Ok I bought a SSD and I transfered windows onto it and now i have a start up error "select correct boot device" and if i go into my bios and just hit "discard changes" it will boot windows and i just recently unplug the HDD to see if my ssd will boot by itself and it wont. Do i format my HDD that had my previous windows on it that was wiped when i got my ssd? or if you have any other ideas shoot'em my why please!
