Windows 10 free DL expires at the end of July. The install wizard gives me the following error:
“Disk Controller: Current Active partition is compressed”
The popular solution is to right click on the hard drive and uncompress. This works for most peeps, they just have to be sure that their stuff is backed up because the decompression can bugger things up.
When I try to do this I find that my disk has not been compressed.
Back to the google monster and I find a possible solution. The guy suggests that the “system reserved” partition is the culprit and needs to be assigned a drive letter so that I can tell it to relax and decompress.
read the long version here: http://borncity.com/win/2016/07/18/windows-10-upgrade-disk-controller-current-active-partition-is-compressed/
When I go to do this I find that I cannot interact with the partition in this way. I cannot assign a drive letter to it or interact with it in the same way you can with your C drive, D drive etc. This is apparently because it is an oem partition designed to stop meddling users from fiddling around.
What to do? Back to the google monkey. I discover that one can un oem the partition using a tool to change the partition style or type.
My question to you is should I be fiddling with this? Herewith a pic of the thingy that could ruin my fun.
Link to what the tool can do: https://www.partitionwizard.com/convertpartition/
I use built in command line utility to assign a drive letter.
Usually you would run
diskpart in an administrative command prompt.
First, check which volume is your system reserved volume:
You’ll get an output similar to:
Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 I DVD-ROM 0 B No Media
Volume 1 System Rese NTFS Partition 350 MB Healthy System
Volume 2 C NTFS Partition 118 GB Healthy Boot
Volume 3 NTFS Partition 450 MB Healthy Hidden
Volume 4 F NTFS Partition 931 GB Healthy
Volume 5 D NTFS Partition 931 GB Healthy Pagefile
Volume 6 E NTFS Partition 931 GB Healthy Pagefile
As you can see, on my system, Volume 1 is the system reserved. It will most likely be the same for you.
Then the following commands should work for you:
select volume 1
Then when you’re done fiddling, you could use the following to remove the drive letter:
select volume 1
It’s also really strange that any of your drives are compressed…
Thanks very much! Will try that route. Have been fiddling with the tool and realized that while my disk manager won’t less me assign drive letters to the oem partition, the tool will. From what I have read, fiddling with the drive can cause boot problems.
Reporting back. The partition was indeed depressed. While alleviating its condition I got this message which I chose to ignore. Windows update persistent likes what I have done. And wants to bring Windows 10 over to play. I just hope that boot thing doesn’t come back to bite me.
heh, even if you wipe out the boot it can easily be re-created.
