Installing Xubuntu on external usb hard drive
« on: February 09, 2012, 07:06:45 PM »
I have windows XP and I installed xubuntu 11.04 onto an external usb hard drive (I installed from a USB live system)

When I try to boot it i get this message
Code: [Select]
Unknown filesystem
grub rescue >
Here is my grub.cfg:

I have a swap partition,a boot partition and a root partition set up for xubuntu.
I have tried changing all the hd1 entries in grub.cfg to /dev/sda and /dev/sdb and /dev/sdc, doesn't work.
In the grub rescue > bit, i type ls (hd0) it says unknown filesystem
also tried (hd1) same result.
Can anyone help?
