I guess I don't understand why you need 60+ distros. They are all basically the same. Just pick one in the Distrowatch Top 10 and spend a year with it.

If it is cosmetics you're concerned with, a quick trip to will fix that.

Prior to the hard disk being detected by libata a Linux kernel can have a maximum of 256 block devices coming from either 4 IDE disks each can have 63 partitions or 16 Sata disks each with 15 partitions. The whole and the partitions make up 64 and 16 devices in IDE and Sata disk respectively. Modern kernels have dropped the limit because a dynamic method is now employed in detecting partitions.

Partitions in a hard disk can be used for Dos, MS Windows, BSD, Solaris and other PC operating systems too.

People can be interested in large number of partitions other than just running the operating systems. For example the capability of a boot loader can only be exhausted by booting a large number of partitions and at the high positions of the hard disk.

A way to play with many distros

Hi Saikee
I have read (and reread) your
"145"postings and have a couple of questions.
You say you put the bootloader in its own partition and format it for FAT 16.(or32)
Later, in a subsequent post you say that you put your personal data (photos, music, etc.) in a data only partition.
This is not the same partition in which you put the boot loader?

How big is the partition used for the boot loader?
I have just got a new hdd and a friend has installed Win7 to the first partition (100gig) of a 1 terabyte hdd. (leaving about 850 gig unallocated)
I have been using K/Ubuntu for a few years but am still very much a newbie.
What changes have to be made to the Win bootloader to allow me to install (by chain-loader) some linux distros?
If you have addressed this (in detail!) please point me to your tutorial
Many thanks for all the information that you have offered to the linux community

I am not aware of Win7 can be booted by a floppy but Xp can do that.

As far as Grub is concerned both Grub1 and Grub2 can be accommodated inside a floppy!

Grub can be placed in any partition. It only needs access to the boot sector of that partition.

I put my personal data in a data-only partition so that it is accessible to to operating systems. Grub can be placed inside. However it is wise to put as many boot loaders in a partition for just the boot loaders as they are supposed to be able to co-exist with each other!

I certainly have the boot loader for Dos, NTLDR (that boots Win2k and Xp), bootmgr (that boots Vista and Win7) and Grub sitting side my side in a Dos partition for booting the 50+ operating system in one hard disk in one of the box. It is easier to maintain.

Grub2 can read a NTFS partition so one can house Grub2 inside any MS Windows to boot Windows as well as Linux. This is achievable using the standard "grub-instal" command in Linux that has Grub2.

There are many tutorials for using Win7's bootmgr to boot Linux. The key steps are included in the Just booting tips of my signature but a more detailed write up is here.

I have tried using bootmgr to boot 150 Linux before by write a batch file (script in Linux). I would say Grub is between 2/3 to 1/2 less work.

bootmgr only chainloads a Linux.

As a rule any boot loader can chainload an operating system as long as that system has a boot loader residing inside its partition. In chain loading you just use one boot loader to boot another boot loader. It is always the second boot loader that fires up its own master. That is nothing to it.
