Brief background:
Just downloaded EasyBCD, in process of getting 2nd Laptop for boot experiments but bit new to Boot Options world. Only things actually done in past is create Win10 install USB with ISO and Media tool (used Rufus once also) and created a 3rd party Image backup Emergency Boot USBs with Rufus.
If understand correctly one can create a bootable image (with various softwares) onto physical disk device (HD Partition, DVD, USB etc) and then in bios or UEFI set aforesaid to boot on next start. I understand the term bootable requires a bootstrap and bootloader and sometimes of a specific (first) record format (i.e. UEFI wants FAT32)
Also apparently one can also native boot (MS Windows Specific) a VHD file.
Question:
But is it possible (without copying it first to a physical primary partition, HD, USB etc) to Mount a bootable IMG OR ISO file and then set the system to boot from this file?
In other words I'm wondering how Bios or UEFI will (on boot) even knows about mounted files?
