USB drive suitability for Macrium Reflect Rescue media

Windows 10 ver. 1903

I want to make a rescue disk/bootable media in order to restore a Macrium Reflect disk image if disaster ever strikes.

I have:

1. A usb thumbdrive with various folders and files. I'm not sure it's bootable. I don't want to lose the contents.

2. An external usb SSD with several folders and the Macrium image of my C: drive. Not sure it's bootable.

3. A usb thumb drive that is bootable, but has the installation files (ISO?) that I used to install Windows 10 on my new PC.

Are any of the 3 suitable for making a rescue source so that I could reinstall my saved image to an SSD if something happened to my system?

I have placed a Macrium Windows boot option on the boot menu

Thank you wanna.

Do I need to format or otherwise prepare an new USB stick in order to make it bootable and to place the files for Macrium rescue?

If I recall, Macrium will do what needs to be done when you make the recovery stick within Macrium. I think it will be FAT32.

But that's not enough.

Either it boots your PC to the Macrium interface-------or it doesn't. Regardless of what you do to it, you need to find out if it will boot by testing it using your boot menu.

You should download Macrium's user manual. It's a 500 page PDF.

Will do. Thank you.
