How do i remove efi system partition, unallocated space

Griff2bad · 23 Jul 2019

Hi, ive run into a bit of a problem. how do i remove the efi 100mb healthy file system?

Also, i know how to convert a dynamic disk to a basic disk, but the option is greyed out.

also, it wont let me extend the partition.

i was mucking around with dual booting windows 7. i almost ran into a problem where i couldnt boot windows 10, as i now have two windows boot managers in my uefi.

thanks

Before you delete it you need to be sure your not actually booting from it pull the cable from the drive and make sure windows boots with it gone as it often puts it on other drives

actually, i think i know whats happened. when i dual booted 10/7, i put 7 on disk 4 (G Drive). now the efi bootrec for windows (c drive disk 0) is there too. is there anyways too move it?

officially you are in a stalemate situation , however i would suggest you use minipartition wizard to empty some space on main drive then clone copy the efi partition to it then reboot with disk 4 unplugged and see if it works .

i just formatted c drive and deleted the efi partition on g drive. it deleted all my files on g drive, and when i reinstalled windows 10, efi is STILL on g drive. and mini partition wizard says i cant move it?

You should have disconnected the G: drive when you reinstalled W10. You can then reconnect it once W10 is properly installed.

As its the boot drive it will be locked

OK, did as suggested. removed the power from all other hdds and installed windows 10 fresh to the ssd (c drive).

As shown figure one. Attachment 241119

However, theres still and efi and unallocated space problem on disk 4 (g drive). Figure 2.

I know for certain its not booting from it.

How do i get rid of it?

Then you should be able to delete the partition.
