Comment 5 for bug 156476

You asked if the partition table was changed between 7.04 and 7.10. The
answer is yes and no. The sequence of events was as follows.

1. -- 7.04 installed.
2. -- Created "shared" extended partition between "NTFS" and "Ubuntu
partitions using "Partition Magic" program to shrink "NTFS" to create
room.
3. -- GRUB totally failed to work.
4. -- Modified menu.lst to reflect new partition numbers and reinstalled
GRUB from the grub diskette. GRUB now worked. Partition numbers were
now: 1-Windows XP, 3-UBUNTU.
5. -- Installed 7,10.
6. -- Windows booted ok but UBUNTU didn't. menu.lst partition numbers
were 1-Windows XP, 4-UBUNTU. Install had apparently changed partition
numbers.
7. -- Ran GRUB diskette find function. It identified UBUNTU as
partition 5. This was the GRUB diskette I created from the 7.04
release!
8. -- Updated menu.lst to show UBUNTU as partition 5. Every thing
worked. I did not reinstall GRUB, so the installed GRUB should be the
one installed by 7.10, I presume.
