Windows 7: Removing 100MB system partition - no re-install needed

You should be aware that the 100MB partition also contains software to assist in recovery should your system become unbootable. You should stop worrying about trying to remove it and be glad that it's there. I will never understand trying to remove something new just because you can, even if you don't fully understand it in the first place!

In the times I've tried it, if you format the new OS partition from the install disk (don't just install to unallocated space but create and format it) and then point the installer to the partition you just formatted, it won't create the 100MB partition.

Yea, it does certainly serve a purpose to have the WinRE on another partition. Pre-Windows 7 I've used the setautofailover.cmd command to move boot.sdi and winre.wim files to a separate partition for safety's sake (in case of complete OS corruption).

But I can also understand wanting to not have it. Each user has their own preferences.

Is WinRE inside that 100mb partition?

Hmmm. In the way Windows 7 sets it up, it doesn't appear to be.

It is...that's the point of the partition being there. It also handles BitLocker encryption. Best advice, suck it up and leave the partition there. It's not killing you.

Hi Zr,

LOL . It was a rhetorical question.

A lot of people think it is in there - I have no idea what gave them that impression.

Steve Balmer is a cool guy.

I don't think even he could fit 164mb Winre.wim in a 100 mb partition.

I could be wrong.

On mine, winre.wim and boot.sdi are hidden away on the OS partition. Sounds like MS did a half-a$$ed job at protecting the Recovery Enviroment if they didn't put those two files on the System Reserved partition.

I copied winre.wim out of there to take a look at it. It's 160MB. Hmmm. Remember somewhere between beta and RC, MS announced they didn't need a full 200MB and started making the System Reserved partition 100MB instead of the original 200MB? I wonder if they originally put winre.wim and boot.sdi in the System Reserved partition but then changed their mind. I guess I could reinstall an older build to check, but it really doesn't matter anyway.

Be a hell of a squeeze even with 200mb - the boot citical files are in there as you can see in your screenie - add 164mb to that ?
