I want to demolish all the data at once in Windows 8.1. But during installation, it requires some files that I don't seem to have. What to do?

Question

Windows

What media does he mean, and what files are required, please tell me? Thank you.

Answer 1

Disk/Flash drive with Windows installer.

Answer 2

Try to do the following in the command line running with administrator rights: dism /online /cleanup-image /restorehealth
If the system lacks some components, it will download them if everything goes well =), it will download them itself.
Next, try again to do what you intended.
If this does not help, prepare the windows 8 installation disk / flash drive, as requested by the system.
