I have a Dell workstation, bought it on Ebay for a couple hundred dollars, had an EE quad core processor, which was an upgrade to my own machine. So I slipped my old processor into the dell, and it works fine. The machine came with Ubuntu 12.04, and worked nicely before and after the processor swap. Now I'd like to load up win 7 and pass it along to a friend who needs a machine. But I'm having a bad time getting win 7 to install. So far, I have been tryng to use a dell oem full install dvd with sp1. When I boot from the dvd, it does the initial loading of files, then either reboots the computer, or freezes at some point while building the splash screen. I have tried three ways: first just straight over the ubuntu partitions. Next, I booted from gparted and wiped all the partitions. And lastly, I again booted from gparted and made the whole disk a single ntfs primary partition. But the results with the win 7 installation are the same, as described. Does anyone have any insight into where I might be going wrong? Thanks
