Cant find Boot disk under upstart


i have the problem that when i am starting up my copmuter it cant find my HDD with my System on. under upstart it says cant find boot drive please restart the computer.
Then i start up, push F12 and Select HDD, select my Main HDD and then it starts to windows.

It all started after moving my Main HDD Sata Cable to another plug on the motherboard.

is there anyway to change what disc it boots from first, other than changing the cables ?

Enter BIOS setup by tapping the key given on first boot screen, look for BIOS Boot Order priorities, study how to move HD up to first position, Save and Exit.

If problems persist post back a screenshot of your maximized Disk Mgmt drive map and listings, using Snipping Tool in Start Menu. Attach using paper clip in Reply box.
