Question Restore mapped volume to main drive

[kep55]

I found I still had GRUB from an Ubuntu installation on my laptop. Going to https://askubuntu.com/questions/429...oader?newreg=60fc1cdbb7eb44d8956dcacb62478bbe and followed the steps listed. The steps that have now made me nervous are:

-Type list vol to see all partitions (volumes) on the disk (the EFI volume will be formatted in FAT, others will be NTFS)
-Select the EFI volume by typing: sel vol Y where Y is the SYSTEM volume (this is almost always the EFI partition)
-For convenience, assign a drive letter by typing: assign letter=Z: where Z is a free (unused) drive letter
-Type exit to leave disk part

How do I remove the assigned drive letter set in step 3 without losing the EFI volume?

I thought I could go to the command prompt and delete the volume. I didn't do that as I was afraid I'd lose the entire EFI partition and therefore not be able to boot my computer. Or am I worried about nothing? I didn't see an answer in the original post.

First and foremost: do you have all important data backed up at least 2 x to locations away from the laptop in question.

Plus have verified that the backups are recoverable and readable?

Open the Disk Management window.

Expand so all can be seen.

It looks like the volume still exists where it belongs. I've mapped network drives and know I can unmap them easy enough. I was quite leery of unmapping the efi volume.
I had to include the link as I kept getting a message the image could not be loaded.
