Dual boot w/Win7...Help removing Xubuntu to install Linux Lite 2.0

[modeltweaker]

My laptop is dual boot with Win7 and Xubuntu. I would like to remove Xubuntu and install LL2. Not sure what to do. I don't want to mess up the Win7 system as my daughter needs Office and Photoshop for school.

When I installed Xubuntu I had 30gb free in Win7. I told the Xubuntu installer to use 12gb. When it finished Win7 had 8gb free and it used 22gb. Win7 is now a pain with very little free space. So...Could I allocate less space for Linux Lite and grow the Win7 partition a little? Is there a way to uninstall Xubuntu? What happens to the boot loader in all these changes?

My drive layout is below. Any advice would be appreciated.

Thanks
