Ive tried googling and searching this forum but to no avail.

I was recommended BT2, ran it from the live disc no problem. The tools aside I was very impressed with the look and feel of the interface. So I would like to use it as an OS.

I was tripple booting Ubuntu, XP and Vista.

I installed BT2, but then couldnt access any other OS, so I had to re-install Ubuntu.

Now when I boot up I have what used to be my Ubuntu grub screen, where I can choose Ubuntu, Windows(which then takes me XP or Vista screen) and bt(on /dev/sda8)

I can still load/use Ubuntu,XP and Vista. When I select the bt option it loads fine for a while then this happens:

RAMDISK: Couldn't find valid RAM disk image starting at 0

VFS: Cannot open root device "current" or unknown block(0,0)
Please append a correct "root=" boot option

Kernel panic - not syncing
VFS: Unable to mount root fs an unknown block (10,0)
<6>Time: acpi_pm clocksource has been installed.

The boot freeze's there and I have to restart the computer.

I have only been using Ubuntu for a week and really dont like it so want BT to be my main OS if its possible, but still having a grub menu to choose XP and vista when I want it.

Sorry if this is beyond the real of the newbie forum. Please dont flame me for being a newbie. Any help will be appriciated, be it advice or links to check out.
