I don't have this model or series to test out. Did you try DVD as well? I find HP iffy at times and have to fall back on DVD boots.
Hello everyone, my HP 840 g2 laptop won’t boot any bootable USB flash drives, this problem occurred 1 month ago, I have a Samsung SSD installed and I’m sure it’s not a bad drive issue because I tried another SSD and it still WONT boot my windows 10 bootable, I just want to reinstall windows with this bootable USB, I also ran all hardware diag test and they all PASSED!, and I’m sure it’s not the bootable, I already installed windows on another computer with it and reinstalled windows with in the bootable just to make sure, I used the Rufus tool to create the bootable as well . Some input would greatly be appreciated thank you
