200 Mb Partition Needed Or Not ?

I've installed windows seven just before Christmas,and it served me well till middle of February,when "I had to explore it a bit more".And of course,I have deleted something and there was no way to boot win 7 up again.It booted correctly,but after"starting windowws" everything stopped.I tried to fix it,but no,and even worse,I was kind of short with space on C partition(cos me idiot,of course,made it just 30 gigs),and have turned off system restore.

Just for the record how smart I am,I made win 7(beta OS ?!?) my primary and only OS.

I had to save my files and didn't reformat C partition right away cos I planned to reformat it after I take the ownership and back up my documents.

So,I have installed windows seven again on E partition,which is now,after reassaining letters,C partition.And literally,now I'm having dual boot,both windows seven,one is working and one not.I have backed up my files a long time ago from now,but still didn't format that partition,and today I decided to do it.

And here is what I don't know.

When I created my C partition for Windows 7 first time,I got an extra 200Mb partition,but when I've installed Windows 7 second time on that "E"partition,I didn't have to make that 200Mb extra partition.

And now I wonder should I merge that 200Mbs with another partition and format them together,or do I have to leave it where it is?

I'm not sure,and I don't even know if another win 7 installation is using that 200Mb partition or not?

What should I do?

And one more thing,I have deleted windows folder from ex "C" partition couple weeks ago.
