Windows 7: 100MB System Reserved in Windows 7

Stupid question, maybe: where is the advantage in removing the reserved 100 MB partition?

Hummmmmm ... would an external hard drive be a quick fix for those laptops, plus allow for external storage for a Windows image?

That is more or less the answer I was looking for .. I don't care if the 100MB partition is there, I just didn't want 2 of them ..

100mb SysReserved works best for Dual Boots so that you don't lose another OS's bootability if Win7 won't start. It also places the Repair console on the Advanced Boot Tools available by tapping F8 at boot, which is a convenience worth considering on its own.

I strongly suggest you follow BareFootKid's tutorial linked to optimize the HD by Diskpart Clean All (zeroes HD), then also use his steps given to create the partition with Diskpart if you don't 100mb.

If you have a partition you don't want cleaned off the HD (and can't move the data to do so) then use the trick Bill2 posted to avoid 100mb when partitioning with installer. However, the fact that you are saving one of your partitions should preclude installer from issuing 100mb.

I don't think you have to worry about 2 of them.

Thank you for your explanation. I won't delete it since it's useful.

Is there a specific reason you are not wiping your HD before reinstall, like a recovery partition you want to save?

If not then I would copy my data off externally and wipe the HD first: SSD / HDD : Optimize for Windows Reinstallation

I mean that I will not delete the Reserved Partition from my actual installation.
I always wipe my HD before reinstall.

Reinstalls are also a good time to test your hardware: 5-6 passes with memtest86 CD, Disk Check of the HD, and full HD diag/repair CD scan using maker's utility: Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

I always do an advanced install and format the drive before installing and i do not get the 100mb reserve partition on my installs, but the ones that I do not use the advance feature, show the 100mb reserve partition I am not sure that is how it works, but that is my experience with this issue.
