G'day Mates, (Karl, NoOp, Goh Lip & Tom (hope I haven't missed anyone))

My name is Noel and I am an Aussie so my English is fine.

You guys are great. Wow you seem to be incredibly busy answering everyone, I don't
knowhow you do it. Very Impressive!!!

Thanks for the help. Sorry it's taken so long, I tried to boot g-parted from a USB
with no success. Had to buy a USB DVD ROM to boot clonezilla so I could image my
hard drive, success.

I'm not sure what do try first,

I am using wubi because the boot.ini has it as the option for Ubuntu.
This was not supposed to be. I screwed up my first boot menu so tried to restore it
from a LiveCD and it looks like I'm running this version of Linux from inside
Windows (I think?) My actual Ubunt 10.10 partition must be there because I'm
missing that much disc space.

----------------------------------------------------------------------
so I ran this,

noel@ubuntu:~$ grub-install -v
loop: can't open device /dev/loop0: Permission denied
grub-install (GNU GRUB 1.98-1ubuntu5)
noel@ubuntu:~$ sudo grub-install -v
[sudo] password for noel:
grub-install (GNU GRUB 1.98-1ubuntu5)
noel@ubuntu:~$ sudo grub-install /dev/sda
Installation finished. No error reported.

I'm not sure what exactly I'm supposed to do now.
But I'm hopeful.

grub4dos is chainloading grub2. Please post xp's boot.ini and

grub4dos' menu.lst, as well as the 10_linux and 30-os-prober sections

of Ubuntu's grub.cfg.

I don't see an ext4 partition in your fdisk output and / is associated

with /dev/loop0 in your df output. Are you using Wubi?
