Ensure the bootloader is set to use the main drive instead of the newly installed one.
I currently possess an NVME storage with Windows 11 running as the primary unit. Earlier I added another SATA SSD and set up Windows 10 there. The issue arose when the Windows 11 bootloader became damaged, and after removing the SATA SSD I could not boot into the main drive. I resolved it using Method 2 described in the provided link. Now I wish to repeat the process but keep the bootloader on the main drive instead of automatically switching. Since the last time it worked smoothly after moving Windows 10 to the secondary drive, I’m uncertain how to manually prevent the bootloader from launching from the backup drive.
You can detach the SATA SSD, then set up Windows on your NVMe storage. This implies each drive has a bootloader, and you'd configure one as the primary boot device in BIOS/UEFI. By default, it would start there unless changed. To switch to the other drive, press F11 during POST to select it.
Thank you, I reinstalled the SATA once more and it replaced the NVME. Next time I’ll fix it and follow your advice—disconnect the NVME and proceed.
