Windows 10: USB made with MCT does not boot! Solved

    USB made with MCT does not boot!


    Admittedly, since it's been around 2 years since I tried to boot a PC using the USB media made from the MCT, but unless my memory is faulty, I recall being able to boot from it.

    I tried to boot my crashed HP laptop using a new USB and it would not boot.

    I tried three other bootable USB sticks and they all worked OK.

    So, is the Win10 USB media suddenly not bootable, or has it been this way all along?

    My "plan B" is to make a new USB stick using the ISO I downloaded using the MCT and RUFUS.

    Rufus lets you to choose, what settings to use, like MBR (notebook) or UEFI (usually most desktops).

    The issue is most likely with the drive itself not software. Some drives just will not boot no matter why you try - I have no idea why. I guess it is USB driver related.

    Don't use Rufus or anything - do this

    1) download iso from MS

    2) put usb drive in PC and prepare it like this

    Run an admin command prompt and type following commands

    diskpart

    list disk

    select disk n (n=number of USB drive, usually last on list)

    clean (wipes drive - be certain right drive has been selected)

    create partition primary

    select partition 1

    format fs=fat32 quick

    active

    assign

    exit

    exit


    3) Note assigned USB drive letter

    4) mount iso as a drive, and copy all files to USB drive

    5) boot from USB drive

    If it does not boot now it is a problem with the drive.

    Respectfully, MBR V. UEFI has nothing to do whatsoever with whether the computer is a notebook or desktop.

    The best way to create the USB flash drive from the ISO file is as @cereberus posted. Making the USB flash drive that way makes it bootable in both legacy BIOS (MBR) computers and UEFI (GPT) computers.

    Update: Tried the USB made using RUGUS -- same problem.

    Made a DVD using the same ISO -- it boots fine.

    @cerebrus: Will try what you suggested and report back the results. Thanks

    UPDATE: IT works -- the laptop booted from the USB stick!

    I am smugly polishing my halo right now :-D.

    Seriously, glad it worked.

    I never bother with rufus now.

    Some usb drives have problems booting, my Sandisk Cruzer was one such drive.

    I was never able to boot any notebook with UEFI created ISO, even when notebook supported UEFI.
