I have successfully created a backup image of my laptop's hard drive using CloneZilla. Before making system changes I want to verify that the backup is fully restorable and can be booted from.
I have successfully restored the image to an external USB drive and tried booting from that, however it always seems to load the copy of windows 8.1 from the local disk (to check, I made a simple change to the desktop background after the backup operation). I have tried disabling the boot option in the BIOS for the local disk but I suspect it is reading the
MBR GPT boot information from the external drive, then using that information to load the file system on the local disk (please correct that assumption if it's wrong) There is no option in the BIOS to disable the local disk entirely.
I then tried booting from the external disk on an isolated PC and I get a blinking cursor (HAL/Driver problem?)
I've also tried using VirtualBox to boot from the USB device using both;
- a restore of the backup image
- and a disk-to-disk clone
Both of these result in a "no bootable medium found" message from VirtualBox.
Clearly I don't want to perform an actual restore to the local disk, in case the backup isn't fully functional.
How can I test that the CloneZilla backup I've created is recoverable in a safe environment?
Starting afresh, I recovered the backup image to the external drive again. When plugging it in Disk Manager reports an error
The disk is offline because it has a signature collision with another disk that is online
Here's what it looks like when the disk is brought online.
I wonder if the "Bring Online" operation is causing partition flags to be lost? If that's not the case then shouldn't CloneZilla be replicating these attributes as part of the backup?
