View Full Version : [ubuntu] Help creating a boot partition

April 27th, 2010, 07:15 AM
Iīve decided to create a new thread because my old one had become rather complicated and now had a misleading title.

I have a laptop with Windows XP and because of a few programs I want to keep it on and dual boot with Ubuntu. I have created a boot partition at the beginning of the harddisk because I had broken the 137gb and canīt keep Ubuntu at the end and still make it bootable.

The separate boot partition is at the beginning of the disk and mounted as /boot in the installation.

The system still canīt boot into Ubuntu, but at least grub shows up with a decent menu and I can choose Windows. When I try to choose Ubuntu it says that it canīt find the specific drive. The UUID is the same as the boot partition

So what should I do now ? Should I change fstab and move some files to the boot partition ? Iīd rather not move the entire Ubuntu partition to the front.

Here is my boot info script

I would test removing the entire search line.

From the grub menu press e for edit and move down to the search line and delete the entire line, then try booting.

It worked ! Thank you :)

Now I only have to find out how to change the line in grub permanently.

April 27th, 2010, 11:26 PM
All done. I just followed this thread :)

this has info:


I just tend to create my own entries and put them into 40_custom and turn off some of the auto searching that grub does. But I think the above is a better way.
