Is it possible to boot a generic OS (not necessarily linux or windows) from USB by simply loading a live-CD image file? Use case: one USB drive with custom MBR

Is it possible to boot a generic OS (not necessarily linux or windows) from USB by simply loading a live-CD image file?
Use case: one USB drive with custom MBR, one text configuration file and one or more liveCD images. On boot-up, the user selects one of the images and loads that generic OS.
- vasi 16y agoThis isn't possible in the generic case. Once the OS loads, its kernel will look for a root filesystem somewhere, and the ISO isn't one of the usual places it will look (ie: a partition).

DOS (MS-DOS, FreeDOS, DR-DOS, ...), Windows 95/98/ME and boot loaders (Syslinux, grub, grub4dos, gujin, gag, mbldr, ...) boots, other operating systems must be aware of the memory mapping. With SuperGrub2Disk http://www.supergrubdisk.org/wiki/SuperGRUB2Disk http://www.supergrubdisk.org/wiki/SuperGRUB2Disk you just have to add a iso file into a specific folder and it will automatically be added to the bootloader menu. But AFAIK it does currently not support the memdisk solution.
