Failed to restore partition with CZ customized zip

[kirapangzi]

Hi,
I'm using CZ to do these steps, to achieve restoring partition without USB:
1, save a partition image of /dev/sda5,
2, customize this image to a bootable zip file to restore /dev/sda5,
3, unzip the zip file on /dev/sda6, and add a new grub2 boot option to boot from /dev/sda6,
4, boot from sda6, and do the restore process.

However, after CZ boot from /dev/sda6, it haven't restore /dev/sda5. I enter cmdline and can't find any image files in the /home/partimag dir, seems to be the /dev/sda6/home/partimage haven't been mounted to the live debian's /home/partimag.

Here's my grub boot parameters, which is refer to: http://clonezilla.nchc.org.tw/clonezilla-live/livehd.php

menuentry "Clonezilla" {
insmod xfs
set root='hd0,msdos6'
linux /live-hd/vmlinuz boot=live live-config noswap nolocales edd=on nomodeset ocs_live_run=\"ocs-live-restore\" ocs_live_extra_param=\"-g auto -e1 auto -e2 -c -r -j2 -p true restoreparts 2015-01-30-07-img sda5\" ocs_live_keymap=\"\" ocs_live_batch=\"no\" ocs_lang=\"\" vga=788 ip=frommedia nosplash live-media-path=/live-hd bootfrom=/dev/sda6 toram=filesystem.squashfs
initrd /live-hd/initrd.img
}

Could you tell me, is it a doable way to restore partition(/dev/sda5) from boot a local disk partition(/dev/sda6)? If it is, is there anything wrong with my boot parameters, or the steps?

Thank you so much!

So if your image was saved to /dev/sda6, in your boot parameters, add this:
ocs_prerun="mount /dev/sda6 /home/partimag/"
then Clonezilla can find the image.
