I tried deleting Linux partitions

[Kajcha]

I was wondering if anyone can help me with my problem.
I installed Zorin OS 5.2 (Linux) along-side Windows 7.
And then i found out about Windows 8 Developer Preview, and decided to give it a try.
So now i want to delete Linux and Dual Boot Windows 7 and Windows 8 DP.
But there is no Uninstall option in Linux. I tried deleting Linux partitions (theres 2 of them)
and when i restart, it shows me the black screen, saying "Error: Could not find partition"
"Grub help: _" Something like a command prompt. And then i can't boot into Windows 7.
I was recently reading something on the internet and found out that Linux Grub Boot Loader messed up with MBR on my Windows 7 partition.
I had to install Zorin OS 5.2 again, just to be able to boot in Windows 7.
If anyone can help me with this problem, I would appreciate it, or at least help me with making Windows 7 primary OS to boot in.
