3. installed, restarted A COUPLE OF TIMES IN INSTALLATION.
4. at 60% of installation, when he was completeing inaLLation, the screen went black, and 2 sec later, a vertical line apeared top left corner, and then a blue screen apeared with some writeing, and 3 out of 4 to way bottom, there was a counter 1-100, and it went in a split second. ALL HE COULD MAKE OUT FROM THE MESSAGE WAS,: hardware, vendor, hard, driver, itechnical information (000000x0000) x (00000x00) (something like that) then it restarted, and kept doing same message restarting all night. help. the other time my friend tried to do a clean installation from xp, and it was succss, untill thecmpleting instalation, message, and when it restarted there was a list: old windows, windows vista, and windows setup rollback, i tried windos vist, and message came, so i tried windows rollback, and it sais the installation was not success full, and it set my settings back for me to use win xp, again.
