Dedoimedo posted a step-by-step tutorial to installing and configuring Windows 7 and Xubuntu (14.04 Trusty Tahr) with Xfce desktop in a dual-boot
Today, we are going to have another dual-boot tutorial, which will teach you how to install the latest version of Xubuntu 14.04 Trusty Tahr alongside Windows 7 in a happy tandem configuration. I have already shown you how to achieve this kind of setup with both Windows 7 and Windows 8, using mainstream releases of Ubuntu. Now, we will diverge and test with Xubuntu, the Xfce-powered edition, which definitely merits use and fun.Dual boot: Windows 7 + Xubuntu 14.04
