I have an existing win xp system and installed new backtrack2 on the hard drive. It did not gave me a dual boot but boots on bactrack only and is hanging giving "kernel panic - not syncing:vps:unable to mount root fs on unknown-block(8,5)" message. I booted with road started to see if my xp is still there, and it is still there. I tried to recover install xp but still it is booting on with backtrack. I guess I made a gogoo on the installation of the backtrack but I would like to bring it again with my first xp system then work out with backtrack later. Can you please tell me how to get rid of the backtrack boot and recover my xp? I did not want to fresh install the xp as I have datas and programs I badly need to use asap. Thanks in advance.
