linux will not boot, boot to grub prompt

my redhat 9 will not boot. We had a power failure and when the power came back, my redhat linux will not boot.

The machine come up to grub prompt.

I tried the following from grub prompt

root (hd0, then press tab key

partition num:0 filesystem type unknown, partition type 0x83
partition num:1 filesystem type is ext2fs, partition type 0x83
partition num:2 filesystem type is ext2fs, partition type 0x83
partition num:3 filesystem type is ext2fs, partition type 0x83
partition num:4 filesystem type is ext2fs, partition type 0x83
partition num:5 filesystem type is ext2fs, partition type 0x83
partition num:6 filesystem type unknown, partition type 0x83
partition num:7 filesystem type is ext2fs, partition type 0x83
partition num:8 filesystem type is ext2fs, partition type 0x83

my boot partition is on 0
so I issued root (hd0,0)

received the error message filesystem type unknown, partition type 0x83

setup (hd0)
checking if /boot/grub/stage1 exist ... no
checking if /grub/stage1 exist ...no

Also try

configfile /boot/grub/grub.conf
Error 15: file not found

configfile /grub/grub.conf
Error 15: file not found

grub> find /boot/vmlinuz
Error 15: file not found

grub> find /boot/initrd.gz
Error 15: file not found

Finally, I tried copy stage1 file and stage2 from an identical machine
to floppy disk then

grub>root (fd0)
error filesystem type unknown, using whole disk
grub>setup (fd0)
error 17, cannot mount selected parttion
grub>quit

can you help, please.
