Will no one rid me of this turbulent EFI Partition?

Healthy (EFI System Partition) … what the?
The EFI System partition (ESP) is a partition on a data storage device that is used by machines that adhere to the Unified Extensible Firmware Interface (UEFI). Generally this is a recovery partition, or a partition added by vendor disk management software.

In the Windows 7 Disk Management tool we cannot modify the EFI partition, the disk management menu is disabled. Clicking on the only available option “Help”, is not very helpful.


How do we delete the EFI Partition?
We cannot delete the EFI partition via the Disk Management tool, we need to drop down to the Windows 7 command line and jump into DISKPART.exe


DISKPART> list disk


DISKPART> select disk 2

DISKPART> list disk
(Note that Disk 2 is now marked with an asterisks *)


(Beware, Dragons! Note that clean will erase the selected drive – be sure that you do not have data you require on this drive and that you have selected the correct drive)

DiskPart succeeded in cleaning the disk.


Back into Disk Management
Format the drive in the usual manner as you now have the options unlocked.
With our move to Win7 and OS.X.7+ exFAT has become a good choice for the larger drives YMMV.
