i recently had something go wrong with my sony vaio vgn-tx series. The passwords on all of the accounts somehow got changed and i cant figure them out. I burned an ophcrack livecd disk for vista(which i have) and put it in. I found out that i need to change the order of my boot. When i try to go to bios by pressing f2 or f8 there is no option to change the order what should i do.
