Deleted Logical Drive - XP will not boot

Greetings,

I added Linux Mint as a dual boot to a Dell E520 with Windows XP.

I intended to add an old hard drive to the system and intended to keep one of the partitions - deleting the other. What I accidentally did was to delete the logical drive from the C:\ drive which contained Linux. Now I am unable to even boot into XP. On boot it stops at "Grub Rescue" and I have no way around it.

Please help.

Thank you.
