(7) A nested Grub menu system is showed (Showned in Post #32 to #34. (I believe this has not been tried before) (6) The 145-system booting menu can be created ahead of the installation of the systems. (using the exactly the method every Linux boots a Windows but on all other systems)

(5) Every system is booted identically and universally by the same 3 lines of commands. (4) 3 Dos, 5 Windows, 137 Linux (more Linux since added plus one Solaris and 2 BSD) using 3 Pata and 2 Sata hard disks) (The number is limited by the availability of partitions/hard disks) Grub can be attached to any OS, even in ntfs partition as work around available). (3) The controlling boot loader is not attached to any operating system (This is my own choice. (indirectly becasue every system has its own original boot loader preserved) (2) One standard Linux boot loader controls all the systems. (Let me know if there is anything simpler or easier) (1) A simple howto procedure, which is applicable from 1 to 300+ systems, is described. For this reason I summarize the information briefly as follow:. Updated 20 Sep 07, a new nested Grub menu system + added Solaris and BSD systems showned in Post #32, #33 and #34 -Īuthor's notes - This thread has picked up some interest from the Internet by readers who commented the title without reading its content. Updated 17 Sep 07, A warning added in Post #21 on 63 partitions in a Pata hard disk is no longer supported by Linux kernel newer than 2.6.20. The new kernel 2.6.28 is not universally available in every Linux and many teething troubles will have to overcome before a user can install a large number of operating systems into a hard disk but it is coming this way. I have managed to run a Ubuntu from sda130! Currently I am trying a 1.5 TB hard disk with 60 partitions and will report the progress later.

Updated 8 Apr 09, Good news! kernel 2.6.28 and newer have finally decided to support large partitions.

No good for the 32-bit MS Windows but alright for Linux with Grub2. Updated 4 Jun 10 - The gpt partitioning scheme can have 128 partitions inside.
