    Your computer has a UEFI BIOS so you can convert from Legacy-MBR to UEFI-GPT.
    As already said, Legacy-MBR performance is the same as UEFI-GPT.
    - With disk manager, delete all partitions on the M.2 drive (for now leave it unallocated)
    - To apply the mbr2gpt, first expand the C: partition to the right.
    - Follow my instructions to do a UEFI-GPT clean install.

    Hello @jm44jg39,

    If you wanted to investigate the Pro's and Con's of MBR and GPT in the future, these might help . . .

    As HDD's/SSD's have become larger now than previously available, it makes sense to use GPT because you can have MORE Partitions and the limitations are far less than using MBR.

    I hope this helps.
