What is one of the best ways to partition my hard drive? It's 110GB. I will be installing Fedora with XFCE but I want to also install other linux distro on the same laptop to experiment and I want to have the iso on the hard disk and install them from the hard disk. I'm not sure how many distro I will try but I could remove the ones I don't like.

Thanks in advance,
Mike

Why not run the other distro's in a virtual machine?

Kind regards

One partition for each distro + one swap partition + one partition for shared data. Smaller distros will fit into a couple of gigabytes, the larger ones will need more, especially if you start adding software from their repositories (say, 8-12 GB).
I believe the maximum number of partitions / drive is fourteen so minus swap and shared data, you should be able to have twelve distros.
Start by creating an extended partition at a 30-40GB offset from the start of the drive, then use a section of that partition to create the swap and shared data partitions. From there, you can add new OS partitions one at a time, whenever one is needed.

Should the distro and partition for shared data be primary partitions?

it's not needed

* note that you are only able to make 4 primary partitions

Doesn't matter, Linux doesn't care about that.

In a perfect world, I would want a single swap partition, a single /boot partition, a single /home partition, and one root partition for each distro. Whether all distros would be capable of installing kernels and updating the bootloader in a single existing instance of /boot seems a bit optimistic. You might be able to have each distro create its own boot partition in its root filesystem, and then manually merge it into the 'one true /boot' partition.
However, there may be a requirement that the bootloader's bits live in the first 'some-number' of sectors or GBs of the disk, and some distros may dislike creating a /boot directory that is too far away from the boot sector. Or, maybe this a restriction that has gone away with newer systems & software.

Try to Select advanced Partitioning in installing distro and study how to make a partition in your HDD. Dont Select automatic partioning....

it is like install windows 7 or XP sir.

I'd look at a normal install size of my first choice. Say for example it take at least 5G and then guess in for some apps and junk so say 15G or so. Then I only make the first install a partition at about 15G. Leave the rest open. One next install do the same. Make a good guess at the time of install.
