The system isn't detecting any bootable drives on the SSD.
Attempting to start Windows 10 from an older SATA SSD is challenging; the UEFI BIOS isn't detecting it properly. On my ASUS B560 board, the system identifies SDD devices but doesn’t appear in the boot menu when I press F8—showing "No bootable devices." Enabling CSM in the advanced settings still fails, requiring a hard reset of the CMOS. Windows 10 should be listed under Crucial_CT1230. Since this is new territory, any advice would be very helpful!
You may need to navigate to 'Advanced' settings to enable Legacy boot. It seems the system uses an MBR drive.
In SATA Mode Selection I found two choices: AHCI and Intel RST. Both worked, but neither allowed me to start the system.
I resolved the problem by changing all my MBR SSDs to GPT format, including the C: drive on Windows 10. The process required replacing the motherboard with an older one and using AOMEI Partition Assistant. Eventually, I was able to boot from the drive again. Thanks for your assistance!
