So my friend's computer recently got some corrupted OS files, and i wanted to help him reinstall windows 10. I formatted the drive as it was for no use, and proceeded to create a bootable USB device, which his computer wont recognise. When i plug it in, it doesnt do anything, and when i attempt to create a new boot media, it simply goes into the USB and wants me to select a file, and it doesnt even let me choose the exe file anyway. So i was wondering if i can connect his drive to my own computer and run the ISO installation file on there without damaging my drive with windows 10?
