Win8.1 OS (C:) partition refuses to shrink!
#13
I'm a bit late to the party here  ??? , but going to offer a few thoughts.

On the 250GB SSD is the following:
900MB recovery partition
100MB EFI System Partition
231.78GB OS (CSmile NTFS

I need to shrink C: so that I have some space for an LL2.4 reinstall. The shrink tool under Disk Management doesn't seem to work, or at least is indicating that no space is available for shrinking.

As N4RPS and Wirezfree pointed out, if Fast Startup is not disabled then Win 8 is likely hibernated when "off" and that would cause problems when trying to use GParted.

I don't know anything about Win 8, but if it also uses a paging file like Win 7, that could have played a role too.  (More so when trying to shrink from Win disk management, because I don't think GParted is affected by it.  Although I could be wrong on that.)  5 years ago (when I last dual-booted with Windows), I had to disable the paging file in order to shrink the Win partition in disk management.  After shrink, just enabled it again and it got put in a new spot on the newly shrunk partition.

I downloaded the free version of Minitool Partition Wizard and it worked a treat in shrinking the drive by 50% & healthy rebooting.

Best guess is that since the tool is designed for use with Windows, it knows how to get around the hiberfil.sys file and/or the paging file problem.

From what I've read, Win 7 should be installable in UEFI mode, but under a few conditions:
  • It must be a 64-bit version
  • It must be a full "Retail" version of Windows; or an OEM version that was already installed to that particular computer in UEFI mode.  If it's an OEM version that was installed to computer in CSM/Legacy mode, it must be installed as it was originally.  If from a different machine, it won't work either (maybe not in any mode).
  • The hard drive needs to have a GPT partition table on it before you attempt to install to it.  Windows (7 and above) will install to the drive based on the type of partition table it detects on the hard drive.  Windows will only install in Legacy mode if it detects and MBR drive.  And it will only install in UEFI mode if it detects GPT partitions.
