Format main hard drive to NTFS

[JimJam22]

Hi, I was trying to change my operating system back to windows with a bootable usb drive, but apparently I need to format my hard drive to the NTFS format. I only have 1 hard drive but i'm a bit stuck because I can't figure out how to do it. I tried to format it to NTFS in the Disks application but i got an unmounting error.

Any help is appreciated, I'm not very experienced with linux

Many thanks.

I believe you can partition and format the disk using GParted.
The disk being worked on must not be in use at the time - thus the unmounting error.
A 'Live' disk image on USB of either GParted or a Linux distro which includes GParted should do the trick.
Simply boot the machine from the Live USB image and start the GParted application.

GParted -- A free application for graphically managing disk device partitions

gparted.org

The 'Live' image (.iso) of Linux Mint 19.3 includes GParted. Or you could download the GParted image and create a 'bootable' USB from it.

knoppix is one live os that can be used from a usb that has GParted on it
