Need to shrink my system reserve back down

Specs: Windows 7
In Windows 7, how do I shrink my system reserve without harming anything? I kept getting errors when trying to back up my computer. My backup (including a disk image) needed about 550 gigs of space, but it kept failing. Even though my backup destination drive had 1.5 gigs free.

The problem was that the little 100 mb sys reserve drive needed 40 mb free but only had 10 mb free. So it couldn't handle the shadow copy and my attempts to create a disk image kept failing.

It took 4 days of reading through forums and I ended up extending the sys reserve to 450 gigs so I could get enough free space on it to do a disk image for transfer to a new disk.

I finally got my back up and my system image and I transferred my system image to my new larger drive. However, now I've got 2 gig C drive with a 450 gig system reserve volume and 449 gigs of that is wasted and useless. That’s a lot of space just sitting there doing nothing. It would be nice to be able to get that space back to the C volume and off of the System Reserve volume.

I tried shrinking it the first time around after making my new disk, but it made my system unbootable. So I had to take another 2 hours and recopy the disk image to my new drive again and now I'm back where I started. A nice new hard drive with 450 gigs of it wasted because it can’t be used.

Windows Disk Management will still let me shrink the sys reserve but I don't want to mess up my ability to boot my computer again.

Any help would be appreciated.

"I tried shrinking it the first time around after making my new disk, but it made my system unbootable."

Of course because you created raw space between it and the boot partitiion. That is why your booting failed.

We image pcs all the time and have never had issues with the system partition affecting the image nor backup. But then we don't mess with putting files there or anything.

This would have been a good guide for you to follow

Given your present situation I would suggest you shrink your system partition to the proper size, wipe out the c: partition and then clone the original c: from the old drive to the new drive expanding the partition clone to the rest of the disk..

If 100 meg drive is needed, you have way too many other issues. You have to get more like 75% of the drive free.

By the way, don't mess with that reserved space.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

Because there is no more room.

First do a copy of the SR partition, in case.

Then download Diskkeeper trial, and move all files to the head of the partition.

Then shrink the partition and expand C into its place.

The problem now is that the new head of the C partition doesn't contain the PBR. So for that, you probably have to image the C partition as it is and then copy it back to the new expanded partition space.

If that fails, you probably can reset the boot sequence using a linux disk with mbr and partition utilities (EaseUS partition manager, eg). I think you're better off doing all the partition work from outside Windows.
