    How to convert an MBR disk into a GPT disk


    why does windows 10 32 bit(x86) clean install as mbr when i pre-format the hard drive as gpt?

    is there a solution or is that the default and only option for installation? i've contacted asus

    who makes my motherboard to check for uefi details and everything i can think of to ask them!

    their reply is that the memory is the cause---i have 8 gb and not 4gb! their other reply is that microsoft

    has a patch or solution for the problem which i did not see or find on microsoft's site! i've tried everything

    that i can think of including changing all settings in the asus bios and trying every way to change the

    hard drive to gpt and hoping it stays gpt after windows 10 32 bit(x86) is installed! but, every time i install it

    the windows 10 changes it during the install! are there any links or answers that will truly solve this mystery?

    thanx ahead of time to any persons that answer this question!!!!!!!!!!!!!!!!!!

  2. convert MBR to GPT disk

    convert mbr to gpt

    There is a way to convert mbr to gpt without data loss. clean command deletes all datas inside the disk, so dont use this command

    boot with windows dvd , and get into command prompt

    type diskpart , find the disk number , which is need to convert mbr to gpt

    say disk number is 0

    exit diskpart

    type below command in command prompt

    mbr2gpt /convert /disk:0

    wait for some minutes to complete , once you get commpleted successfuly means, exit and close ,

    shutdown the pc , remove windows dvd

    important

    After the disk has been converted to GPT partition style, the firmware must be reconfigured to boot in UEFI mode.


    Make sure that your device supports UEFI before attempting to convert the disk.

  4. How to convert an MBR disk into a GPT disk

    Converting a MBR disk to a GPT disk

    This BS Microsoft stop forcing us to convert from MBR to GPT

    -> The MBR scheme will work for disks up to 2 TBytes.

    I don't care whether it might boot up quicker

    -> MS does not claim that GPT boots up faster than MBR.
