    Hello ! my asus laptop has been delivered with W8.1 from factory with an array of 3 partitions, I'd like to make a clean install of W10 and resize the partitions, converting to mbr in the process and deleting the non system ones in order to have one single partition (mbr) which I'll divide later in two.
    Pls explain the howtos
    thank you

    Just save you important files to another USB hd and install 10240 from DVD or USB (rufus UEFI mode), W10 advanced install setup will help you to make all the partitions you want

    Why would you want MBR for windows 10?

    UEFI is lots better and faster...

    Without using any third party software, you will lose all the data in your HDD, so make a backup, also you may need to configure your bios to work with mbr.

    Boot using windows USB/dvd, In install now page click Repair/Troubleshoot > Advanced > Command Prompt

    Type

    diskpart

    list disk

    select disk 0 (0 = your GPT disk; change if needed check in List Disk)

    clean

    convert mbr


    Close restart

    Thank you everyone :)
    I want to convert because Asus factory defaults are set to 4 partitions, the system one takes 500 gigs from the drive total of 1 tb, which is stupid from Asus imo, I had no choice when I fired up this laptop for the first time.

    @ Crossup : I think I'll do it your way, just one more question: will this allow me to reallocate partition space from within windows ?

    Yeah Asus is a bummer with partitions that are way too large. I use Acronis Disk Director to resize. :tasty:
