Once you have a working entry for your favourite distro, chances are you can wholesale reuse them when the next version comes out.

Even though these settings differ between various distributions, the distributions themselves don’t change them very often. You can then copy these parameters to the grub4dos menu.lst. One way to figure out which options to pass to the kernel (and where all files are located) is to first chainload the included bootloader and inspect its boot configuration.

This can require a bit of trial and error, because every distribution seems to have their own convention on where the files for their live images go (in /live or /casper or /boot or …). Re: Confusion strikes: GRUB4DOS appears on USB boot OK no extra help is needed at all for openSUSE the iso is a full HD image and you only need to do a binary copy to the USB device (not not a partition the device. The solution is to not chainload the next bootloader, but have grub4dos directly boot the linux kernel of the ISO. However if you run these images with the inception chain of bootloaders, the references to the various file systems get mixed up and the ISO will fail to boot with “Unable to find a medium containing a live file system”. “Fatter” live images typically ship the filesystem as a compressed image and play a similar trick to give you a working system. The advantage is that you don’t need to know where all files are located inside the ISO image, this is handled by the bootloader of the image itself. Typically this will load the instance of grub shipped with the ISO, which then boots the kernel. What this does is find the ISO, extract it, loopmount it in memory (first three lines) and then use a grub4dos trick by chainloading the bootloader of the image it just extracted. Map -heads=0 -sectors-per-track=0 /images/ubuntu-mini.iso (0xff) You just need to copy the ISO image to the disk and add an entry to /boot/menu.lst that looks roughly like this: title Ubuntu Mini Installer #grub4dos, #iso, #linux, #multiboot, #ubuntuĪ previous post explained how you can make a multiboot stick that can boot ISO files using grub4dos.
