The system apparently can't access the hard drive. That's why it is saying 'no bootable device'. Your hard drive appears to have become corrupted/unusable. Boot to your Windows installation disk and have it try a repair.
If you have no Win installation disk, the install pgm may be on a recovery partition on the Hard drive. Watch the screen at boot up for a key to press to access the recovery/restore partition. sometimes the ESC key.
