Ive been using Win 7 ultimate 64 bit for a month without problem. After i used the 7loader 1.5v2 By Orbit30 & Hazar the Dell laptop wont boot. First it gives me a message that I have to update the Bios and then it gets to blue screen (Bsod) I tried to boot up from Win vista and win 7 cds but it still gets the error. I read something about that the 7loader have caused this problem by changing a master boot sector or something. Can anybody help me out, is there a boot utilities or something I can use? I really need help here.
Try getting Paragon Partition Manager 10 and tell that to make a boot disk. Then reboot with that disk and see what happens. If you can get in then format your hard drive and then reinstall windows 7. If that still does not help then try updating your bios like the message says and you should be good dude.
