I am in a Linux tinted Hell

I had a post in here earlier about freeing up some space on my system by removing Fedora Core 4. It was a mere experiment and I wanted to see what it was like (much like those that try weed), but it didn't go very well. I didn't quite get into it.

So I decided I wanted to remove it and free up like 15GB of logical partitioned space with Norton's MagicPartition (much as I had used it to create and partition for it). Everything seemed smooth, delete the info in the logical drive, merge it with the Primary drive. Shouldn't be any problem, duel boot screen will go away and I'll have my Windows again. My system reboots to do the changes and I get this bad feeling in my stomach, so I hit any button I can to stop it (it said hit any key to abort), but my keyboard wasn't working. I should have taken that as a sign. When the system restarted, I was in Grub. I have no idea how to use Grub. I'm stuck in this Linux tinted Hell and I don't know what to do.

If anyone can help me, please, for the love of God, do it. I'm using a Dell and they didn't give me any sort of restore disk, just a minor partition on the drive that has the stuff to do it. Not that the disk would be of any help because I wouldn't know how to load it on Grub anyway...

Dells should either have a restore point on harddisk that you can access with CTRL+F11 or some other key combination before POST screen, or restore CD. Of course this means that you'll lose everything you have on the HDD.

support.dell.com and look up the manual, it should have info how to reach the restore partition (Unless you've removed it)
