    Find free space on an external drive and / or the cloud so that the disk prerequisites are met:

    Hello zbook, I've done all the things you asked for earlier on. I've also exported my images with robocopy to something rare - an external drive with spare capacity.

    I'm assuming that from the results I posted, there is nothing wrong and I can move onto the next step ?

    But having read Shawns tut and the MS site you pointed me to about using mbr2gpt.exe won't work on my disk as I have no spare partitions (see my starter post), you will see this from my screenshots that I'm already using 4 partitions, have I understood this correctly ?

    Thanks, Stuart

    Years ago, I used Linux Mint to convert an MBR disk into GPT without data loss.

    Hello Matthew, spooky your comment. I was looking today at Mint (now v20.1) as a potential dual boot, as a lot more apps I use are plain Lx install not WINE. I used to be a Crunchbang user for years and a bookmark I forgot about was this from Rod Smith using fdisk
    GPT fdisk Tutorial

    I just have to work out whether to do another Kari tut and move my users back to c:\ to get my partitions down to 3, then move the users again or to just reinstall clean and move the users, or use GPT fdisk.

    I'm going to mark this a solved, thank you tenforums for my giving me a better understanding.
    Thank you. Stuart.

    Guess I'm missing it but don't see any mention of an Extended partition which can hold several logical drives.
    Hello Berton, sorry I must of skipped your post on my way down through the thread but you can. I've done it as per the screenshot from the MS table on the thread starter, it works OK but the MS disk management view window is uber poor.
    Thanks for pointing out.
    I'm now up to speed with this stuff (well I think I am ) and I'm going for the gpt disk and UEFI. Cheers, Stuart

    How to convert MBR partition table to GPT without data loss

    I used the above method. Live Linux Mint includes gdisk.

    sudo gdisk /dev/sda

    sda was my hard disk.

    Hi Matthew,
    Thank you for the link. Yes as I've got everything backed up this is what I'll do (I know gparted ). I've not got the laptop until Saturday - zoom calls again, so I am banned from doing anything to it until after these mission critical calls have been made.
    If it fails I'll just do a clean install as that'll be faster. Many thanks, Stuart

    Another option to consider is restoring an image using Macrium (MBR > GPT)

    This is from @topgundcp

    Convert MBR to GPT using Macrium Reflect. See description for the steps. - YouTube
