Windows 7 Insists on 100 MB or 200 MB system partition
Posted 07 March 2009 - 09:19 PM
The main reason Microsoft created a dedicated System partition is to have a clean boot architecture for storage drivers that transform the OS partition and is required during booting. So, for something like bitlocker, this simplifies things since the bootmgr can come up in the regular way; load a simplified version of the bitlocker driver that facilitates booting the main OS and go ahead and load the encrypted OS volume. The same applied for VHD boot.
If you already have an active partition from another OS (like Vista) no new partitions are created.

If you started with partitions already setup, then it will not create this partition.
I've never had the 200MB partition, although when i install Win7 on my sister's and her boyfriends laptop... it always creates it, but never on my laptop.
However, if you format your drive using the GUI format, then Windows 7 will take the liberty to create the system partition.
See first post on how to avoid this with diskpart.

Correct - if you pre-partition, Win7 won't create the 200MB (or, 100MB in later builds) partition. However, adding bitlocker later will be more of a pain, for one of the downsides. However, if you never plan on bitlocker for your machine, nor plan on booting with an EFI bios (and you'd know already if you were or not), you don't absolutely need it (the boot data can be stored on the same partition as Windows, but recovery may be harder later if something bad were to happen to the filesystem of the root partition).
Great points. I'll link to first post.

BTW, since I had deleted that protected system of 100mb during installation stage, can I call back that again without reinstalling the Window?
Now my 500gb have 3 drives:
100mb (non protected because I deleted it off)
99Gb (WIn 7 OS C drive)
400 Gb (E drive)
