Please i need a Redhat O.S, want to install in my system. I want to partitioning my hard drive(Window and Redhat Linux).

You haven't actually asked a question. But if you want to buy RedHat Enterprise Linux, you can do so directly from RedHat's on-line store:

https://www.redhat.com/apps/store/desktop/

Or you can get CentOS, which is more or less a free version of RedHat. Use the Search option of these forums to find out about dual-booting.

http://www.centos.org/

Why Redhat (as opposed to some other Linux distribution)?

I will guess that you do not intend to pay for Redhat. If that guess is incorrect, that would make the rest of what I am about to say irrelevant.

You probably don't really want Redhat.

If you selected Redhat just because you heard it was a good Linux distribution (or any other non specific reason) you probably should get a beginner friendly Linux distribution, such as Ubuntu.

Since you want to partition with Windows, I expect you want a desktop distribution of Linux, rather than a server distribution. But if you do want a server distribution, then there are good reasons to select one in the Redhat family. RHEL (Redhat Enterprise Linux) is the best basic design for a server distribution. Centos is the free version of RHEL. If you find a "free trial" version of RHEL, don't get it! "Free trial" RHEL is only useful for finding out whether it is a good idea to pay for RHEL. If you don't intend to pay regardless of results "free trial" RHEL is a dead end. Start with Centos (just like RHEL except for branding and support). You can use and upgrade Centos as long as you like without ever paying for support. Very good Centos support is available free here at LQ (provided by unpaid volunteers).

If you want a desktop distribution of Linux, do you have some specific reason to want one in the Redhat family? If you have such a reason, get Fedora. But if you don't have a good reason to select the Redhat family over the Debian family, get Ubuntu.

There are lots of other distributions you might choose. My advice to select one of Ubuntu, Centos or Fedora based on a couple simple aspects of your requirements is very sound advice. But it is far from the full set of reasonable choices. If you look to a wider range of choices, I think you are more likely to get lost than to find a better choice. But others here may have very different advice. However, if your plan is to get Redhat without paying for it (by free trial or other means) I think all the competent advice you will get will agree not to do so.

Thank you all 4 d contributions.Actually what i want is to install a Linux O.S on my system,co's i start reading Linux Book(Redhat book) i want have d O.S on my system in order to be practicing it,at the same time i ask Redhat co's i want to build my career on that aspects.But i will be grateful if you can help me with any useful advice.Thank you

Without seeing the book, it would be hard to guess whether it would be a better fit for Centos or for Fedora. Unless you really prefer paper books to online, having a specific book is not a great basis for choosing a Linux distribution. There is plenty of online documentation available free.

For the career aspects of learning Linux, Centos is the clear best choice. But Centos is harder to install and harder to learn to use than Ubuntu. If you are likely to give up after the process starts out difficult, you would be better off learning the basics of Linux with a beginner friendly distribution (Ubuntu) and switching to Centos later. There is a small amount of unlearning/relearning involved in switching from a Debian based distribution to Redhat based, but most of the Linux learning will be in common between the two. Also, many jobs in Linux IT would expect you to understand the differences between Debian based and Redhat based Linux.

Here's the book i am currently reading:The Linux® Command Line by William E. Shotts, Jr. but i want in the near feature to have RHCE Certificate.Thank once again

Please spell out your words. English might not be your first language, but that's no excuse to use Twitter-style shortcuts that save you .0001 seconds and make it harder for everybody else to read.

In that case you should probably use CentOS, unless you plan to pay for RHEL.

Please is this software a Linux Operating system: ISO 1 shrike-i386-disc1.is

Yes, and it's also 9 years old and incredibly obsolete. Why are you looking into an old old old RH9 distro?

Actually i just want to start practicing the Linux Commands with real Linux Operating System on my Laptop.I am going to attend a Certificate Course on Linux Administration at India by October Ending,But i want to have as much knowledge as i can before then.Thank you all

So install CentOS. If you have enough RAM you can just install it in a VM without having to repartition the drive.

Please can you help me with CentOS and the procedure to install it on my system.Thanks

Are you planning to dual boot or install it in a VM?

I have 4.0 GB RAM on my laptop with the Hard disk of 500GB,So i don't actually know which one is better to the dual boot(Partition) or install it in a VM.Thou i don't have Virtual Machine on my laptop,but i will be happy if you can help me with any one among the two.Thanks
