My less than 1 year old PC all of a sudden for no reason at all my windows vista says on the boot screen, DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER! I have checked out all the BIOS functions and it seems that the PC does not register the HDD when everything else seems to be working fine. I have tried switching the connections with new ones, resetting it, even the old freezing trick. All do not work. I also cannot load from the boot disc as it goes from the boot screen to a blank screen with the same message every time. I have tried to set the BIOS to read 1st from DVDROM but the BIOS only gives me the option to select CDROM (but I do not have a CDROM installed only DVDROM?) so I can not even attempt a reformat or repair. My cousin says the files might be corrupt but would this cause the HDD to be unfindable from BIOS. Other than buying a new HDD has anyone else had this problem and did they find a solution?
