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!

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.

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.
