    Win 10 won't boot, if I disconnect secondary drive(s)


    Evening chaps

    Bit of a problem.

    I have Windows 10 installed on my SSD primary drive. I also have a 4 TB RAID 10 array that I want to remove to reutilise the disks in my new NAS. However...

    If I remove the drives, windows won't boot. I've seen various errors, but basically it loads to logo, spins round and round and then halts, usually with "inaccessible boot device". What's the problem here? Any pointers appreciated.

    That's because your boot manager is in one of the disk you disconnected. Reconnect to boot and use:
    EasyBCD 2.2 - Neowin
    To move the Boot Manager to the SSD. Follow the screen shot:

    Cheers, but it says that it's already the boot drive!

    Where does it say that ? Can you post a screen shot of Disk Management ?

    1. Download: Macrium Rescue ISO 6.1.1000 and use: Rufus - Create bootable USB to create a USB Boot.
    2. Disconnect Disk 1 from your PC
    3. Boot up your PC using the USB in step 1
    4. Follow the screen shot to fix Windows Boot

    Everytime I try and add the iso using rufus, it starts formatting then Windows 10 pops up with a "Fix USB" box and the rufus install/format fails. Why's that?

    Do you have another USB stick ? If it fails formatting the USB stick, chance it's a bad stick.
