<pre wrap="">Hello everyone!
After I ran virt-resize (v1.31.28) on my disk with win2012R2
(partition table [GPT]: VFAT (100M), unknown (128M), NTFS (64G))
My VM fails to boot: black screen informing that
Windows failed to start...
Status: 0xc000000e
Info: an unexpected error has occured.
After some investigations, I realized that Windows remembers the GUID of
disk it is installed to.
If I execute
>guestfish -a win2012.hdd -v
...

/bin/sh -c sgdisk -p /dev/sda

The operation has completed successfully.

The operation has completed successfully.
After that Windows successfully boots from resized image.
I suggest adding get/set disk GUID to API and to virt-resize as well.
Otherwise it is impossible to resize disks with this particular OS (not
only this one, possibly).

This is another bug: the fixed one was about partition GUIDs. <br>
Now partition GUIDs are preserved, but the OS refuses to boot
because of <br>
changed *disk* GUID.<br>
