Hi , i downloaded a file and it contained a trojan , when i restarted my pc i couldnt get into my HardDrive C: , but i have 2 harddrives , on C: i have windows XP , and on F: i have Windows 7 , so from the BIOS menu i booted with F: and installed a anti-virus program and deleted the file i had downloaded , now from my F: i can get in to my harddrive C: and look at pictures movies etc , but when i open the BIOS menu i cant find it anymore , i cant boot from my C; again , only from my F: , and thats my problem . Thanks for respond anybody :P

The Virus may have taken out your MBR. Do a repair install of Windows XP to your C:. Make sure you pick the right partition when you do it. Don't want to mess up your Windows 7 install.
