USB boot disabled

HP Recommended

I cannot boot anymore into the Acronis Rescue Media, which was created as part of their Survival Kit on an external hard drive. I created another USB with Simple Option, but it does not work as well. One of the changes that I did inbetween is that I inserted an empty M.2. SSD along with the SATA SSD, 2.5``.


My parameters:

  • HP ProBook 440 G4
  • Win 10x64, build 1909
  • BIOS P85 Ver. 01.34
  • Acronis True Image 2020

It looks like the boot from the USB in UEFI mode is disabled (the same for both USB).

Here are the screenshots from the BIOS. 

Boot options:

It seems to be a similar issue as this one. In the solution they write clearing the CMOS. What is CMOS and how to clear it? Is ti safe?

The solution was as simple as when you are in boot options and selected the usb you may enable/disable the boot (on HP by pressing F5). I wonder why it disabled by its own. The only thing could be that I inserted a new M.2 SSD. P.S. Please close the issue.
