I have an old laptop running Windows 10, I bought a new hard drive where I want to install Lubuntu. I thought it was going to be super straight forward but when I started to do some research online I found different posts/articles about problems with GRUB2 and/or the BIOS/UEFI mode, so I would like to ask if the following procedure makes sense.
I know there's a lot of material out there, but it is complicated to know what to do, because some people make extremely complicated instructions while others make it really simple.
Some sources I already checked include:

The procedure I propose here is the conclusion I arrived at after the research.
Current system:
- Hard drive with Windows 10 (disk 1)
- boots with BIOS in Legacy mode
Proposed procedure:
- Change BIOS Legacy to UEFI
1.1 Use Windows MBR2GPT tool
1.2 Change BOOT mode from the Bios settings to UEFI
Remove Disk 1
Plug Disk 2 and install Lubuntu from bootable flashdrive (any special requirements when creating the drive with Rufus?)
Turn off laptop and Plug Disk 2 again
After that I could, as far as I know, choose from which disk to boot when I turn it on.
Am I missing something? Is there any special consideration I should not overlook? Will I have any trouble with GRUB2 or the Windows Boot Loader?
Thank you a lot in advance!
