Well, here goes... A few weeks ago software update said a new version of OS 10.4.x.x was available, so I started to install it on my imac ppc with isight, purchased in 2005. Then I got an error message saying it didn't install so the package or whatever was sent to the trash bin. Didn't think anything of it, later shut off computer and then later turned it on. It would chime, then get to the grey apple screen with the startup wheel.
I then did several things:
removed all peripherals
tried to do a "safe boot" where it would just get stuck at "could not establish the default connection to the WindowServer"
reset nvram / pram
ran "fsck" in single-user mode, it found one problem, ran it again, said the HD appeared to be working normally
rebooted, still just got the turning startup wheel grey screen
then rebooted in again in single-user mode and ran the following (found on a macosx.com thread):
/sbin/mount -uw /
cd /Library/Preferences
rm com.apple.loginwindow.plist
rm com.apple.windowserver.plist
cd /Library/Caches
rm -r *
cd /System/Library
rm Extensions.kextcache
cd /System/Library/Caches
rm -r *
reboot
It rebooted, and then gave me this panic message:
panic(cpu 0 caller 0x002E1EC4): Unable to find driver for this platform: "PowerMac12,1",

panic: We are hanging here...
You need to restart your computer. Hold down the Power button for several seconds or press the Restart button.
I then started in open firmware and did:
reset-nvram
reset-all
It rebooted and still gave the same panic/you must restart message.
I cannot find my original install discs (moved twice, in a box somewhere).
Is there anything I can try? Should I just take out the hard drive and mount it on another mac (i have a 2.16 GHz intel core 2 duo 10.4.11 macbook) if that's possible?
Did I do something very terrible to the hard drive when in single-user mode? Help please!
