Windows vm in liunx from real hdd partion

i have a windows 10 laptop with Ubuntu 15 duel booted.
Ubuntu has become my normal os and i dont like switching between them.
could i boot windows safely in a Viralbox from the windows partion?
and if i wanted to could i move windows into virtual disk?

http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media Apply this to your version of windows.

Get it, create a media, and then if you unregister the license (get the number with something like Speccy first) and then install it in a VM I think theoretically it should be fine.

Just understand that it might not run as fast.

ok, thanks
i will probably do that.
but i would like to still be able to boot windows normally as well.
