The reason for "some" of us it because the existence of that partition and it being a "Primary" is it limits the number of additional primaries that can be created.

Win7 will create the 100 mb system reserved partition only while doing a fresh (custom) installation of Windows 7, where Windows 7 is installed onto a new hard disk with unallocated disk space (no partition or volume defined yet), or when the user attempts to create a new partition out of an empty drive.

Although, even with a fresh install on a new hdd, the system reserved partition can be avoided.

Hello Smitty.



Here's a prime example of what some are getting with their OEM built PCs now and if you want/need another "Primary" Windows won't do it, Windows will only create a "Logical" for a 4th, or you need a third party program to do it.

Have alook at this tutorial.

That is even a "mild" case. I have seen brand new PCs off the shelf with 4 primary partitions. The additional one was for some OEM tools. That is getting ridiculous as long as there is the 4 primary limit in NTFS.

Hello whs, that is a shame to do to people though the majority of the ones that buy OEM never know the difference and could care less if they did; it's just when they run into issues they find out.

On the other hand, with the 100MB "System Reserved" partition in place, you can install ALL of your Operating Systems in Logical Partitions. So if your first OS is C: drive and you have one optical drive set as D:, that leaves 19 drive letters to assign to additional OSs, data partitions, and external drives.

Wow, giving up 100MB of space allowing for 20 partitions ... anybody need that many partitions?

Plus you have access to "System Repair" utilities from the "Safe Mode" menu.

Cheers!

That is a good point indeed. But when you have 4 primaries out of the box, that is a real problem too.
I was trying to teach people of my computer club how to create a seperate data partition. And each time a few come forward with their brand new laptops showing me the problem with the 4 default primaries. And since these people are mostely non-Geeks, I usually end up fixing their systems.
