    Can I delete one EFI partition?


    Hi at all! I have used this procedure to move from Legacy BIOS to UEFI. Now msinfo32 shows UEFI, but I have two EFI partitions. See here:

    Can I delete the third partition, without making my system unbootable?

    Thanks in advance!

    :)

  2. Can I delete Recovery, EFI and OEM Partitions?

    Hi,

    Thank you for posting on Microsoft Communities.

    Recovery partition consists of some important boot files and other tools. Recovery partition is created by the System Manufacturer, in case you may want to revert back to the factory settings and for troubleshooting purposes.
    It is not recommended to delete the recovery partition. If you wish to delete this partition, then you will have to get in touch with the system manufacturer.

    I suggest you not to remove the recovery partitions. If the partitions are deleted you will not be able to use the recovery options.

    Hope this information is helpful.

    Thank you.

    You need to resize that partition which is saying you low space.For that Download Ease us partition manager

    and reshuffle the size to ~800 MB or more.

    Can I delete one EFI partition?

    Hi, I would have expected to see
    a. a Recovery partition - 450Mb. Without that, you have no Advanced Recovery options or automatic repair on restart should things go wrong.
    b. a 16Mb System partition.

    You should be able to delete that middle EFI system partition. This is what I would do. Make a bootable USB flash drive or DVD of Kyhi's recover tools:
    Windows 10 Recovery Tools - Bootable Rescue Disk

    Boot the computer from it (to make sure it works, for one reason). Use Macrium Reflect Free to make an image backup of both the EFI System partitions. You can use AEOMI partition assistant on the same flash drive/DVD to delete the middle EFI system partition, then reboot the computer from the HDD/SSD. If it has a problem, boot back to Kyhi's recovery tools and restore the EFI system partition you deleted from the backup image and then attempt to delete the other EFI system partition from the HDD/SSD.

    Thanks for the reply!

    I was wondering a thing: can I boot Ubuntu from USB, then delete that middle partition using the manual partition manager in the installer, and finally extend the main partition of my HDD on Windows?

    Not sure. I know you would be able to with the partitioning program on Kyhi's recovery drive.

    Can I delete one EFI partition?

    From Windows, just use diskpart to delete the partition. Open admin comnmand prompt and type:
    diskpart
    select disk 0
    select partition 3
    delete partition override
    exit

    NOTE: I am assuming you want to delete the partition next to C drive which is partition 3.

    Thanks, topgundcp!!! I knew that command would have worked, but I was afraid of losing my data.
    Now I have also expanded my C:\ drive, filling the remaining 100 MB.
