I tried booting from a Pop!OS ISO from the Windows 10 BCD, but it fails and shows "init: line 3: can't open /dev/sr0: No medium found"
I've made the ISO to run from the RAM and the file exists on an NTFS partition. The ISO uses ISOLINUX and to check that i ran "file -s /path/to/ISO" which showed
pop-os_19.04_amd64_nvidia_4.iso: ISO 9660 CD-ROM filesystem data 'Pop_OS 19.04 amd64' (bootable)
so i thought it wasn't intended to be run from USB; so i added isohybrid feature using the latest syslinux-utils and again ran "file -s /path/to/ISO" and it showed
pop-os_19.04_amd64_nvidia_4.iso: ISO 9660 CD-ROM filesystem data (DOS/MBR boot sector) 'Pop_OS 19.04 amd64' (bootable)
but the same error persists
I've even tried booting the ISO on an AIO-boot USB through Grub2 but the same error persists...
I've also made changes to ISOLINUX.CFG to disable loading floppy (as suggested somewhere) but no change
