    Moving / recreating EFI partition


    I recently upgraded my laptop with an SSD, moving my older HDD into the optical drive bay. I then installed Windows 10 from a UEFI USB (using the Windows 10 media creation tool), on my SSD (with the HDD also installed). But the problem is the EFI partition is still on my HDD, not the SSD. I would like to move the EFI partition to the SSD, as the HDD I feel might be on the verge of failing.

    Is there a way to either recreate the partition, or move it from my HDD to the SSD?

    I came across this thread (System won't boot after removing second hard drive, EFI? - Page 3 - Windows 7 Help Forums), but it mentions you should remove the HDD first before following the steps. But, because the screws are starting to wear out on my laptop (horrible T5 torx screws), I don't want to be opening it up too many times to insert and remove parts...

    Any help greatly appreciated!

    Moving / recreating EFI partition


    Hi,

    this post seems to be exactly what i need to fix my problem.
    after installing a SSd and migrating windows 10 on it, i tried to remove my old HD and windows would't boot. i realized that the EFI partition was still showing on the old HD but not on my new SSD.
    i followed your instructions to create a new EFI partition on the SSD but when i type the bcdboot X:\windows /s S: i get a "failure when attemting to copy boot files" message. (i replace the X with C which is the volume of the SSD where windows is)
    can you help me?

    Moving / recreating EFI partition


    Thanks for your help! So after doing this, can I now delete the EFI partition from the other HDD? Is there a concern to worry about setting the SSD partition as active?
