Hello,
I am running Ubuntu 10.04 Lucid Lynx and Windows XP in GRUB2 based double boot on a Dell Vostro notebook.
For historical reasons I had two separate NTFS data partitions:
/dev/sda1 fat16 DellUtility 39MB
/dev/sda2 ntfs XP 24GB boot
/dev/sda4 ntfs data-1 22GB
/dev/sda3 extended 421GB
/dev/sda5 ntfs data-2 395GB
/dev/sda6 ext3 /home 8GB
/dev/sda7 ext3 / 13GB
/dev/sda8 linux-swap 4GB
In preparation for updating to 13.04 (for another 3 years) I wanted to put all my data in a single primary partition. So I backed up all my data and deleted /dev/sda5, but the partition names changed as follows:
/dev/sda1 fat16 DellUtility 39MB
/dev/sda2 ntfs XP 24GB boot
/dev/sda4 ntfs data-1 22GB
/dev/sda3 extended 421GB
unallocated 395GB
/dev/sda5 ext3 /home 8GB
/dev/sda6 ext3 / 13GB
/dev/sda7 linux-swap 4GB
My idea had been to decrease the size of the extended partition to hold only the Ubuntu files, increase the data-1 primary partition according, and copy in the data which had been in data-2. [I guess I should have decreased to the smallest possible size without deleting it, but now I can't get back to the original configuration, when I create a new logical partition in the unallocated space it is called /dev/sda8.]
When booting failed with this new configuration, I modified fstab to use the right device names for mounting the Ubuntu files (/dev/sda5 instead of /dev/sda6, etc.), but I still can't boot: no GRUB menu, just "Error : unknown file system. Grub rescue>".
I tried the Boot Repair disk, no help, what should I do? Thanks and best regards, John
