Any pre-built boot ISO from 2017 for Acronis will require rebuilding to work with a UEFI-only system like this one.  It won't support UEFI boot. If you're trying to restore an image made by an older version of Acronis, you can try a boot ISO for the newest version (it's called Acronis Cyber Protect now, not True Image) -- if you're trying to back up the system from a flash boot, consider Macrium Reflect, which can build a native WinPE flash drive that will be UEFI bootable.  Macrium Reflect is much easier to use, and is free for home/non-commercial use.  
I created a Flash drive with an 'ISO' file in there for an alternate boot.  I press F12 on power up to select the boot drive. The Bios comes up to select the drive.  But it does not look like past computers I have had.  Here is a photo of all the options I have.... I have moved the given choices around to various positions, but the Flash drive will not be recognized and boot up. What am I doing wrong? Ed   [IMAGE]
Can not change bios to boot from flash drive
