I will anyway.
What it is saying is that your current install seems to be too bad to return to OEM state.
How does the owners manual suggest you recover it to OEM or as bought state? Sometimes they call it system restore or recovery.
Some systems need you to create new disks before the disaster happens. Some even expect you to purchase the disks from the OEM. Dell has in the past offered a way on their systems to recover it. Some Dell systems I believe need you to press the F8 key sort of quickly at the start of boot. Too late and you get the Microsoft version of F8. This is one version but read the owners manual (online) to see. http://en.kioskea.net/faq/7319-dell...
When you get it working again be sure to apply the latest Microsoft updates and if not already installed get a good security suite. At least get Microsoft's security essentials or another complete suite.
You are not lost yet.
