First, the relative system specs:
Asus P5KR Motherboard
Intel Core 2 Duo 2,66
Seagate 160GB SATA Drive
Windows XP Pro (SP2)
Maxtor PCI IDE controller (2 extra IDE channels via PCI)
160 IDE drive via USB external box
I installed WinXP Pro on the new SATA drive without problems (plugged into the red SATA1 port on-board), then installed the4 necessary drivers for the IDE card, and everything worked fine. I then went to install a second SATA drive (500GB) and plugged it into the other red SATA port (mistake?). After that, I cannot get the OS to boot, I get the error:
"reboot and select proper boot device or insert boot media in selected boot device and press a key"
I then removed the second SATA drive (500GB), hence reverting everything to what it was originally, and I still get the same message and cannot boot Windows.
I've tried everything including:
-Unplugging the IDE expantion card
-Changing boot device order
-choosing 'F8' from POST screen to choose boot device (chose first SATA where the OS is located)
-Setting BIOS to read SATA as RAID (from original setting of IDE)
-Plugging new HD into the other SATA plugs (3 and 4, which are black, non-bootable)
Nothing has worked, and I cannot load Windows.
What got screwed up when I plugged in that second drive? I've rebooted dozens of times before with just the one drive and everything is OK.
