Thanks very much. I suspected that but it looks like I don't have to make a duel-boot system afterall. Someone on the debian list suggested I use a chroot jail to encapsulate the old distribution which, in this case, should solve the problem I was trying to solve in the first place.
If it doesn't turn out to work, I still have all the pieces so it is worth the try. john doe <johndoe65...@mail.com> writes: > > According to (1) you are out of luck. > > To be able to fully controle the boot sequence I would install eatch > distro in a VM. > > Granted, you would still have the issue of not being able to access grub > on where the VM are installed but that would eliminate playing with grub > "blindly". > > See (2) for serial console. > > 1) https://lwn.net/Articles/302159/ > 2) > https://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/configure-boot-loader-grub.html > > > -- > John Doe > >
