Upgrade Windows 7 to Windows 8 without DVD/Penrive

Hello!
I just want to upgrade and format my Windows 7 to Windows 8, but i don’t have DVD and don’t have enough pendrive with space to do that.
SO it’s possible to upgrade without DVD/Pendrive? Of course without paying…
Thank’s!
Answer #1
Not as far as I know of. But why are you making such a fuss about it?
Is it really that difficult for you to buy some blank DVDs or a 4GB flash drive?
These things are very cheap (And widely available!) so I just don’t get what the big deal is!
Answer #2
My DVD reader is damaged but what about pendrive – i have 4gb pendrive but windows 8 have 6 gb i think…or i readed not so good.
Answer #3
So? Any idea? I have only 4 gb pendrive
Answer #4
An untouched Win8 copy will fit on a 4GB pendrive just fine!
Answer #5
So just download normal version of w8 and it will be fit on 4gb?
Answer #6
Yep.
