Press F3 To Quit Setup
No mather what i select i get same problem, that hard disc cant be load(found) , and it start with restarting laptop… anyone was in similiar situation that can share experiance with me , since this is something that happaned to me first time….
Answer #1
the problem is that winx is older that vista so it wont format the computer, try using win 7 it really good
Answer #2
try useing windows 7, all my freinds have it and sat that it is like 100x better then XP, and way better then vista.
Uses less ram then vista, and is much better
