Hi. I've been looking for a few hours already on how to install Windows over Ubuntu and I find something but I'm kinda afraid to do it. So it goes like this, you simply run the dvd of the windows and after Install windows window pop ups I pressed shift + f10 and the comand prompt is up. My question is, if I delete everything on the HDD with diskpart command, will I be able to install windows? Because the most of the hdd (468gbs) were as ext4 and I couldn't change it to ntfs with gparted. So will I be able to install windows if I delete everything? or the hdd will still be ext4 ? Thank you very much.
