I removed IDE HDD with Win98, replaced it with SATA HDD having WinXP. I get DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER when I first boot, but then I next do a Ctrl-Alt-Del and it boots up fine. New CMOS battery installed, did the Setup Utility Reset action, all to no avail. On Restart I don't get the message, but on a cold start I do. Any ideas?
