    How do I move the UEFI boot manager from one drive to another without migrating the OS?


    I had Windows 10 Pro installed on a 256 GB NVMe SSD. I decided to try out Windows 11 Pro and installed it onto a new 500 GB NVMe SSD in a dual-boot configuration. I've since decided that I like Win 11 better and deleted the Windows 10 Pro volume. I've tried to replace the 256 GB SSD with a faster 2 TB PCIe Gen4 SSD, only to discover that the boot manager is on it and the system won't boot without it installed. How do I move the boot manager to the drive with Win 11 installed?

    :)

    Windows Boot Manager

    I recently installed a Samsung 970 EVO Plus NVMe drive to replace my current 860 EVO boot drive. I used the Samsung Data Migration tool to clone the boot drive and then restarted the PC. After numerous failed attempts to reboot, I noticed that there were
    now two Windows Boot Managers in the UEFI boot priority list. Tried rearranging them, but it still would not boot. Ultimately, I removed the 970 EVO Plus and eventually got it to boot into Windows with the 860 EVO SSD. However, I still have the two Windows
    Boot Managers in the UEFI boot priority list.

    What might have caused this and how do I remove one of the Boot Managers?

    Migrating Win10 to NVMe SSD

    I am going to try what you suggested. I just tried using Linux Mint boot cd to hopefully erase the SSD. Unfortunately there seems to be some sort of encryption on the SATA SSD that prevents Linux from managing the SSD. Funny thing is I never used bitlocker on the SATA SSD.

    USB Drive showing "Not Migrated" in Device manager

    Forgot this one on the list, my bad

    Yes, I have tried the steps above and it did not resolve the issue.

    My pen drive is still showing "not migrated"

    Any further help would be appreciated, thanks!
