I'm in a bit of a predicament with my T5600. I previously had windows 10 installed on an ssd and after taking it out then putting it back in (for maintenance) I am unable to boot to it. I am almost positive this is a driver issue. I loaded drivers, as well as a fresh windows boot on a usb and it appears when prompted to choose a drive to install to. Yet when I download the drivers and restart without the USB, I still get the error "No Boot Device Found". My bios currently has ACHI and RAID/SATA enabled. I could install a fresh version, but really would rather not go through the trouble of installing all of my software again. Any ideas?
