Windows 10 - Burning system recovery disk on other pc

Hello

I updated my laptop this weekend from Windows 7 to Windows 10 (Home). Everything seems to run fluently and I already made a back-up on a secondary internal HDD (for both the system and the files). I will copy those files to an external HDD to make sure I keep those copies.

After I made the system back-up, Windows asked to create a "system recovery disk", which I temporarily ignored because I'm having a problem with this. My laptop does not support "USB boot" (I figured this out while updating to Windows 10) and he can't write DVD's too... It has a CD/DVD driver, lucky enough, so there still might be some options to create a "Windows 10 disk".

Is there a way to create the files for a "system recovery disk" of my laptop (I also wonder how big that file would be?), copy those files to an external HDD afterwards (with plenty of other stuff on, so I don't want it to erase everything!), take that external HDD to another PC and burn it on a DVD there? If so, is there some very trustable program to do this and some manual to follow?

The most reliable way to support your installation is not to use the built-in deprecated features for backup.

Again and again tenforums members recommend the routine use of disk imaging e.g. Macrium reflect (free/paid) + large enough external disk.

Windows- all partitions created when installed- can be imaged with 1 button selection, as can any other disks or partitions.

It is exceedingly well supported and documented, youtube videos, a couple of simple tutorials here, etc.

You chould not rely on internal disks for your sole backup. Ok for travelling perhaps. Your backup disk should be capable of being removed, powered down and stored securely. Think fire/theft/flood/viruses/ransomware.
