- You're gonna scream some more before you finish reading this post. You don't
- have to blow away the entire disk to get rid of the Coherent boot record.
- If you have MS-DOS 5.0, you only have to type the following:
-
- fdisk /mbr
-
- You should see a second or two of disk activity and that's it. You don't even
- have to reboot if you don't want to.
-
- The /mbr is an undocumented flag added to fdisk in 5.0 which will rebuild your
- Master Boot Record (note the capitalized letters) for you. This will expunge
- the MWC boot record, 386bsd disk labels (I think: a friend of mine was having
- trouble with his SCSI drive because of a stale 386bsd disklabel and this fixed
- it), plus it's also great for killing boot-sector viruses. No, really.
-
- I kinda doubt that the old boot record is the source of the problems you
- seem to be having, but keep this infor around for future reference. Better
- late than never I guess.
