I have a laptop, Dell XPS 13, with a bitlocker partition that I want to shrink. I tried the usual shenanigans, disabling the page file, disabling hibernation file etc.

This stackoverflow question seemed to offer some solution; turn off the bitlocker encryption.

However I have the windows 10 home edition, bitlocker options are nowhere to be found. This is to say, Dell preinstalled some bitlocker partition I cannot decrypt => therefore I cannot resize it.

Gparted etc. are pretty useless as far as I know with fully encrypted paritions and I don't really know what to do anymore.

Besides just reinstalling Windows, is there anything else I can do to resize the partition ?

  • So, you're saying that you've got Window 10 Home edition and you also have bitlocker??? Is it possible that you're mistaken about having Home edition or having a bitlocker protected volume?

  • I'm sorry if I was being unclear, I have windows 10 home edition, and a bitlocker protected C drive. (aka Disk Management Notes that its "Bitlocker Encrypted") Dec 10, 2016 at 14:54

You can do it from the Windows PowerShell (using the command line), here is how:

So... I have no idea how... but shrinking it suddenly worked ?

I have ran some defragementations using "Auslogics Disk Defrag", but that program didn't seem to do the trick. Other tools also didn't give the desired outcome, but now, after booting a couple of times again, it suddenly just worked.

Thanks for the effort everyone.

  • I'm having this same problem but unfortunately "booting a couple of times" didn't make it suddenly work for me :(

I have the same issue, it appears that Dell have pushed an image that is already encrypted. I had to go into bit locker and turn bit locker on. I then turned it off and it started decrypting the disk.
