I recently installed a new m.2 SSD into my PC and all of a sudden I am unable to boot into windows. As my HDD was storing my OS I tried all 6 different SATA ports but to no avail. It only detected the SSD and shows “reboot and select proper boot drive”. Entering bios, I am unable to find my HDD in boot options. Clearing CMOS also does not help and I tried 2 different SATA cables, drive was definitely spinning properly.
