I recently transferred my OS from m.2 SATA SSD to m.2 NVME SSD using EASUS todo backup clone function.
Everything worked fine but if it gets restarted it will stuck at boot up showing "Checking media presence , no media present" indicating missing boot device. However, turning it off and on using the power button it will boot normally again.
Now I tried a full reinstall Windows this weird behaviour still persist. Is there possibly a BIOS issue of my machine when using a NVME SSD? It is a custom build Clover Laptop.
