Problems in booting up (video incl.)

I'm running Mac OS X on one hard drive, and Vista on a second. When I boot up on the Vista hard drive, I get this long string of text, about partitions or something. I need to know if it's possible to get rid of that message, or if something's wrong with my system, or anything would help. I recorded a video of it, which I've uploaded here:

MEGAUPLOAD - The leading online storage and file delivery service

I've uploaded it onto Youtube since some people have told me Megaupload is a virus site... whatever, here it is anyway.
