Hi. I have been given a computer with Windows Vista Home Premium 32 bit installed. I would like to install Windows 7 Ultimate 32 Bit, but without interfering with Vista. The reason I need to do this is because the PC I was given has Microsoft Visual Studio on it, (installed on Vista) and I wouldn't want to pay for another licence just to use it on Windows 7. I used to have a partitioned (Windows 7) laptop with Ubuntu Linux installed, and I was wondering whether this would be possible to replicate, but with Windows 7 instead. In essence, I am looking for my PC to have two start up options- Windows 7 (for day to day use) and Windows Vista (for when I need to use Visual Studio.) Thanks!
