    1) download a windows 10 iso using Microsof tool:

    select the proper windows 10 version (the same installed on your laptop) and choose to save it as iso file when prompted
    2) download Rufus:

    plug your USB flash drive, run Rufus then:
    select ISO image from the dropdown menu near "Create a bootable disk"
    click on the little icon on the right and browse to the windows 10 downloaded iso file
    as Partitions scheme select "GPT partition scheme for UEFI"
    as File system select "FAT32"
    click on Start
    wait until it finish, then uplug your USB flash drive
    3) with the USB flash drive plugged to your PC, boot to BIOS pressin Del key
    4) look if F12 boot menu is enabled, if not, enabled it

    I just registered to say thank you a million times! I just bought the Acer Nitro 5 with Linux system installed and I was pulling my hair out because as soon as I turned on the laptop I was greeted by a shell> command menu...had absolutely no idea what I had to do, didn't even boot into the Linux system. I've had a USB with Windows 10 installed but I was not able to get the laptop to recognize the USB in the BIOS. With this method, I successfully formatted my USB to GPT - UEFI (NO CSM) and rebooted my useless Nitro 5 laptop into the BIOS. The USB was instantly recognized. After that I restarted and booted with F12. I chose the USB and successfully installed Windows 10!

    Thaaaaaaaaank you a million times, I thought I just wasted 1400 euros for a laptop that wasn't even working.

    I have an Acer Nitro 7 and want to dual boot windows 8.1 and windows 10. I haven't found any way to boot from a usb because the motherboard doesn't support it.

    Sure it does. You first have to set and save a BIOS password. Then re-enter the BIOS with the password and disable secure boot. You should also set the USB HDD first in the boot order. Then save settings and exit. Then shut the machine off. Then place the USB stick with the Win8.1 installation iso on it, and install Win8.1 alongside Win10. You might also have to run 'diskmgmt.msc' to reduce the size of the Win10 partition so that the Win8.1 has some free-space (unallocated space) on the disk to install. Jack E/NJ

    Had the same issue. The option to boot from USB was not appearing in the Boot Menu. Turns out the reason was that I didn't format my USB drive in FAT32 format. But the issue was that the FAT32 option was not appearing for me. The reason is because my USB was 64 GB and FAT32 option is only available for disks smaller than 32 GB. So I bought a new USB of size 16 GB and then created a bootable disk using Rufus and GPT. I didn't had to change any of the BIOS settings either. It worked then as the option to boot from USB started appearing.

    By the way the FAT32 limit of 32GB is mentioned and explained here.
