I bought a laptop, a celeron under the V6000 series, without preloaded software. I had a hard time installing Win XP SP2... then when I went on to look into the bios, I changed some options including disabling SATA support. After that, there was not problem in installing the OS. Later, I changed tehh BIOS options to what they were... and when I tried to start... i got a blank blue screen and it was there until i turned the computer off. In short, the OS loads only when SATA is disabled in the BIOS... May I know the reason and am I loosing anything if I disable the SATA access in BIOS? Thanks in advance, Regards, Arun Kumar.
