    Why GPT instead of MBR partitions for boot drive?


    My boot drive is a 512 GB SSD and it has MBR partitions. I'm currently running Win 7 Pro 64 on an ASUS motherboard system with a UEFI BIOS.

    I'm about to upgrade to Win 10. Is there any benefit to redoing the boot drive with GPT partitions as part of that process?

    Secure Boot works better with GPT formatting.

    Read the msgs in this thread.....bottom line is GPT IS a better choice.

    Old Mike,

    Thanks. For me the deal clincher was secure boot that protects against rootkits. Now I'm going to try that utility that allows conversion in place from MBR to GPT.

    I am pretty satisfied with MBR on my SSD. I think the "GPT is better" mantra is out of proportion.

    GPT allows more than four primary partitions

    You can use drives over 2.2 TB with OS on it if GPT.

    GPT supports secure boot.

    Easier to repair boot issues with UEFI install.

    So no it is not out of proportion!

    Actually I prefer MBR for the dual boot situation, as where if you wish to access the other os is not possible with GPT.
    I believe the above posts refer to TB not GB.

    MBR limits the maximum addressable storage space of a disk to 2 TerraBytes (232 512 bytes). NOT Giga
