Transfer SSD to another device, but it won't start.
I retrieved my mom's NVMe drive from her PC and powered it down to repair it. Both units are AM5 gigabyte systems, and everything functioned properly after fixing a few noticeable problems. The main issue now is that the system won't boot on her machine—it just displays a black screen with no loading icon. Is this related to the CSM? It seems like the Gigabyte B650 gaming plus with Wi-Fi is working fine. I managed to get it into automatic repair mode, and after restarting into safe mode, I reached the desktop. It looks like I need to be more patient; it should boot normally but takes a long time. If it finally loads, I’ll leave it running and handle the slow startup later with your help.
The initial startup may appear sluggish, particularly when changing between motherboards, even if both support AM5. Windows needs to reset drivers and storage configurations, which can be resolved by entering Safe Mode—this often completes the process. A possible cause was CSM activation in your motherboard’s BIOS, but since it eventually started (though slowly), the delay was likely due to Windows reorganizing itself. If the system now works, adjust BIOS settings: disable CSM (only in UEFI), set boot mode to UEFI, and ensure Secure Boot is off or set to standard. Verify the boot device is labeled as “Windows Boot Manager.” Keep observing for any irregularities; lingering driver issues or BCD confusion might require cleanup.
