Hi there ! I just got my mother's computer back from a repair shop (they've changed the graphic card, the motherboard and the processor, the hard drive stayed the same) It is a SONY VAIO VPCEE25fx. I used my Windows 7 Ultimate OEM CD I had when I bought her the computer. But then, at the Custom Install step, it says No drivers or hard drive found. I've tried to reload, scan...none. I'm sure the hard drive is ok. Is there a way to fix this ? Thank you so much for your help.
