Uninstalling Linux need help bad

A while ago I split my D drive in to two sections so that i could install linux on one section and have a dual boot type deal. I haven't used it much lately and decided to try and delete linux and merge those two sections of the D drive back together. I used partition magic, and tried to do some research but could not find much help. So in partition magic i used the configure task to configure the linux section into NTFS to match the other part of the D drive, then i figured i'd just merge the 2. well the computer rebooted and said it configured it, but now when it boots up i get the black screen with just the "grub>" prompt and no idea what to do. I can easily admit i had no idea what i was doing and still don't and in my impatience thought i could figure it out. I'm very sorry for bothering with this, but if i can get any help i'd greatly appreciate it. thanks. Im running a sony vaio desktop with windows xp sp2

 

im so lost right now, i can't even figure out how to boot from the cd-rom. i F2 into the set up and it's all chinese to me. im trying to boot from a disc so i can delete the grub boot manager and just can't figure it out. im sorry for whining. i have no clue how to tell it what to boot. i downloaded that OS boot manager file and put it on a cd and can't get it to load. just keeps taking me to the grub screen.

 

ok i finally got into windows using

grub> chainloader +1
grub> boot
