Trying to Load Ubuntu 11.04 onto HP Laptop. Failed at reboot

[Peter Fitzpatrick]

Hi Goh Lip

Have tried the commands you suggested. Failed at the insmod command as
follows;

List starts with machine just rebooted: Note that the machine currently has
the 10.04 LTS version installed (or partly so)

Error: out of disk
Grub rescue> set prefix=(hd0,1)/boot/grub
Grub rescue> insmod (hd0,1)/boot/grub/normal.mod
Error: out of disk
Grub rescue> normal
Unknown command 'normal'
Grub rescue> cat (hd0,1)/etc/lsb-release
Unknown command 'cat'
Grub rescue> search -f /boot/grub/grub.cfg
Unknown command 'search'
Grub rescue> search -f vmlinuz
Unknown command 'search'
Grub rescue> ls
(hd0) (hd0,1)
Grub rescue> set
Prefix=(hd0,1)/boot/grub
Root=hd0,1
Grub rescue>

Thanks for the assistance so far. Anything else I can try?

Peter

Peter, unless there are more serious problems in your installation, try 
as follows....

grub rescue> set prefix=(hd0,1)/boot/grub
grub rescue> insmod (hd0,1)/boot/grub/normal.mod
grub rescue> normal

[here you should see a 'normal' grub prompt "grub>" ]
Then .....
grub> set root=(hd0,1)
grub> linux (hd0,1)/vmlinuz root=/dev/sda1 ro
grub> initrd (hd0,1)/initrd.img
grub> boot


When (If) booted up, open a terminal and
sudo grub-install /dev/sda
sudo apt-get update
sudo apt-get upgrade


Regards and good luck - Goh Lip

ps: hopefully do don't need this...
if boot fails at grub-rescue mode, let us know the output...
grub rescue> cat (hd0,1)/etc/lsb-release
grub rescue> search -f /boot/grub/grub.cfg
grub rescue> search -f /vmlinuz
