    System, EFI System Partition


    Two questions please -1] I had installed UBUNTU on my desktop PC, operating with Windows 10 PRO version 21H1; OS Build 19043.1202, and later removed the UBUNTU software. UBUNTU was installed on a separate SSD i.e., not on the SSD where the Windows OS is installed.The UBUNTU installation, although removed and the SSD formatted, has left behind a folder named "Ubuntu" in the System, EFI System Partition of the SSD where Windows 10 is installed. I want to know the procedure step-by-step if possible to remove the "Ubuntu" folder from the System partition, without in any way affecting the Windo

    EFI System Partition

    So, an EFI system partition is perfectly normal on a Windows 10 disk (I assumed you've done an internet search and discovered that this partition is for booting your system).

    Are you trying to backup the contents of this partition?.... if so, what software are you using?

    UNMOUNTABLE_BOOT_VOLUME after creating new EFI System Partition

    I would probably have booted to a Windows install or recovery media to create the

    EFI system partition by using Diskpart and the create par efi command with any modifiers necessary to make it fit in the correct location.

    I know Linux can use a Microsoft EFI partition but I do know if Windows can use a Linux version.

    Yes, the bcd listing which shows the boot manager and OS loader.

    It may have been easier to use a third party partition manager to change the size of the EFI partition.

    If you might need it, here are the details of an EFI partition from Diskpart.

    Partition 2

    Type : c12a7328-f81f-11d2-ba4b-00a0c93ec93b
