145 Operation Systems; ONE PC...No Virtualization

When you read the title of this blog entry you were probably thinking virtualization, but the individual actually did this by creating partitions for each operating systems: 3 DOS, 5 Windows, and 137 Linux. Here's a brief summary:


"(1) A simple howto procedure, which is applicable from 1 to 300+ systems, is described. (Let me know if there is anything simpler or easier)
(2) One standard Linux boot loader controls all the systems. (indirectly becasue every system has its own original boot loader preserved)
(3) The controlling boot loader is not attached to any operating system (This is my own choice. Grub can be attached to any OS, even in ntfs partition as work around available).
(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)
(5) Every system is booted identically and universally by the same 3 lines of commands. No need to worry what OS it is. (using the exactly the method every Linux boots a Windows but on all other systems)
(6) The 145-system booting menu can be created ahead of the installation of the systems. (I believe this has not been tried before)
(7) A nested Grub menu system is showed (Showned in Post #32 to #34. This probably has not been tried before)


Although not indicated by the thread these points should be obvious to experienced PC users


(a) The described procedure is applicable to any boot loader. (Grub happens to be the easiest while the others may have various limitations or take too long or too much work to achieve the similar goal).
(b) Everything is standard, no new thing invented, no hacking involved and the technology has been there all the time (Anyone can do it. I am just the one who is willing to write about it)
(c) The arrangement makes every system suitable for booting manually, say by a Grub floppy or booted by any other boot loader(Every system is self sufficient with its own boot loader inside the boot sector of the residing partition)"
