Last week my windows 7 operating system crashed. So I installed Ubuntu 10.04 on the partition Windows 7 was previously on. I have two Partitions, C: and D:. In partition D: I have very important data and I can't format it (I can't backup because it's very heavy ~50 GB). Now I want to install Windows 8.

I have downloaded the ISO file of Windows 8 Pro. I don't have a DVD writer or a USB device to Install this. I need to install this on C: partition (the partition on which I have already installed Ubuntu) and I need to protect the data in partition D:. How do I do this?

Edited the title, based on the comment above this doesn't seem to be a duplicate. Edit: I can't test this, but it would be nice if someone can check whether it's at all possible to do this by making Grub boot from an ISO (see 1, 2). – Karan Nov 5 '12 at 3:36
Are you able to resize either partition? – Lusitanian Nov 5 '12 at 3:49

"Frugal Install" using UNetbootin.

UNetbootin can create a bootable Live USB drive, or it can make a "*frugal install" on your local hard disk* if you don't have a USB drive. It loads distributions either by downloading a ISO (CD image) files for you, or by using an ISO file you've already downloaded.

You would create a partition and use UNetbootin to install the ISO onto that partition (instead of burning it onto a cd/dvd). I have not tried this with Windows, but with Linux...

I agree with UNetbutin, or however it's spelled, but i would like to say that there is other ways like Getting the ISO image and getting software to decode the image.
