Question Linux Mint not deleting from Boot Options

[donline]

Hi everyone,

I have a laptop with dual-boot (Windows and Linux Mint). The drive is around 500GB and I allocated 50GB to Linux Mint.

Today I launched Linux Mint from live boot (USB stick) and formatted and deleted the allocated drive space (partition) for Linux Mint so now there is 50GB empty space unallocated - there was an option to expand the size of the Windows partition (and use the free 50GB) in Disks software - is it fine to do that or will it affect the Windows installation (currently just has the initial install where you are asked to set up Windows)?

Also, I went into the BIOS to remove the Linux Mint (shows up as ubuntu) boot option and selected delete boot option from the UEFI/BIOS but it still shows up. Then I tried the following which did not work: efibootmgr -b [ubuntu boot option number] -B

Could you please help with the two issues above. Ideally, I would like to fix the issues without having to log into Windows if possible.

Thank you!

Format bootloader partition.
On legacy/CSM system bootloader partition uses NTFS. On UEFI system bootloader partition uses FAT32 file system.

format h: /fs:ntfs​

or​

format h: /fs:fat32​

and reinstall windows bootloader.

bcdboot c:\windows /s h:​

​

C: - windows OS partition, H: - bootloader partition.
Replace drive letters accordingly to your configuration.

Thanks very much SkyNetRising
I managed to remove Linux Mint (ubuntu) from the boot menu.

I have attached a screenshot from Disks (Linux Mint disk management).
Is it fine to just add the 50GB of free space (was originally allocated to Windows before I installed Linux Mint and later removed it) onto the Windows partition (OS Partition 3 in the screenshot attached)? Would doing so negatively affect the Windows partition (it is currently just a new install of Windows, pre-setup where you turn the computer on and you are asked to set up Windows for the first time)?
Thanks again!

If unused space is right next to the partition (to the right), you're trying to extend, then yes - you can extend.

Thank you very much SkyNetRising.
Glad to say everything went well with resizing the partition as you suggested.
