Re: Install Vista - Inspiron N5110 (after Ubuntu 11.10)
Alternatively if you want just Vista, follow my wiki A Clean Install of Windows Vista. p.s. would you not be better with Windows 7 opposed to Vista? For development purposes, I think it will be better to work with 7 as 7 is more commonly used than Vista.
If the machine has a Windows 7 COA with a readable product key you may use retail media and phone activation. In this case I refer you to my wiki A Clean Install of Windows 7 and Microsoft Windows and Microsoft Office Downloads.
