Well,

I think that I've found the solution: the problem was that iso fiile was in the very root partition, because of that, Liveinst refused to unmount it. I've verified moving iso file to another partition and this error went away.

Hi,

I have the following options in "/etc/grub.d/40_custom":

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

menuentry 'Live Fedora 23' --class fedora {
  set isofile=/boot/Fedora-Live-KDE-x86_64-23-10.iso
  loopback loop (hd1,gpt3)$isofile
  linuxefi (loop)/isolinux/vmlinuz0 iso-scan/filename=${isofile} root=live:CDLABEL=Fedora-Live-KDE-x86_64-23-10 rootfstype=auto ro rd.live.image quiet  rhgb rd.luks=0 rd.md=0 rd.dm=0
  initrdefi (loop)/isolinux/initrd0.img
}

It boots fine, but I cannot install it says:

"blivet.errors.DeviceError: ('cannot replace active format', 'sdb3')   "

/dev/sdb3 es my current rootfs....

I've reported the bug https://bugzilla.redhat.com/show_bug.cgi?id=1284187

In the mean time, please could you tell me that if a grub2 misconfiguration in 40_custom file?

Thanks in advance!
