Can not boot on laptop.

Today I downloaded Backtrack v2 and it does not boot on my laptop. First version works fine.
Tried v2 on my PC and it works fine.

When I try to boot on my Sony VGN-S360 laptop, I get underscore sign on my screen for a while. Sounds like my laptop is trying to read off CD-ROM then after 30 or so seconds it proceeds to boot Windows.

I tried Ubuntu Live CD on my laptop and it works fine.

Anyone got any idea what could be the problem?

Yep, it worked. But I also recorded it to a different type of CD-R.

First time I tried it I used TDK CD-R and Phillips CD-RW, both failed to boot.

Then I tried CD-R's that I usually always use (Ubuntu and first Backtrack was on that type of media) and it worked.

I think it was the CD-R, not the speed.

thanks
