System reserved partition too large

I'm having trouble finding a solution to this:

The system reserved partition on my local disk is taking up about 95GB on my 240GB SSD. Of that space, 375MB are being used, the rest is empty.

From what I've read, this probably happened when I cloned my HDD with the OS on it. I'm hoping to find a solution that doesn't involve a fresh install of Windows. Is there a way to reallocate this space somehow or do I just have to start over?

Thanks

The problem is that the current configuration of your 240 GB is very awkward because the System Reserved partition PRECEDES the boot (C:) partition. So while you can shrink the nearly 95 GB SR partition to a manageable size, e.g., 500 MB (the usual size - more or less - of the Win 10 SR partition), the remaining disk-space of that partition will result in about 94+ GB of "unallocated" disk-space. Unfortunately Disk Management will not be able to extend its current partition of 128 GB to encompass that 94 GB of disk-space since DM can only extend a partition when the unallocated disk-space FOLLOWS the partition to be extended. So you would be left with about 94 GB of unallocated disk-space. Now you could create a partition out of that...

1. It would be best if you would send in a screenshot of Disk Management, including the upper portion of DM that lists the Volume, Layout, Type, etc., all the ways over to the Free space menu listing.

2. If that's not possible, then provide the following info...
A. What's the OS?
B. Describe the partitions on your SSD boot drive, e.g.,
Partition 1 is the Reserved Partition (we know it's "about 95 GB"). Check Disk Management for the "Free Space" of this partition from which we can deduce the volume of data in the partition.
Partition 2 is ? - provide the size of the partition and the volume of data in it.
Ditto for any other partitions.

If you describe the partitions, make sure you clearly show their ORDER on the drive. Capiche?

3. And, AFAUK, there's no data on the SR partition that you utilize, right?

4. I assume your HDD is serving as a secondary drive in the system so that it's connected when you boot to the OS on the SSD, right?

1.

2. Windows 10

3. As far as I know, the little data in the SR is important right?

4. I have two Hard Disks for storage only. The OS is no longer on one of them.

Now you could create a partition out of that disk-space so that at least you could utilize that disk-space to contain data/programs, etc.


There are ways to get around this using a third-party partition management program, e.g., AOMEI Partition Assistant but many users find them quite complicated to use in situations like this. But you may want to give it a try.

If you had another drive, say a USB external HDD, and could clone your PRESENT 240 GB SSD boot drive to the USBEHD so that you would have a fall-back position that would be ideal for any third-party partition management process that you undertake in the event the process goes awry.

Obviously another way to resolve this dilemma is to fresh-install the OS. I'm sure you've considered that.

I'm going to attempt the clone and management option.

Stand by...

Update: I have successfully resized the partitions using Paragon Partition Manager. I now have a 500 MB SR and 223 GB Local Disk. Thanks ArtPog :)

Good. Now don't neglect the need for comprehensively backing up your system on the 240 GB SSD boot drive from time-to-time so that you will have at hand the means to return your system to a functional state in the event of a defective drive or because the OS has become dysfunctional due to malware of one kind or another so that it's impossible (or unduly difficult) to properly restore. Now that you're adept using a disk-cloning program you can use that vehicle to create these comprehensive backups - either to a separate drive or perhaps to a partition you create on one of your secondary HDDs, assuming the drive contains sufficient available disk-space for the clone.
