I am in huge need of installing 64bit os. My CPU is 64bi compatible, and i have the 64bit files. The problem is, im not quite sure on whether i can just mount the .ISO and run the setup. I do not mind loosing my files, but i do not have a USB drive or a DVD available!

One possibility is that you could use native VHD boot. See the video here where he walks through performing VHD boot with Windows 7 and you’ll notice that he is able to get the native VHD boot environment up and running without separate installation media. Bear in mind that though he is using ImageX with Windows 7, for Windows 8 you would want to use DISM to apply the image.

With that said, I would recommend getting a USB stick to perform your installation over VHD boot. While VHD boot is very stable and usable as an everyday environment, it does add a layer of complexity.

I think i made it perfectly clear that I need to install the OS WITHOUT a usb drive. My question is, can i just mount the iso and simply install?

Usually all operating systms come in a way so that they can be mounted on a DVD

 



No, you can't. Mounting the ISO happens in Windows with 3rd party software while installing Windows happens by booting from a DVD/USB drive.
