I have a 2nd drive which has an EFI System Partition of 750MB and an unused partition of 118GB. I want to remove the EFI System Partition and reformat the entire drive. But when I click around there is no option to remove the EFI. Is there a way?

Thanks,

Eddy

Assuming you are on Windows and are asking about DiskMgmt.msc:

  1. Run DISKPART, which is a command-line tool which uses the same Windows volume manager.
  2. Use list disk and select disk <number> to choose the disk.
  3. Use detail disk and list part just to make sure it's the correct disk.
  4. If you want to delete all partitions at once, use clean.
  5. If you want to delete just the specific EFI partition:
    • First choose it with list part and sel part <number>.
    • Double-check using detail part.
    • Delete it with del part override.

Any third-party partition editor will be able to remove the EFI system partition as well.

Note: Make sure the system isn't actually using this EFI system partition to boot your OS. Have a Windows install USB handy just in case.
