Disk Utility repair failure: You need to restart your computer. Hold down...

Question

While trying to backup my macbook pro (running 10.5.8 leopard). I kept getting the gray window that forced me to shut down my computer. After some research, I conluded that I needed to check my HDD for damage. I ran the Verify Disk option (Repair Disk option was not yet "clickable"), and it says
First Aid Failed
stopped verifying HD because the following error occured:
Filesystem verify or repair failed.
In the text box below that, it says
"(It should be 771886 instead of 771889)
Invalid volume directory count
(It should be 148275 instead of 148272)
The volume Macintosh HD needes to be repaired.
ERROR: Filesystem verify or repair failed."
I then tried the Repair Disk Permissions option and it came up with three difference
Library/application support/proapps
System/Library/privateframeworks/browserkit.framework
System/Library/privateframeworks/prokit.framework
(I can give more information on these three if that would help at al)
In the Verify Disk error, it says that it needs to be repaired, but the repair disk option is still not clickable. I don't know what to do from here. Is there someone more tech savvy than I who can help?

Answer 1

You cannot do rewpairs from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair:

Once that is complete reboot again from your usual start-up disk.
