the disk utility should run and let it finish. When it finishes and there is no error, then type reboot and hit return. Let the Mac boot up. If you got any errors from Disk Utility, please let me know.
Safe boot did not work (after 3 hrs).
Single User Mode came back with a folder with question mark. I could hear the hard drive reading for a while and then the icon appeared on the screen.
I haven't found cd's yet, but I've got one more spot to look.
Can't find cd's so I'll have to pick some up. Can I get any version of Snow Leopard to work with this iMac? Just let me know what version I need and I'll buy it and try it out. I guess I'll need it either way- to repair the hard drive or reinstall OS onto a new one.
I downloaded Snow Leopard 10.6.3. Is there a way to put it on a usb drive and boot from there? I know there are some programs to burn dmg in windows, but it can sometimes be buggy.
I got a Snow Leopard disc. 10.6.3 I hold down "C" to boot from cd, but the screen is just white for a while.
I then get the "no" symbol with a status bar below.
The disc was burned on a DL DVD, will the mac read a DL disc? I'm assuming it will since the program itself is around 5.5gb.
Will it recognize a usb dvd drive? I can try that in case the drive inside the mac is faulty.
Anything else to try?
I used TransMac to create a bootable usb stick. I used the option key, but eventually get the "no" symbol again.
Even if it doesn't recognize one drive, shouldn't it at least display the drives I can boot from? Should I try an earlier version of Snow Leopard?
If the hard drive is bad, would this stuff still work or will I have to replace the drive first?
I have a Snow Leopard install that works now.
My next issue is that at installation, I get a warning sign that states OS cannot be installed b/c the partition is not correct for mac.
I used Disk Utility to erase the volume and set as Mac OS Extended. I restarted install and I get same warning message.
How do I format this drive to be able to use on mac? Are not all sata drives compatible?
This drive is a used one pulled from a windows desktop. It's a good drive (tested with crystal disk info).
I go through the steps to erase the drive, but still get error message.
No luck. I used the partition tab and I still got error message upon entering installation.
Something is up with this system.
I've got a used drive that I pulled from another windows computer that I know was good.
After erasing the drive and creating a mac partition, I get the same error about not being able to install on this drive.
Same as the 3 pictures from previous post.
Think I got it.
The GUID Partition Scheme was not in a pop-up menu, but below the white box where partitions are labeled in the button labeled "options".
Once I changed from MBR to GUID, it seems to be installing.
It seems that the power supply was also bad, as it quit powering on.
Here's where I'm at:
I ordered a new power supply and after install the mac booted up. I shutdown, unplugged power, grounded myself and put everything back together. Upon restart, I got the screen with ? folder flashing. I put my install disk back in and booted to it and reinstalled the OS. Install went fine and I was able to use the OS. I shutdown and turned back on- got the folder again. I again booted to install disk and used disk utility. Using verify and repair disk, they both said that drive appears to be ok. Tried to boot into safe mode and either it won't or not recognizing keyboard. The hard drive is new/tested.
When I install the os, I can use it fine. But it's when the unit is powered down and restarted that it cannot boot. Could there be something wrong with a boot order?
Couldn't get anything to come up that way.
However, I reset the pram (let it cycle twice) and then it booted into os with no problems. I turned it off and back on, and got the ? folder again. Resetting the pram did get the os to come up. Hope that helps figure this out.
Can you take out the RAMs and then reseat them ?
I reseated the ram with the same result.
When I got into system preferences it looked like the network was selected to boot from. Changed to HD and selected restart and it booted back to HD. After power down, however, it started back up to the ? folder. Seems like it's not remembering where to boot from.
