Windows 7: Boot Folder

Hi
Today I found out that there is a Boot folder and a bootwiz folder and a file called bootmnr on my D drive.
The only operating system ist Windows 7 Ultimate, which is installed on C.
Shouldn't be those folders and files on C? Are they on the hidden 100MB partition (if yes how can I see them)? Or can I just delete all those folders and files on D?
Thanks

It would help if you posted a picture of your Disk Management. The 100MB partition usually contains the MBR. If you delete that, the system will not boot any more.

Here's the screenshot.

The 100MB partition does not seem to contain the MBR. My guess would be that the OEM put some tools there or the sole purpose is for Bitlocker (which is not a Home Premium function anyhow).
The fact that D is also active inicates that there is some sort of boot stuff as you have stated earlier. No idea how it could have ended up there.

Actually if I assign a Drive letter to the 100MB hidden partition I can see the Bootfolder (see attachment). The recovery Partition was made by me (Initial Image of Installation). It's not a OEM Installation it's a custom built PC where I did all the installations.
Still wondering if I can just delete these files on D....?
Thanks again

Since the 100MB partition is not "active", it really does not serve any purpose.

Yes the 100MB is more or less a backup with bootfiles and used mainly for Bitlocker.
I ran EasyBCD and found thsi info:
There is one entry in the Windows bootloader.

Default: Windows 7
Timeout: 30 seconds
Boot Drive: D:\

Entry #1
Name: Windows 7
BCD ID: {current}
Drive: C:\
Bootloader Path: \Windows\system32\winload.exe

I am confused now.....
I mean everything works, but I hate to have any boot files on D.
Thanks
