What options you get? Could you change the drive letters so you 100 meg partition is one of those you can hide?

You could also do it by editing registry. Goto HKEY_CURRENT_USER >
Software\Microsoft\Windows\CurrentVersion\Policies\Explorer > NoDrives

Change REG_DWORD value. Values for the drives are:
  • A = 1
  • B = 2
  • C = 4
  • D = 8
  • E = 16
  • F = 32
  • G = 64
  • H = 128
  • etc., always double the last
To hide several drives, add values together: for example value 40 hides drives D and F


EDIT: Nice it worked. I've always done it with editing Group Policies or Registry.

If nobody minds..I'd like to add that... the best way to deal with that partition, is to not let it get created in first place. (This is my preference).
Evidently its a bitlocker partition. (And who uses that anyway??

The idea is to create your partition and make it active thus preventing the install process from doing it on its own and forcing the extra 100mb'er.

To do this during install...when you get to the first screen slap SHFT+F10. You'll get the command line.
Do the following...
- Diskpart
- List disk
(Determine where your installing the OS)
- select disk 0
(assuming its the drive your installing to)
- clean
- create partition primary
(use SIZE= if you want to set a specific size..otherwise omit to use the full capacity)
- select partition 1
- active
- format fs=ntfs quick
- quit
- exit

Continue install.
When you get to the Drive screen, select the existing partition you created to install windows.
No more irritating 100MB leftover.

Good advice on how to eliminate the partition during install.


The partition is aka the Recovery Partition and enables system recovery without inserting the DVD.

Another advantage with the 100MB system partition is that it is the location of the boot files and thus means that you can remove any other partition in a multi boot scenario without the system failing to boot

I have that but its 200MB, I found a good use out of it. Put programs on it:
Just google or look up "Portable programs" and put them on the partition.
This way, when you re-install windows. Just make shortcuts to the programs on your desktop.
Been doin that for a while. Doing the same thing for games but on a bigger one.

Before I do remove it I just want to make sure my system will boot? Is this ok?
