comment How to reduce the size of my Ubuntu main partition to be able to install a new OS in dual-boot
What happens if you boot Ubuntu from the live DVD/USB and then use GParted which is on the live DVD/USB by default to create an NTFS partition on the disk to install Windows?

comment Video memory size should be 2 GB but shows less
This sort of thing has happened before with graphics cards. Sometimes a newer release of Ubuntu has more up-to-date proprietary graphics card drivers that solve everything. Unfortunately this doesn't answer your question for now, although maybe someone else can answer it. Also you probably can't return the graphics card since it probably works perfectly in Windows with the driver from the graphics card's installation CD. If you don't have a Windows OS, you can try returning the graphics card anyway, and of course they'll test it in a Windows PC and probably show you that it's a good card.

You're right, Sysinfo doesn't report your graphics card's memory as it should. Perhaps you haven't yet installed the driver for your Radeon HD 6450 graphics card. The command to install the graphics card driver is: sudo apt-get install fglrx fglrx-amdcccle. Then reboot the computer and check in Sysinfo again or else you can also find the same information in the Catalyst Control Center application.

Install the Sysinfo application from the Ubuntu Software Center and check what Sysinfo shows about your graphic card's built-in memory. Sysinfo is a user friendly GUI application for displaying your computer's system information.
