Windows 7 - 200mb partition?

I had Windows 7 beta 7000 on C partition,and of course,extra partition 200mb big.After that I messed up something,wasn't able to boot from that partition and because of that I installed Windows 7 again but on D partition,and without formatting that C partition or that new created 200mb big partition.Now I had one more partition free,and I want install build 7100 on that partition,
so my question is may I format that 200mb partition what was created with first installation of Windows 7 together with that first,now nonbootable partition of Windows 7?

Pretty sure you will find the 200mb is listed as System in Disk Management.

Post a screenshot of Disk Management. like this:



If that is the case, and you want to remove it , as well as stop 7100 making another - you need to make D the System partition.

any reason it does that in the first place?

I would have deleted that failed install partition before doing the new partition.

Yep,I found it,but my question is(knowing that in that partition are system files),may I format it together with first nonbootable instalation without consequences for another,working installation of windows 7 which I made after this.
If there is no consequences,I would certainly delet it.

You can delete that partition if you are not booting an OS from it. Correct me if I'm wrong, but you are booting from a good install on D:\ ?

Yes,I also believe that this partition is not connected with this another new Windows 7 partition from which I boot now,but I needed confirm.I wasn't sure if system files for both partitions are inside it(inside 200mb) or this new D partition has it's own system files stored all inside D.
So,thank you very much,after all,I actually don't need neither that D partition,I just want to copy some files from it after I install 7100 (or maybe even 7127,I'll see),and I believe I can copy files from it when I take ownership from new 7100,even if the old one is not bootable.
Once again,thank you all.
Cheers

Tried to install 7 on a hard drive with no partitions.
It wanted to setup the disk with a 100mb partition probably to use it as a dynamic disk. I hate dynamic disks. Serve no real purpose at all.

Had to use an XP CD to create partitions. So lost only 8MB and not 100MB.

dont know why MS likes setting up new hdd's as dynamic disks.
After the database table got lost while setting up a 1TB disk.
I always use simple disks....

The 200MB partition (system partition) is tied to one install. They are not mixed or combined. So deleting one does not badly effect the other. It is merely what each particular install sets aside.

Cheers!

And the 7 install runs fine with only 8MB allocated for that system partition?
