First, boot a Windows 10 or Windows Server 2019 rescue CD and enter the command prompt.
Step 1a: If you have the 128MB + 100MB partitions and they are broken for some reason
list disk select disk list part # visually check you are about # to do the right thing select part 1 delete part override select part 2 delete part override
Now continue with step 2.
Step 1b: If you don't have at least 228MB of unpartitioned space in front of your Windows partition
Boot the gparted Live CD and move your Windows partition to the right, 250MB is usually fine, then continue with step 2.
Step 2: Recreating the UEFI boot partitions and installing the bootloader:
create partition efi size=128 format quick fs=fat32 label="System" assign letter="k" create partition msr size=100 exit bcdboot C:\windows /s k: /f UEFI
Step 3: Profit
That's all there is to it! Make sure to set your computer to UEFI ONLY, because it's past 2020.
