Hello to all. This will be my first post. I need some advice on what to do with a hard drive.

I have a corrupt kernel file on a hard drive. The drive has been scanned several times (I slaved it on another pc and scanned with AVG) and appears to be virus free. All the data on the drive is intact but, for obvious reasons, the drive still wont boot.

I need to get the drive bootable again. I was going to run fixmbr on it in the recovery console but stopped after a warning message that said the following:

"This computer appears to have a non-standard or invalid master boot record.

FIXMBR may damage your partition tables if you proceed.

This could cause all the partitions on the current hard disk to become inaccessible.

If you are not having problems accessing your drive, do not continue."

How much of a risk I would be taking by running fixmbr?
