Hello, I have a little problem here... Tommorow, was completely cleaning my pc (hardware) so i had all pluged out etc. But when I have connected everything back, I got screen saying "reboot and select proper boot device", i have tried everything... And suddenly i tried to connect only the 70 GB hdd with OS and it works, so i get the screen only with my 250 GB hdd pluged in... I have tried to swap all the bios boot setting (order of devices) but doesnt work. Please help me, my pc is complete piece of crap without the 250 GB disk... (Everything was working before and I have done that about 5 times)
 
The OS is on 70 GB, the one which it boot with, whatever the OS is installed quite long while. PC was working perfectly before tommorow, when i cleaned it. Just when I connect the second 250 GB the pc wont boot even from CD...
