Windows 10: System Reserved Partition Seems Excessive

Hi all,
I just went from a 500GB SSD to a 1TB SSD. I migrated the Drive C from old to new SSD using the Samsung app. I have been puzzled by the relative lack of space on the resulting new SSD. Here are the results of checking with Win 10 Disk Management routine:

Total SSD size: 931.51 GB NTFS
First Partition: 698.32 GB NTFS Drive C:
Second Partition: 482 MB Recovery No drive letter, no information
Third Partition: 232.72 GB NTFS Drive P: System Reserved

Doesn't this third partition for System Reserved seem excessive? How much do I really need with Win 10 Pro? I would like to recover any extra disk space from this partition and add to the first partition. I may have to reformat the entire SSD and do clean reinstall of Win 10 Pro?

All insights appreciated.

:)

 

Recovery Partition vs System Reserved Partition


Thanks for all the info guys.

Both original & target SSD's are listed as MBR as opposed to UEFI. I may have created a partition unknowingly in getting the original/new unformatted drive recognized, but I don't recall taking any steps that Windows did not step me through.

Not that an upgrade to WIN 10 Pro is contemplated, but I suspect that having no System Reserved partition will not allow that to happen, after seeing how the original WIN 10 upgrade created a problem for some WIN 7 users that had a smaller 100mb vs 500mb System Reserved partition.

 

W10 System Reserved Partition Error

Hi,

Have you tried all the suggestions above? If not, we suggest the resolution provided above. We also suggest that you follow the steps on this link:

“We couldn’t update system reserved partition” error installing Windows 10.

Let us know how it goes.

 

"Windows 10 couldn't be installed - we could update the system reserved partition"

I think you mean "could not update", not "could".

Suggestions:

• Disconnect any other hard drives.
• Run chkdsk /f on the System Reserved partition. You'll have to do this from the CMD prompt in Repair Mode.
• Initially there were reports of some System Reserved partitions being too small for the upgrade. Search for details if the first two suggestions fail.
