View Full Version : [ubuntu] Ubuntu 11.04 installed OK and now will not boot up

The original installation went fine and worked OK for 2 weeks.
I added a third user and it crashed, leaving a distorted locked screen.
Now it will not boot up at all - just the disk information and the hardware setup screens from the machine but no grub screens or operating system load.
I have booted from a live cd which enables me to see all the files on the hard drive in both windows 7 and ubuntu partitions so the problem seems to be the booting.

This is the output from boot_info_script.sh from the file RESULTS.TXT

Can anyone help with commands to restore the booting (GRUB?)

This looks wrong.

=> Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and looks
for (,msdos5)/boot/grub on this drive.


Sector 1 is obviously not the right place to look for files which are on /dev/sda5. Try reinstalling Grub from the live cd.
https://help.ubuntu.com/community/Grub2/#Reinstalling%20GRUB2

If the GUI tool works, good, and if not (too many options there), following are the commands to use:


sudo mount /dev/sda5 /mnt

sudo grub-install --root-directory=/mnt /dev/sda

Thank you. I used the link to boot-repair and it fixed it on the first pass. Many thanks for your help.
