BT4 DVD booting into grub mode (eg 'grub>')
I recently acquired a BT4 live DVD. I have checked the md5sums for the files on the disk and they are all correct. It boots correctly on a separate laptop and a desktop and I have previously booted two seperate linux distributions on my laptop (a PacardBell EasyNote) however, when I boot from the BT4 DVD I am shown a message starting along the lines of 'Minimal BASH like editing supported....' and then a prompt reading 'grub>'. There have been a few previously reported cases of this which I have found in the archives but none of them seem to have any ways to fix the problem.
I have been trying to manually boot using the menu.lst file on the dvd as a guide, first selecting a root partition then trying to boot the kernel image, with or without the parameters suggested. My original plan was that after loading the kernel I would then use a command along the lines of 'initrd /boot/inidrd.gz' and then boot, however, I have not been able to successfully load the kernel image. Whenever I try to use a command starting with kernel the laptop freezes or enters some kind of infinite loop which I can only stop by manually rebooting the system. I have also tried to access the cd drive via an Ubuntu 9.10 partion using /media/cdrom(0) and /cdrom but these had no further visible success.
Any help or suggestions as to commands I should be trying are welcome.
Menu.lst file on the DVD is listed below.
Thank you for your time.
