I know this question has already been adressed in several posts like here: unable to satisfy all constraints on the partition or there Gparted Error "Unable to satisfy all the constraints on the partition". And I'm willing to use the fixparts software, but it says on every answer that I should be very careful using it and I don't really understand careful about what exactly.

I have a dual boot Ubuntu 14.04/Windows7 and recently freed some space in the Windows partition to extend the Ubuntu one (using easeus). After that I used the Boot repair tool to fix the boot. Finally, I can't reallocate it since Gparted is seeing the whole SSD as unallocated...

Here's my gparted error message: enter image description here

Here's the fdisk -l return

I read on some posts that there should be some space (usually 1 or 2 Mb) between each logical partition to store the EBR. Unfortunately I don't know if this is really my problem nor how to fix it safely without Gparted.

I don't really know what more to add. Please, let me know if I'm missing something here and if "Fixparts" is the way to go.

Thanks!

    fdisk doesn't support GPT partitioning. You have to use gdisk to get accurate info for sdb and sdc, however that doesn't explain what happened to sda and why gparted refuses to handle it. I suggest that you begin by booting into Windows and running Chkdsk on all your windows partitions as suggested by @oldfred in a comment on this post: askubuntu.com/questions/611892/… You don't mention your version of Windows but you should also superuser.com/questions/957081/…

  • what version of gparted are you using?

  • Do you have ~250 GB of free space on one of the 3 TB drives you have installed?

  • Hi! I solved my problem! So: 1) Dualboot systems requires an MBR partition. Hence fdisk and not gdisk. sdb and sdc are only data drives (and they both are housing a 3T Basic Data Partition). 2) Windows7, beginning of the second paragraph :) 3) My problem came from the Swap partition sda6. Too close from the previous one. It became "obvious" using Fixparts because the partition was omitted. So I rewrote the MBR partition without the Swap using Fixparts again. From there Gparted (v0.18.0) was back and allowed to modify the partitions with a bit of work. Thanks for all the help!
