URGENT. After upgraded no 10.04 in menu

[vzhen]

I upgraded 9.04 to 9.10 to 10.04.
During the upgrading i chose all "using local .....setting" exp menu.list .....


After upgraded and reboot, it using grub loader 1.5 and only display
-9.04 kernel 2.6.28
-9.04 kernel 2.6.28 recovery
-Windows xp

NO 10.04 at all

If i choose 9.04 kernel 2.6.28 to boot. It hang in startup with black screen (freeze)

What can i do ?

Window XP = no problem

FIXED

1. Boot into the live CD
2. Chroot into the real system:
2.1 Find which partition the real system is installed on with sudo fdisk -l
2.2 Make a directory to mount it at with sudo mkdir -p /mnt/computer
2.3 Change to that directory with cd /mnt/computer/
2.4 Mount it with sudo mount /dev/sda? /mnt/computer/
2.5 Link /dev/ and /proc/ with sudo mount --bind /dev/sda? /mnt/computer/dev/
2.6 sudo mount -- bind /proc/sda? /mnt/computer/proc/
2.7 Change root with sudo chroot /mnt/computer/
3. Update grub2 with update-grub2

OR use

Thanks all the replies

See the comments here. It detected that you had customized your menu.lst and cannot in all cases convert everything.

If sudo update-grub does not work, you will have to manually add new entries for the new kernels.

Hi, Thanks for your reply

Can u show me how to perform this under live cd since i missed the step during upgrade

Using live cd to boot in is the only way i can use.

Thank you

Boot into the live CD
Chroot into the real system:

Find which partition the real system is installed on with sudo fdisk -l
Make a directory to mount it at with sudo mkdir -p /mnt/computer
Change to that directory with cd /mnt/computer/
Mount it with sudo mount /dev/sd?? /mnt/computer/
Link /dev/ and /proc/ with sudo mount -B /dev/ /mnt/computer/dev/ & sudo mount -B /proc/ /mnt/computer/proc/
Change root with sudo chroot /mnt/computer/

Update grub2 with update-grub2


Steps 2.1 & 2.4: If you can't figure out which partition Ubuntu is installed to, then post the results of sudo fdisk -l back here and I'll update the instructions for you.

Thanks again

This is my sudo fdisk -l

Penguin Guy's post is for grub2 and chrooting into it.

I think you can just edit menu.lst from the liveCD. You will have to drill down to /??/boot/grub. I do not remember if /?? is /media and your install or whatever the liveCD adds to the beginning of the mount. You are showing two linux partitions, do you have two installs? You need to edit the correct one that has grub in the MBR.

Copy one of your current entries and update UUIDs and kernel versions to the new ones.

To see UUIDs
sudo blkid

Kernels will be in /boot so you can copy the names.

Sorry about that, I didn't read the original post properly and just assumed that he would be using Grub2.

Hi, This is fixed.
I will re-write the instruction in my 1st posted.
