Hi,

I used LVPM and this guide (http://lubi.sourceforge.net/lvpm.html) to transfer my wubi ubuntu installation to a new partition. The problem I am now having is that I cannot boot into ubuntu because the bootloader is not setup properly. I know this because I was able to boot into ubuntu fine after transferring it to a separate partition.So I uninstalled wubi from windows xp and now I can't boot into ubuntu. I know I installed it properly because setup (hd0,2) is successful. When i enter the boot command it says "Kernel must be loaded before booting". So, if anyone can help me with how to boot into ubuntu using command line and then how to fix the bootloader, I will be very grateful.

if you are using grub2:

insmod ext2
set root=(hd0,2)
linux /boot/vmlinuz-<hit tab to auto-complete> root=/dev/sda2 ro quiet splash
initrd /boot/initrd.img<hit tab to auto-complete>
boot

if you are using grub legacy:

root (hd0,2)
kernel /boot/vmlinuz-<hit tab to auto-complete> root=/dev/sda3 ro quiet splash
initrd /boot/initrd.img<hit tab to auto-complete>
