I have a Vaio laptop PCG-FX215 that I’m working on. The owner reformatted the hard drive with fdisk. Afterwards, it would not load the restore CD. It gives the error of “No fixed disk present.” At first, I thought it was the hard drive, I replaced it with a new one. It gave me the same error. The BIOS shows that it’s able to read the drives. I have put the drives into other systems and they load fine. I put them back into the laptop and nothing. The Recovery CD has some image files to load on the drive, and I think they have to be put on there in DOS mode in order for the laptop to be able to read from the drive. I haven’t been able to figure out the way to put in the DOS string get that to happen. I hope someone here can help me.
