Windows 7: If i use my ubuntu disk and set it up would that save win 7?

I really need to know this because i want both .

Yes you can Dual Boot Windows 7 and Ubuntu. without loosing Windows7, their are loads of other tutorials to help you do this too, just google Dual Boot Windows 7 and Ubuntu. I would use Linux Mint KDE over Ubuntu anyday, but I guess that is a personal preference!

Why not install Ubuntu as a virtual machine? It runs great under both VMWare Player and Virtualbox...which are both free. Give it a shot, I haven't dual booted in a long time.

Virtual Box is always slow for me on Windows, wile running Linux ect in it, I even give the guest 2 or 3 GB Ram, and let it use 2 processor cores, but my cursor still draged across the screen, as for VM Player, Ubuntu 11 would not work properly because VM Player could not support some features, who knows maby I needed to install an AMD Video Card driver or somthing in Ubuntu for it to work properly? But I gave up on it, was nothing but a pain in the you know what. But who knows maby it runs better on Intel Hardware?

I have a dual-boot with Windows 7 and Ubuntu 11.04 and it works fine. If you follow the tutorial below and use Wubi Installer, it will be installed like any normal program in Windows 7. That way, you can also uninstall easily.

When i was using Ubuntu 11.04, I installed Unity 2D with the following
To install Unity 2D, type the following commands in a terminal:
