I have a lot of junk in my lap Both in Ubuntu as well as Windows 10. I want to factory reset my lap n remove both the OS and install windows 8. Can anyone help?

The simplest way will be to have a CD/DVD/USB of the OS you want to install and use that to do the wipe and reinstall.

I agree with webworkings. You need to wipe all the partitions and you're fine to go. If you want to reinstall the dual boot structure do install Windows first, then install Linux.
