Can we add an Ubuntu partition to a drive containing a Windows 10 storage pool?












1















About a year ago we had set up a Windows 10 machine (for gaming) with a 250 GB SSD and a 3 TB hard drive. This machine should now also dual boot to Ubuntu. No issue to shrink the SSD to hold Ubuntu - that went smooth.



But from Ubuntu we have no access to the 3 TB hard drive. The plan was to leave 1 TB unpartitioned for later use in Ubuntu. However for reasons obscure to me Windows 10 did not create an NTFS partition but it had created a single 2 TB "storage pool" on that drive instead.



Of course we did not hibernate, fast boot is turned off, no encryption involved. Still, from gparted the whole 3 TB drive shows up as unknown 2.73 TB:

But the Windows partition manager can not see 1 TB space:



enter image description here



It appears that Windows had greedily grabbed the whole drive when we wanted to give it a partition only.



Is there any solution for this? Is it at all possible that we add an extra Ubuntu-accessible partition to our drive?

  • Sounds like this should probably be fixed on the Windows side. You might be better off asking on Super User instead.

  • @terdon yeah, that was what I was thinking too in the first place but I may likely be able to grow my "pool" to use the whole drive. So it is not really a Windows issue. From what I learned it will then be impossible to shrink it again after that. Of course, why should Windows support a non-Windows partition? I then decided to come here first to ask in the hope somebody had the same issue before. A Windows user may not be affected by this so much. If the answer is no you can't do that, then at least I can stop searching, and format the whole drive from gparted (after backup).

  • I'm just assuming this pool thing is a Windows feature and not LVM. If I'm right, doubt we'll be able to help. Since they have both Linux and Windows folks on Super User, I figure your chances are better there.

  • @terdon: added some shots - if nobody gets here by tomorrow I will delete this and ask the Windows folks.
