ESET SysRescue Boot Error: "Unable to find a medium containing a live file system"

[Guest 0]

Created bootable ESET SysRescue flash-drive using Rufus 4.0 (portable). Booting a computer from it gave me an error message: "Unable to find a medium containing a live file system" (white text on black screen).

Solution: Turn OFF Secure Boot in BIOS/UEFI

I hope this helps.
