What is your operating system?
If you are on Windows, you must use a third party CD burning application like Nero.

Edit:

After reading your other thread (http://www.linuxquestions.org/questi...rprise-814660/), I can confirm you are on Windows.
Tip: Only open one thread with all the information inside. It is easier for us to help you that way.
I can see you have already burnt the CDs.
AFAIK, Anaconda will ask you if you want to wipe the partition for installing. There is no need to "uninstall" your previous install. Just wipe it.

Anyway, BACK UP YOUR IMPORTANT DATA BEFORE WIPING ANYTHING.

Wiping = erasing the partition = sort of uninstalling.
In Anaconda, when it asks if you want to format the partition, say 'yes'. This will erase your old system and all information on that partition. Be very careful not to erase the wrong partition. You want to erase the partition with the old red hat and not the Windows one. BACKUP YOUR IMPORTANT DATA BEFORE ERASING ANYTHING.
Uninstalling is not the right term. You don't need to uninstall. Uninstalling is for programs. It is like in your car. If you want to change the tires, you have to uninstall the old one before putting the new ones. If you want to change the whole car, you just throw the old one away and get a new one but you don't uninstall the old car, that makes no sense.

Are you planning to pay for and register this copy of RedHat?

If not, you're making a mistake. I'm not talking about the moral or legal issues, just the practical issues. You probably should start over with Centos. In every way, Centos is either as good or much better than an unregistered copy of RHEL. Expressed simply: Centos is the same software as RedHat, but access to the repositories to add packages or update Centos is free, while access to RedHat repositories requires registering.

That sounds like you're asking how to make a bootable CD from a .iso file. But your other thread started slightly before this one implied you are past that. Which is it? Are you trying to make a bootable CD? Or are you trying to use the bootable CD to install a bootable copy of Linux on your hard drive?

You should be clearer about what you want to accomplish. I expect you want to discard your previous install of Linux and keep your previous install of Windows and end up with a dual boot of Linux and Windows. If that is not correct, please clarify.

If it is correct, that might be another mistake. I expect you didn't accomplish much with your previous install of Linux before deciding it was "corrupted". That may be because of a poor choice of distribution.

RHEL dual boot with Windows is not a good choice for most people who try it. It is possible to set up correctly, and it is a good choice for some people. But in most cases it represents a very bad choice of distribution.

Even Centos is probably a bad choice.

I'm making some unsupported guesses about your needs (because you haven't said anything about how you intend to use the computer). But my guess is that for a dual boot with Windows you would be much happier with Mepis 8.0 or with some version of Kubuntu or even Ubuntu.

Part of my own dislike of Mepis 8.5 is because I follow the general rule "when all else fails read the manual". Earlier versions of Mepis were much more usable without reading the manual than 8.5. The Mepis 8.5 manual is quite good (compared to the documentation of other Linux distributions). If you read the manual before all else fails, you might like Mepis 8.5. But I still prefer ealier versions.

@AGROUF : thanks once again for your support. but how will I know which partition to wipe . by mistake can the windows partition be wiped out? That would
very troubling then. but I would surely backup my data.

@JOHNSFINE:thanks for your support and sorry for not being very clear in my threads. I have downloaded all 5 ISO images . Now I ve read that another method to work with linux(for begginers like me) is to use a bootable CD rather than
installing it in the hard disk. It is this bootable CD which I want to make.I read something like Loopmount boot.iso image.

Downloaded the files, but not burned the images to actual CD's?

That is called a "liveCD". Most Linux distribution install CD's are also liveCDs. But I'm not sure about RedHat.

I think I read somewhere that you can press some key during the isolinux portion of the RedHat CD boot and get some menu from which there is a "recover mode" choice that is actually a liveCD environment (I'm sure I have details wrong even if the concept is right).

I have never tried to use a RedHat or Centos install CD that way. Centos has a CD that was designed for liveCD use (rather than being an install CD that can also do liveCD mode). I've tried that one. It understood some obscure hardware that other liveCDs didn't, but generally was harder to use than other distribution liveCDs. Other Linux distributions are much friendlier as liveCDs.

liveCD mode is helpful to discover if you have driver issues with your display card before doing a full install. It is very helpful for repairing existing Windows and Linux installs. It can be used to learn Linux without installing if you really really can't afford the hard disk space to install.

But liveCD is not a good mode for learning Linux. Many actions will cause your process or even the whole the system to lock up for many seconds at time while something designed to be read in a fraction of a second from the hard drive is read hundreds of times slower from CD. A beginner will frequently wonder whether what he just did was wrong, causing it to not do what was desired and meaning waiting longer won't help vs. the CD is slow and the desired effect will occur many seconds later.

I think that is yet another approach, using the .iso file for a bootable CD without ever burning the image to a CD. I've read about it but didn't understand all the details and never tried it.

RHEL (& Centos) are avail as 1 DVD or a set of CDs. Bith are installable by booting the DVD or 1st CD in the set.
A live CD is a different thing; basically you just run from the CD without installing onto the HDD. Good for checking out a distro without installing.
For RHEL you pay for support & updates; Centos the updates are free, but no support. Your choice.
