dual boot fails after upgrade, new cds

[cbarr101]

I installed a set of upgrade CDs, 3 of 'em, RedHat ..
Somehow I disabled Dual Boot ..
grub is the loader .. the config file doesn't look "bad" at first glance
/boot/grub.conf
I think is the filename.

I could re-run the 3 CDs ..

All ideas appreciated ..

What do you mean that you "disabled" dual boot? What is the other system that you want to boot, and on what partition do you have it. Can you post your grub.conf file?

To clarify:
Dual-boot PC:
- WinME (nearly same as Win98 SE)
- Linux - current RedHat

with grub loader

I configured this for "dual boot" - a prompt page offered
Linux
MS-DOS
and after a few secs booted the default

Now, it skips that and displays the
boot:
prompt
where I can't succeed entering "msdos" or dos, or anything but ENTER.

Grub file:
NOTE: the pc has 2 ata disks
a: dos
b: linux
e.g.
mount -t vfat /dev/hda1 /mnt/c_hdd -o user,rw,exec,uid=500

mounts the MS-DOS (fat32) disk ..

Can you describe exactly what happens when you boot your computer? The way you described it as the "boot: " prompt made it sound more like LILO than GRUB. Also, try running "grub-install /dev/hda" as root and see if that fixes the problem.

Also, does your grub.conf really look like that, or did you just accidently paste twice? I'm asking since everything's duplicated.
