trouble boot prob #4

[patrick weaver]

So I ran that booting problem #4. and I thought I solved it once by replacing the mbr. but then I tried it again and I may have typo'd and sucked the bad code down on to my rescue disk.(?!) If that's the problem, I can fix it, i guess but I am wondering if I am up the wrong tree. should I be doing the root'n'boot differently in the grub.conf?? If someone has the the steps-by=steps for boot #4 I would love to see it just to make sure everything is ok with my trouble machine.

Hi Patrick,

I need to take a closer look at this to better understand. I'll be in the CIS Lab late this afternoon (around 4:30) and can take a look if you are around.

Here what I would do.

I would boot up using the rescue disk. In the rescue disk foulder there is a mbr theat you can use to copy it down to the machine.

The command is to restores the boot code portion of the MBR from the file mbr:
dd if=mbr of=/dev/hda bs=1 count=446

Backs up the master boot record to the file mbr:
dd if=/dev/hda of=mbr bs=512 count=1

Try to go back a revert to the snapshot and try that for that VM. Then redo the prob #4 over.
