ditchmagnet Posted January 30, 2009 Share Posted January 30, 2009 My osx86 was working better than ever up to this point. I wanted to turn on, iMovie, i think it was, and it said I needed a newer quicktime, so i opened up quicktime and went to update, which launched software update. I unchecked everything except for the available quicktime update, installed and rebooted, but now it is staying on the gray screen for a long time, then rebooting the computer. What should I do to troubleshoot this? Also, how do you boot with verbose or into single user mode with osx86? I have tried holding: ctrl-s, and alt-s and windows key-s but none work, and same with -v option. I tried on usb keyboard, and ps2 keyboard. should i be pressing the keys after i see "loading darwin" or before? I cannot get either to work. thanks Link to comment https://www.insanelymac.com/forum/topic/150285-unable-to-boot-after-quicktime-update/ Share on other sites More sharing options...
ditchmagnet Posted January 30, 2009 Author Share Posted January 30, 2009 Also, I have booted from JAS 10.5 client/server disc and ran disk utility. When I try to repair the volume, it says it stops because of errors. So since I cannot get into single user mode, is there a way to run fsck on my leopard disk from the terminal on the install disc? So how do i switch the working directory to run fsck?

ditchmagnet Posted January 31, 2009 Author Share Posted January 31, 2009 ok, from the JAS install disk, i opened terminal and rand diskutil list my leopard install is on /dev/disk0s1 I ran fsck -f -y /dev/disk0s1 It says: BAD SUPER BLOCK: MAGIC NUMBER WRONG LOOK FOR ALTERNATE SUPERBLOCKS? yes SEARCH FOR SUPER-BLOCKS FAILED. YOU MUST USE THE -b OPTION TO FSCK TO SPECIFIY THE LOCATION OF AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION so then I run: fsck -f -y -b /dev/disk0s1 and it says: fsck: -b option requires a number ---------------------------------------------- Ok, so I've got this far, what number should I use?

ditchmagnet Posted January 31, 2009 Author Share Posted January 31, 2009 ok, i had to run fsck_hfs /dev/disk0s1 and it would run correctly with -fr, or -rd, or whatever, but I am still getting errors, and it cannot finish. fails with error 7, whatever that is. so I still dont know what to do, and I still cannot boot. I guess I will have to install onto another disk and grab my data. if I save the extentions folder from my original drive, and copy that into the new one, will that make all the new kexts i have installed work?
