Booting Hello iso from grub2 #420

Closed knedlyk closed 1 year ago

knedlyk commented 1 year ago

I tried different ways with no luck to boot hello ISO from grub2 in order to try the system on laptop. One of the variants is below:

menuentry "FreeBSD iso" {
    insmod part_gpt
    insmod search_fs_uuid
    insmod chain
    insmod fat
    insmod part_gpt
    set isofile="/images/hello-0.7.0_0G160-FreeBSD-13.0-amd64.iso"
    loopback loop (hd0,gpt4)$isofile
#    kfreebsd (loop)/boot/kernel/kernel.gz
#    kfreebsd_module (loop)/boot/mfsroot.gz type=mfs_root
#    kfreebsd (loop)/boot/loader
    chainloader (loop)/boot/loader.efi
}

Is any chance to do it properly?

Hello @knedlyk. I don't think that it is currently possible to do that with Grub alone, but it is possibly with Ventoy, which I think is a modified Grub.

Ventoy has different way to emulate iso and then boot system. Is it possible to add "grub mode" to iso? Might it help?

That Ventoy "grub mode" is for ISOs that have issues being booted by Ventoy. There should not be issues with booting helloSystem using Ventoy. helloSystem itself is using the FreeBSD bootloader. So we don't use grub. If you'd just like to try out helloSystem, you can write the ISO directly to a USB stick and boot from there. That's the easiest way. No messing around with bootloaders at all.
