Hi, I have followed @george1421’s excellent guide to setup booting a Ubuntu 20.03 image which is working, but for some reason it’s not booting to Live CD. When booting the VM it goes straight to the install on disk procedure. I did google around but most of the links relate to older versions with a different netboot (vmlinux instead of linux), I’ve added the boot=live argument as per below which doesn’t seem to do anything, anyone know the answer to this?

kernel tftp://${fog-ip}/os/ubuntu/live20.04/linux
initrd tftp://${fog-ip}/os/ubuntu/live20.04/initrd.gz
imgargs linux boot=live root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:/images/os/ubuntu/live20.04/ locale=en_US.UTF-8 keyboard-configuration/layoutcode=us quiet splash ip=dhcp rw
boot || goto MENU

Many thanks for any help,
Will

@Sebastian-Roth I’ll do that now bud and report back when tested.

@george1421 I think I follow, I’ll give it a bash and let you know, thank you :).

@george1421 So in theory all I need to do is copy those files from a ubuntu install to the tftp folder on the fog host?

@Sebastian-Roth Yes when I was googling around attempting to figure out the issue I came across the vmlinuz boot a lot but assumed it was part of older distros as couldn’t find any newish posts. I think you’re on to something here too.

@george1421 live mode being the live CD options the ubuntu installer gives you when for instance you burn to CD or mount on a USB and boot it. so basically running it in RAM. Through fog currently that menu where you can ‘try ubuntu’ is not available, I guess some boot param makes it skip straight to ‘install to disk’ mode.

As far as I understand it, netboot is running an OS over the network but the storage isn’t local but the OS is still technically installed somewhere else so not related to to this unless I’ve got that wrong?

You say it should boot to installer mode right away, if this is expected how do we pass an argument to enable the menu where you can ‘try ubuntu’?

I don’t know a lot about this stuff so I’m just using this as a practical end-user and I’ve followed the guides to get this up and running, unfortunately, troubleshooting this albeit small issue is well out of my area of understanding, I don’t know how any of this works under the top layer so I can’t help much but I think other people will run in to the same thing as I have as I’ve not done anything bespoke (I wouldn’t know how to :)). I can however load more VM’s/run some tests/arguments if any more ideas, let me know.

boots straight to Desktop mode

You meant install mode I suppose?!

Yep install mode

@Sebastian-Roth Didn’t get round to this last night but just tried Ubuntu 18.04 and same problem, tried both suggested boot arguments boot=live and boot=casper, boots straight to Desktop mode, pictures below:

Thanks @Sebastian-Roth but this also boots to desktop install, I think it may be something to do with netboot files from googling, does this perhaps specify a desktop boot only?

Perfect @george1421! I’ll give it a whirl, thank you.
