First it gets by the part where it wants delete for bios, then control-s for raid utility.

Then it gives a long list of devices. It stops. Grub doesn't seem to come up at all.


A long list of devices. I suppose this is your BIOS still running.

I'd guess you don't have a valid MBR, perhaps nothing written to it
at all. Do you have your rescue CDROM? Try booting from that, and
hex dumping your MBR. Also, can you provide us with what fdisk -l
has to say?


The sad truth is, I don't know how to dump the hex MBR. If someone tells me how, I will do it.

No problem. Everybody's ignorant, just about different things.

Use dd to copy the MBR out. Then use od to display it as hex.
You must be root to do the first part.

# dd bs=512 count=1 if=/dev/hda of=/path/to/your/file

should do it. Er, you are trying to boot from /dev/hda?

the fdisk -l has multi screens full of information except I think you want me to tell you that all devices except md0 and md1 have a * showing that they are bootable.

I'm sorry, I don't recognize "md0" and "md1". And I certainly don't
expect screens full of information. My machine looks like this:

# fdisk -l

Disk /dev/hda: 40.0 GB, 40020664320 bytes

How do I make a grub floppy?


http://www.gnu.org/software/grub/grub-faq.en.html#q4


I made a floppy and When I boot the floppy clicks and makes a tiny grind, so it is trying, but sadly, the device listing in the bios stays on the screen with no error message. Here is the menu.lst on the floppy.

Hmm. Do you have your machine enabled for floppy boot?

It was originally copied from the offending machine using the rescu cd and I then following the instructions in the link to make a floppy which worked except that when it reached the quit, it said file not found. I

I'm sorry, I can't parse "except that when it reached the quit, it
said file not found"

I'm sorry, but I need to leave for the weekend and very soon. Maybe
someone else will pick up this ball...

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
