Kari from tenforums shared a post on how to custom a recovery partition, the guide is very intuitive and practical
I would like to add one more suggestion if you’re using an external hard drive (HDD or SSD) as a secondary disk, that’s to Clone the system as a backup, of course, Windows has no CLONE function, we’ll use a third-party disk managing program instead
Creating a system recovery partition is to prevent system fail when Windows fails to boot, having a backup of personal data is important, but nothing can be accessed when the OS can’t boot, so having data on the backup partition is not enough, having accessible data matters
In Partition Expert, we can clone the entire disk and make the disk bootable, when the original system fails to run, we can use the cloned disk, and since it’s a clone, all personal setting and programs are still there, let’s begin
Firstly, we download this program, install it or not, if you prefer the portable edition, then follow the steps below:
Tips:
Then plug-out the connected disk, it’s bootable now, next time when the original OS fails to boot due to upgrade or blue screen, you can directly boot Windows from the cloned disk
