Hello:
It will be a little bit long to explain what I want to do.
I have several linux OS-es on a hard disk. Each OS has its own boot loader installed on the OS's root partitition. The MBR has also a boot loader. This boot loader chainloads the other boot loaders on the root partitions. This makes easy to completely separate different boot menus for different OS-es.
Me too.
For the management of the above scenario at least one of the OS-es must have 2 different boot loader install configurations, one for the mbr boot loader (chainloader) and one for the OS's own boot loader on the root partition.
I don't do that.
ps: Please don't ask me why I do want to do this and please do not suggest that I use one GRUB2 menu to load all of the different OS-es. I want to do it because I could do it with legacy GRUB and I expect that it is doable with the advanced GRUB2 too, and anyway I got used to do it that way. Thanks.
Then I will not say how I do it :-) -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
