Athlon processor and Win 2000

This is the 3rd Athlon based PC that has given me problems. But only with Win 2000. Win 98 and Win XP work fine. After installing Win 2000 and the PC reboots, it starts to load 2000 then suddenly goes to the BSD and says “boot device is inaccessible”. I’ve looked the BIOS setting and didn’t see anything unusual, reformatted the hard drive. Am I missing something? I’ve tried formatting the drive in Fat32 and NTFS.
