Does using mbr2gpt in Windows work for Linux?

Hi, I want to make my system full UEFI, So that it's easier to make partitions. If I use Windows's mbr2gpt, will LM boot? Thanks.

Is there a windows install on the same drive?

I have never tried it with a dual boot drive.

Assuming your Mint partitions are not damaged because MS thinks your ext4 partitions are just empty space, you would still have to create the appropriate EFI folders, re-install the efi version of grub from a Live USB environment, and edit /etc/fstab. That is not a trivial exercise.

My suggestion is to back up your mint data somewhere else (different drive), and then go ahead with the mbr2gpt conversion. THen wipe the mint partitions, re-install and restore your backed up data.

What's the problem with an msdos drive? While there may be limitations, unless you have a drive +2TB there is no compelling need to change.

Oops, forgot to add solved here. No worries, it successfully worked, with a cost. Delete all the current Linux installation, then use MBR2GPT. I have plans on installing a 2TB SSD on my laptop. And I want to be updated on the tech world, so I made it GPT. Anyways, Thanks!

Glad it worked.

For the record, mainly for future-proofing and flexibility purposes, I've been setting up all my disks as GPT for some time now and only one of those systems is actually installed & booted in (U)EFI mode. I create an empty EFI partition to be populated when needed. i.e. if that disk is subsequently required to work on a (U)EFI system.

In Mint I believe you also need to create a bios_grub partition to make this work.

ETA:
You need t add [SOLVED] to the beginning of the title in your opening post in the thread.

Only if you want to install linux on a GPT drive in legacy mode. pbear wrote a tutorial on it a while back (and a while since they've been on the forum).
