I have 2 hard drives installed on Dell dimension 8200 running windows xp. Both hard drives show up in both the BIOS and device manger. I can not see the second hard drive in either my computer or by opening windows explorer. I also tried to boot from 2nd hard drive and it said no boot device found, F1 retry or F2 reboot. I think it may be a problem with a jumper setting. Any help would be greatly appreciated.
