[SOLVED] Asus H510M-A cant detect bootable devices

[GCris]

Hello! Recently i upgraded to a new motherboard + CPU + RAM. It automatically puts me in the BIOS. When i change CSM settings then it restarts, but no output from motherboard comes up to monitor when restarted. I changed the CMOS battery. However for some reason when i press the Boot Menu, it gives me an message saying “The system cannot find any bootable device” The motherboard BIOS sais that everthing is connected and working, but still gives me this message. Advice would be appreciate!

Motherboard: H510M-A
CPU: i5-11600K
RAM: 16GD 2133 mhz
GPU: RX 580

I already have windows 10 on my SSD. And I have files on there that I need, so that they dont delete while installing OS.

Did your old PC had more drives then this SSD? If yes then probably some partitions needed to boot ended up on other drives. Backup the files you need from SSD and do fresh install. Any other way is more trouble then its worth,
