Well, i just bought some new computer components for my new gaming pc. And that includes a Samsung 970 M.2 EVO 500GB NVME SSD. When all the components were at home and installed correctly and finished i started to download windows to the M.2 disk. And the installation process worked like a charm. And the things that i did when everything was finished with the installation was that i downloaded Geforce drivers and bios drivers and stuff like that. The basic stuff that you usually download after a fresh new gaming computer. But after i got an important windows update and after i restarted my computer because of the update, my BIOS just wasn't able to locate the M.2 disk with windows in it. I've tried everything that i have in my power. I can't specifecely say what kinds of solutions i have tried but i just need help right now. I don't understand how the M.2 disk suddently disappeared after just doing a update and then restart. I got a ASUS ROG STRIX Z390 F-GAMING.
