about rescue mode

Hi,
I meet a big trouble!

because i wanna update my linux 2.40 to 2.6.7-bk, I modify my grub.conf and fstab to solve the kernel panic problem like following list:

modify fstab to£º

/dev/hda8 / ext3 defaults 1 1
/dev/hda7 /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda9 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

modify grub to£º
title Red Hat Linux (2.6.7-bk6)
root (hd0,6)
kernel /vmlinuz-2.6.7-bk6 ro root=/dev/hda8
initrd /initrd-2.6.7-bk6.img

but after that, I can't enter 2.6.7 ,even 2.40 either!

now I try to enter the rescue mode to re-modify the system file grub.conf and fstab, but i didn't find them!

Does anybody be so kind tell me what shall i do then? how to solve this problem.

following list is the information before i modify my file

this is fdisk list

when you enter rescue mode, type run
mount
by itself, and it will show you what is mounted where.

i try it, but no use, although i can't remember what it exactly mentioned

then i guess you'll have to mount the partitions yourself. make mountpoints in /mnt and mount away.
mkdir /mnt/hda7
mount /dev/hda7 /mnt/hda7
cd /mnt/hda7/etc
cat fstab
and such
