this is so weird.
the system was okay, then i recompiled kernel.
cp to /boot/, then the next time i restarted, it gives "kernel panic VFS on 37"

here's /etc/fstab:

/dev/hda1 /boot ext3 noauto,noatime 1 1
/dev/hda7 / reiserfs noatime 0 0
/dev/hda5 none swap sw 0 0

/boot/grub/grub.conf:

splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=gentoo
root (hd0,0)
kernel /boot/bzImage-gaming root=/dev/hda7

then afterward i booted the cd, double checked grub.conf, changed the line in fstab to :

/dev/hda1 /boot ext3 noauto,noatime 1 2
/dev/hda7 / reiserfs noatime 0 1
('cause this was the default in the installation guide)

then reinstall grub by :
grub> root (hd0,0)
grub> setup (hd0)

also, there was a boot which is a link to /boot, and i just deleted it 'cause i thought we don't need it. or do we?

now, after reboot, the grub menu doesn't appear, instead give a black screen with "kernel /boot/bzImage-gaming root=/dev/hda7...file not found"

is there anything i can check to fix this problem?
thx

If you copied your kernel to /boot then in your grub it should be

Code: Select all

kernel /bzImage-gaming root=/dev/hda7

The "boot -> ." symlink in /boot is only needed if you want to use the wrong paths in your grub.conf

Try changing grub.conf to this :

Code: Select all

root (hd0,0)
splashimage=/grub/splash.xpm.gz
title=gentoo
kernel /bzImage-gaming root=/dev/hda7

The reason for the symlink is that we don't need to make seperate configuration files regardless of the fact that /boot is a seperate partition or not. You generally don't need it if you know how to edit the bootloader configuration file.

yea since i couldn't use grub, i had to boot from grub floppy,
then execute :
kernel (hd0,0)/bzImage-gaming root=/dev/hda7

it worked instead of :
kernel (hd0,0)/boot/bzImage-gaming root=/dev/hda7
,which gave "file not found".

but in the mid way down, it still gives error.

Code: Select all

.
.
ds: no sockets drivers loaded
XFS: bad magic number
XFS:SB validate failed
kernel panic: VFS: Unable to mount root  fs on 03:07

EDIT
could it be the options in the fstab? i'm not sure what "1 1" or "0 0" means
