My PC consist of Intel 915 chipset motherboard, with 3 Ghz processor and Western Digital SATA hard drive, for windows installation it is fine and speed is very fast but while installing linux either mandrake 9/redhat 9.0 it doesn’t go well and give the message that an error occured. No hard drive found. So for this linux installation what will be my bios setting and one thing more in the begining pc unable to recognise the hard drive but any how this problem is shorted out but linx installation is still a problem for me please suggest.
