My windows 10 is on the Samsung m.2 Nvme ssd, I have some really imporatant files there. Now, I replaced my HDD drive (which didn't contains windows) with another, which already contains windows installed. The ssd was still connected to the computer with windows on it. I turned on the computer (with both ssd and hhd) and the windows of the HDD booted. I removed the HDD and tried to boot the Samsung m.2 Nvme, it's not working, it's not booting. It says that there is no operating system on it. The BIOS do recognize this Samsung m.2 Nvme. What can I do? Maybe it's important to say that I accidentaly activated Intel Rapid Storage Technology when I was in the bios, I disactivated it later. Is it matters?
