Grub wont boot after a kernel upgrade

[EzMe]

Hi all,

 

I've got a weird problem with my gentooserver after upgrading my kernel with genkernel. For some reason it wont boot anymore. When i try to boot it says:

 

Code:

Grub loading Stage1.5 Grub loading, please wait...

 

Then grub hangs up indefinetely.

 

So, i booted from a gentoo liveCD, setted up my network and sshd and logged into it. After that:

 

Code:

swapon /dev/sda2 mount /dev/sda3 /mnt/gentoo mount /dev/sda1 /mnt/gentoo/boot mount -t proc none /mnt/gentoo/proc mount -o bind /dev /mnt/gentoo/dev cp -L /etc/resolv.conf /mnt/gentoo/etc/resolv.conf

 

then chroot to the system

 

Code:

chroot /mnt/gentoo /bin/bash env-update source /etc/profile export PS1="(chroot) $PS1"

 

After that i updated /etc/mtab sinds Grub needs this:

 

Code:

cp /proc/mounts /etc/mtab

 

My partition table:

 

Code:

(chroot) livecd / # fdisk -l Disk /dev/sda: 33.8 GB, 33820286976 bytes 255 heads, 63 sectors/track, 4111 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x277b277a Device Boot Start End Blocks Id System /dev/sda1 * 1 5 40131 83 Linux /dev/sda2 6 37 257040 82 Linux swap / Solaris /dev/sda3 38 4111 32724405 83 Linux Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table (chroot) livecd / #

 

After that i tried reinstalling Grub:

 

Code:

(chroot) livecd grub # grub-install /dev/sda Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Unknown partition table signature Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'. (fd0) /dev/fd0 (hd0) /dev/sda (hd1) /dev/sdb (chroot) livecd grub #

 

 

(/boot is on sda1)

 

Code:

grub grub> root (hd0,0) Filesystem type is ext2fs, partition type 0x83 grub> setup (hd0) Checking if "/boot/grub/stage1" exists... yes Checking if "/boot/grub/stage2" exists... yes Checking if "/boot/grub/e2fs_stage1_5" exists... yes Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 17 sectors are embedded. succeeded Running "install /boot/grub/stage1 (hd0) (hd0)1+17 p (hd0,0)/boot/grub/stage2 /boot/grub/menu.lst"... succeeded Done. grub> quit

 

I wiped my MBR to make sure that the new info get's installed:

 

Code:

dd if=/dev/zero of=/dev/sda bs=446 count=1

 

But still the same problem.

 

Code:

(chroot) livecd / # grub --version grub (GNU GRUB 0.97)

 

Code:

(chroot) livecd / # fdisk -l Disk /dev/sda: 33.8 GB, 33820286976 bytes 255 heads, 63 sectors/track, 4111 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 * 1 5 40131 83 Linux /dev/sda2 6 37 257040 82 Linux swap / Solaris /dev/sda3 38 4111 32724405 83 Linux Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table

Can you interrupt the grub boot sequence? Or don't you get as far as the splash screen?
