Massive problem after Partitioning C: Drive

[The Black Death]

I partitioned my drive the usual way (Right click on - my computer - etc)

I went to re-boot and got the -BOOTMGR, press ctl alt dlt to restart- error

Basically, I made a small crappy partition, which did not even name or assign a letter to, and the computer decides that it is a good idea to boot up with that one instead of the C: Drive which my OS is intstalled on causing this error.

I basically need to now how I can get it back to normal (And no I have never made a system restore point, but i have learned the lesson now). I need to know how to boot up using C again, and then how to delete this hellspawned partition.

I AM ABSOLUTELY LOSING IT BECAUSE ASUS HAS THEIR OWN BIOS AND I CAN ONLY SELECT TO BOOT FROM THE HD NOT DIFFERENT PARTITONS, ALL THE DATA IS STILL THERE, I JUST CANT GET IT TO BOOT THE C DRIVE BY DEFAULT!!!!!!!!!!!

The windows 7 64bit disk is in the drive, I have tried repair, system restore, and going to install windows where i can neither delete or format the partition.

I'm tearing my hair out here on this stupid Mac I am forced to use. lol. Whoever can help me will be in my eternal gratitude!!!

If you do reply please give DETAILED INSTRUCTIONS!!! This is the dark side of the PC that I have never ventured to before apart from one time before this to overclock my CPU. Act like I'm an 8 year old.

Specs: Asus motherboard (Brand new one with fancy BIOS), 16Gb ram, GTX 580 3GB, 1000W power supply, i7 2600k overclocked to 4.4Ghz

THANKS!!!!!!!
