I have a computer with 4 SATA disks connected, 2 to the motherboard and 2 to a PCI-card.
I've moved all the disks from other computers so 2 of them already has windows installed, the other 2 has just had data on them.
I know one of the windows installations works and i want to use this install. If i only have this disk connected the computer boots fine.
The problem is that when i boot with all 4 disks connected i get an error message about not being able to boot. This message is in swedish(the wrong windows installation is swedish) so it has to come from that installation. Ok, that means it is trying to boot from wrong disk, i try to pull out that disk but then i get the same error in english. I pull out the fourth disk instead I get another error about NTLDR not being able to load.
If i disconnect all drives except the one with the correct windows installation, windows boots fine and i can also connect the other drives while windows is running and browse around in them without any problems.
I have no clue what to do. In my BIOS setup i can only select SATA as boot-option, not the order of the disks. I also tried to remove what's left of windows on the other disk by simply deleting everything in explorer(got hidden- and sytstem-files visible).
Both windows installations are XP btw.
Edit: I switched the cables around and now it magically works. :)
