how to fix grub.error 17?

[hackem]

I upgraded to 9.10 a few weeks ago. after that, my box was running slower then before.
and pitfall is somehow full of log file in /var/log folder. so I have to cd /var/log && rm * rf (rm * is very very bad habit)

today I startup my computer, it say something like "filesystem check field" and run into a maintain-shell. so I stupid just fsck /var. it prompt me something and I just always y.......
restart, it appearer.

grub loading, please wait....

so I use my 8.04 livecd .
sudo grub
-----
grub> find /boot/grub/stage1
find /boot/grub/stage1

Error 15: File not found

If /boot partition is separated, please try
sudo grub
grub>find /grub/stage1
.....


or you use 9.04 livecd and try.

[hackem]

grub> find /grub/stage1
find /grub/stage1

Error 15: File not found
========
doesn't work .
I wonder if I delete the /boot partition.........
whatever I type , it just didn't match anything.

[smallapple]

You can mount the /boot partition or root partition and check the files if exist or not.
If all files exist, try 9.04 livecd.

ubuntu@ubuntu:/media$ sudo mkdir bb
ubuntu@ubuntu:/media$ sudo mount /dev/sda1 /media/bb
mount: you must specify the filesystem type
ubuntu@ubuntu:/media$ sudo mount -t ext3 /dev/sda1 /media/bb
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

------------
actually, I doing so.
but doesn't know the type

[smallapple]

What is the original installed system? 8.04 or 9.04?
The fs type is ext3 or ext4?
