Hi Ed -
Please post up a screenshot of the contents of the OEM partition by unhiding Hidden files in Control Panel>Folder Options>View, then in Disk Management give OEM partition a drive letter. Use the Snipping tool to post screenshots of the full maximized contents including any subfolders contents.
If you have Partition Wizard home edition, you can rightlick OEM partition to Explore contents, expand subfolders within the maximized windows to capture a snip.
What was the original preinstalled OS which came with the machine? When was the Recovery partition removed?
Check also if you have the Repair console on the F8 Advanced boot tools menu by tapping the F8 key at bootup. This means the OEM is acting as System Reserved partition. If not, we can help you construct a System Reserved Partition in its place.
