I have an HP laptop and I would like to back up the recovery partitions. There are three reserved partitions, SYSTEM, HP_RECOVERY, and HP_TOOLS. There is an option in Windows to create a recovery media, but this is not what I'm looking for because it would use up a whole USB drive.
I'm trying to back up the necessary recovery partitions, into iso files for example, so I can burn them on a USB/DVD whenever I want to recover the system.
I attempted to back them up by booting from a live Linux then do the following:
cat /dev/sdb3 > /mnt/hd/hp_recovery.iso cat /dev/sdb4 > /mnt/hd/hp_tools.iso
It did back up the partitions, and there seemed to be some boot files like efi/boot etc. however, when I tried to burn the iso into a USB by reversing the above commands the USB failed to boot.
- What is the SYSTEM partition and do I need to back it up?
- Is there any way to make the USB that I burned from iso file bootable?
- If not, is there any other way to back the recovery partitions up without dedicating a whole USB drive for this purpose?
