Re: How to open Windows 7 in Ubuntu 12.04 with virtualbox ?
If you're asking can you point VB to your existing Win7 install on the same PC and run that inside the VB? The answer is no.
Can I open windows 7 in Ubuntu using VirtualBox?
Also, when you reinstall Win7 inside VB, that is a NEW installation, meaning, you will have to install all the apps you want to use, and do LOTS of Windows updates to get it current for Win7.
Ubuntu 14.04, Mint 17; MS Win 8.1.
