    Move efi and recovery partitions from a raid array I want to split

    Having gone from windows 7, to 8 to 8.1 to 10 without a reinstall I've started to have a few issues so I've just reinstalled windows to a new drive.

    Trouble is, I didn't think too much and left the old RAID array connected so the recovery and EFI partitions are still on it and Windows Setup used these instead of creating new ones.

    I want to unRAID them now to get my 2 SSD's back but how do I copy the recovery and efi partitions over?

    Raid 0 I believe ??
    Spiting the SSDs will result in data loss.. backup data. Change Raid back to AHCI in bios.
    Now you can install OS on any drive you want.

    Ideally I wanted to do it without re-installing.

    Turns out it was actually very easy after all that, I didn't even need to use the installation media.

    I just shrunk the new Windows partition down by 100Mb and created a new efi partition using diskpart, then just ran bcdboot C:\Windows /s

    I rebooted and changed boot order and all good

    I've now split my RAID array and got my drives back, hooray!
