Grub2Win and Acronis 2019 (Windows PE) booting from a partition
I'm writing this as I spent the last few hours getting this to work, but I finally did. It would be nice if Acronis would have the ability to create a rescue partition which I could simply run using EFI, but as they do not I had to hack my way around it, this is what I figured out finally.
Steps:
You need a partiton about (3Gb or larger, I wanted one big enough for a recovery image as well).
Format said partition as NFS and mount it using any drive letter (say I: for this example)
Next download grub2win from Sourceforge and install to this drive
Reboot you should have a boot menu with Windows as an option, if not you may need to adjust bios to boot to grub2win.
Use grub2win to boot to Windows 10
Install Acronis 2018 and create a Windows PE rescue ISO image
Mount said image and copy teh contenst to you partition (above i:)
Now start grub2win and add a new option:
Type: other name: Acronis 2019 Windows PE Recovery
Fill in the following:
if [ $grub2win_bootmode = EFI ]; then
set root=(hd0,gpt5)
set USB_drv=/bootmgr.efi
set USB_efibootmgr=/EFI/Boot/bootx64.efi
getbootpartition file $USB_drv
if [ $reviewpause -gt 0 ] ; then
echo Grub will now boot Windows PE Recovery drive
echo Recovery disk address is $root
echo EFI DRV address is: $USB_drv
echo EFI Boot MGR address is $USB_efibootmgr
sleep -v -i $reviewpause
set reviewpause=0
fi
chainloader $USB_efibootmgr
fi
Now my partiton was #5 on teh first drive you can use diskpart (cmd -> diskpart):
list disks
select disk 0
list partitions
exit
Change the hd0,gpt5 to the partition ID.
Save the changes select an Icon Apply and Applay agin
Now reboot and select your new boot option it should boot into Windows PE with Acronis 2019.
Finally reboot into Windows proper and unmount your partition (to be safe).
Hope this helps other people,
ERIC
