We just installed new 300 GB Seagate Sata drives in both of our computers. The installation went fine & we used Seagate’s disk wizard to transfer data over, telling it that we want to use the drive as a boot drive & keep the old drive in the system. The program told us we completed the installation. Our drives are recognized by Windows XP & we can see data on them. However, when we try to change the boot sequence to boot from the Sata drive instead of the IDE drive we get the message: Error Loading OS & a black screen. Our motherboards are ASUS A8N-SLI boards & we have enabled SATA in the bios. What are we missing & what do we need to do to be able to boot from these drives? I do not see any additional SATA drivers on the ASUS web site & Seagate’s site says their drives do not need any additional drivers. Can anybody help?
