Make a Hard drive install windows on itself? (Yeah it sounds stupid.)

Okay... Because im stupid and low on money, i only have a 4GB USB. I want to install Windows 8 on a seperate harddrive. My problem is that windows 8 takes 4,1 GB space to install :/

My question is: Is it possible to participate space on the harddrive to put all the install files, and make it install Windows 8 on the other participation?

If not, is there anything in the install files i can delete to make it fit on my USB?

(Btw. sorry for by bad language... Im 14 and live in Denmark, so its not like i am a genius.)

If you already have windows installed you can do this.

1. Download the ISO disk image from:

http://windows.microsoft.com/en-US/windows-8/iso?SignedIn=1

You can then mount the disk image using a utility like Daemon Tools, Alcohol, MagicDisc or some other tool of your choice.

Warning: DO NOT run the auto run installer. It upgrades your system in place with no option to install and run from another partition.

2. Look for the folder name “sources” on the virtual install disk you mounted in step 1.

3. Run setup.exe from that folder and follow the steps to install on another partition.

 

Thank you. You are my new god :-)

How do you get that it takes 4.1 GB to install? My 64-bit Windows 8 Pro ISO is only 2.69 GB and I have it mounted to a USB flash drive as well and it is still 2.69 GB. 32-bit ISOs would be even less in size.
