I recently installed Linux Mint on my computer while BitLocker and Secure Boot were enabled, but I've since turned off BitLocker and left Secure Boot on. Although everything is functioning well, I'm not using Mint anymore. The problem is that every time Windows gets updated, I have to go through a hassle of manually booting into Linux Mint three times via the UEFI boot menu. It's even necessary because booting into Windows using GRUB triggers a 'pin is not available' error. I'm looking for a way to safely remove both GRUB and Linux Mint without messing with my BIOS/UEFI settings or affecting my Windows installation. Just to clarify, Windows is on C:, my personal files are on D:, and E: has Linux Mint and GRUB.

To remove Linux, you can use Windows' Disk Management tool to delete the partitions where Linux is installed, then ensure Windows Boot Manager is set as the first boot option in your UEFI. It's a straightforward process if you follow these steps!
First things first, set Windows as the default boot option in your UEFI settings. This should help a lot with the booting issue. Also, it's wise to create a Windows installer USB stick before making any changes. I’m not quite sure about your setup, but if E: is where you have Mint, make sure you know the partition layouts so you don’t accidentally delete something important!
Just a heads up, if you're using an HP Omen, the BIOS/UEFI settings can be pretty restrictive, so you might have to dig around a bit.
