Your problem must be with the master/slave selection or cables. If you use cable select try using selection jumpers. Use the 2nd IDE channel as well with both as masters - try changing boot sequence in the bios as well. Check cables and pins
My computer won?t boot with two disk drives. System is XP Home. It will boot and run fine with one SATA drive or one IDE drive but not with one SATA and IDE (as master of course) or two IDE?s. The motherboard is an ABIT model #VT7 2.0 serial #_RD430438044020948 . I have gone into the bios and enabled or disabled whatever is needed for the current setup as much as I know to do. Booting from the SATA, with the IDE also installed, it goes a long way, but at the last second it gets an ?Error loading OS? message. I have been disconnecting only the power cable from the drives that I don?t want to use and rebooting. I use a single IDE drive setup for going to bank accounts etc?and reboot with the SATA for use with web surfing and email etc. The setup works well except when booting with any two drives powered up. It has worked in the past with two HD's but stopped recently. Please help if you can as I am at my wits end to make this work.
