Can I blow out my EFI windows partition? [SOLVED]

Post by mccx »

Greetings all,
I have Acer Aspire R5-471T, Entirely Unremarkable machine; dual core I5 @ 2800 MHz, Skylake GT2 [HD Graphics 520] , 7.67 GiB ram. with a LITE-ON model 250 Giga ssd.

On partition #1. EFI /boot/efi , BUT I just deleted the Windows 10 partition to give myself more space. It boots ok. But I still have the EFI boot drive which claims there is a Windows partition.

Q. Can I delete the " EFI /boot/efi " drive and replace it so that I don't have four options when I boot up?

Not if Mint is installed in UEFI mode.
Please run this in your terminal and post results:

and

FWIW, there was a thread on this in the last week or so and, as I recall, they found a solution. Try search and/or simply scanning the topic lists.

Withdrawn: The thread of which I was thinking (here) raises a similar issue but not this one.

Post results for

Code: Select all

sudo ls -R /boot/efi
Likely that the efi file for windows is still lurking and the EFI partition needs to be there or Mint will not boot either

there is a small typo : a space missing, it should be

Code: Select all

sudo rm /boot/efi/EFI/OEM/Boot/bootmgfw.efi
sudo rm /boot/efi/EFI/OEM/Boot/bootmg.efi
This should indeed remove windows entries from grub (after the update-grub). If you still have some entry left, please post the output of

Code: Select all

cat /boot/grub/grub.cfg
so that we see what is left

Thanks, It totally worked. I was able to finally delete the Windows reference at boot up.
