Hi..
Let me show some basic steps which will help you to install RHEL through server or Network

Before we start, i would like to point out some informations

• Steps shown here are explained with RHEL 5. But the procedure is same for all versions of RHEL which supports Network installation
  
  
• For the Convenience to take snapshots, i'm installing RHEL on a VMware (Virtual Machine). So to me, some hardware resources are limited like physical memory, hard disk space, Graphics adapter ..etc
  
  
• My Server which contains RHEL images is " LinuxServer " and its address is 192.168.75.100
  
  
• Location of RHEL5 Installation Image on this server is: /home/nightflare/Test/RH5/i386
  Shared folder is: RH5/i386
  So if we want to access this folder through network, then the address would be : 192.168.75.100/RH5/i386
  
  
• Due to limited hardware resources of my machine, i would proceed with TEXT MODE installation which is no different than the Graphical Mode.
  

So lets start.

I have a bootable CD of RHEL which i will need to start with. You can use any live CD or DVD of RH ( which support network installation ) to start the system. I inserted the Disc and set system to boot with it.

1. START THE SYSTEM TO BOOT FROM THE LIVE MEDIUM
If you successfully able to boot from the live CD / DVD, you probably will get a screen like this


Type next to the boot: linux askmethod text and press

The option "askmethod" will set the installer (anaconda installer is default installer for RedHat) to ask us for which installing method should be used. RedHat Linux supports many installing methods like

• CD or DVD (Local CD / DVD are supported. If you want to use Remote CD/DVD, you will have to mount it in a shared folder and proceed with network installation method)
  
  
• Hard Drive (installation files stored)
  
  
• NFS Image (images stored in Network Filesystem Partition over a network)
  
  
• FTP (Installation files stored on FTP Server)
  
  
• HTTP (Installation Files stored on HTTP Server)

The option '" text " will tell installer to use TEXT MODE installation. If you prefer Graphical Mode installation, you can skip this option.

After pressing Enter Key, the anaconda installer will load necessary files and drivers to memory and start the second level of installer. You will see,



2. SELECT LANGUAGE AND SET LOCATION BASED PREFERENCE
After essential drivers and files are loaded, installer will ask for installation language, keyboard etc.


I select English as my installer's Language


On this screen, Choose the layout of your keyboard. In Most cases, The Keyboard Layout is USA, so is mine. But if your layout is different, choose appropriate Keyboard Layout.
I Choose US

3. SELECT INSTALLATION METHOD
Since we start the installer with askmethod , installer will ask for the method of installation.


I chose HTTP, since my RedHat Server is HTTP server.

4. CONFIGURE NETWORK
When we chose Network Based Installation, Installer will prompt for configuring the network.


On this screen, Select what all IP technologies we want to be supported by the installer.


After selecting the IP configurations on previous screen, the installer will look up and resolve IP addresses.


After resolving IP Addresses, Installer will ask you for location of installation files on the network
Since we selected Installation over HTTP , we need to specify the server (Host name of server) which contains the binaries or installation files. And we needed to specify the location of the installation files in the server. Remember this location is relative to server and web accessible directory
ex.: in my case Server Hose name is LinuxServer and IP of server is 192.168.75.100.
Installation image is located under /home/nightflare/Test/RH5/i386
But the location should specify on this screen is /RH5/i386 NOT /home/nightflare/Test/RH5/i386 or 192.168.75.100/home/nightflare/Test/RH5/i386



After entering the details necessary to find the installation images, it will try to get those files.
If everything went fine, then it will try to pull the files from server.


If you see this screen, you can relax. System successfully found the installation files on server and retrieves it.


5. SET INSTALLATION


Rest of Installation is just same as Installation by Local CD/DVD


Just Skip this window. RHEL also comes in CDs which spans over many CDs each with a installation no. like DISC 1, DISC 2 ... etc. This is not our case, so we can skip it safely.


This screen ask to confirm our option to Skip. Choose Skip


Searches our system for any previous installations of RedHat


If Any previous installations were found, installer will ask for whether to Upgrade the previous installation or we need to Reinstall. I choose to reinstall


On next screen, we are requested to specify the partitioning. We can either accept the Proposed Partitioning or proceed with Custom Partitioning.
I Choose Custom Partitioning as it will provide more control over how the spaces are alloted ..etc.


Since I go with Custom Partitioning, I can edit, create and even modify partitions according to my needs.
Remember, I'm working on a VMware. In real cases you may dealing with larger disks or able to set up LVM or RAIDs


Select Whether Need a Boot Loader or not


On This screen, we can choose have extra boot options or not. Booting options are like typing single will cause kernel to log in to single user mode rather than multiuser mode

I would recommend a basic ping command to 127.0.0.1 in the terminal to make sure your card is working. If so, and you know your network is set up correctly check your hardware status in the control panel. Is it set up correctly or is it using another device ie the wired network card while you are "using " wireless.

Hello
A free software operating system based on Linux was created and it was named Ubuntu. It offers all services needed by ISPs, mail servers, DNS servers, FTP servers, MySQL servers, POP3/POP3s/IMAP/IMAPs, Quota, and Firewalls. Red hat, Apache and Ubuntu are Linux software distributors. Ubuntu is widely used because it is free and you don't have to pay any licensing fee. Updates are also available for free and accessible online.
To install Ubuntu Linux software you can use the program "Wubi."
The first thing to do is to download Wubi to your desktop and then run the executable program. Then choose the drive in your computer where you want your installation to go. Wubi will place a file on your local drive. It will use this drive as a virtual hard drive. Most often the C drive is used for this purpose. Choose a bigger installation size to allow installation of other programs and storage of data. Choose your language. Type in your username and then your password for security reasons and for your installation to proceed. You will use this for logging on to your computer, installing programs and making changes to the system. Once you click "Install" Wubi will start to download the installation files. When the installation files have completely been downloaded, you have to reboot. Restart your computer. You'll see on your screen a prompt that asks you to select the operating system that you like-whether you like to boot Ubuntu or Windows. Choose Ubuntu. This will complete the installation of your Ubuntu Linux OS. Another way of installing the Ubuntu Linux software is by using:
An Ubuntu CD installer An Internet connection Everything you need to install Linux comes in one CD that provides a complete working environment. You can get the additional software you will need online for your installation. The available graphical installer makes installation easy and quick. Your computer will have Internet, drawing and graphics applications, and games after Linux has been installed.
Now your computer is ready to work to the max. You'll have it functioning the way you want it and enjoy its features as well. Working on a computer is as much fun as it is functional. You can now browse for information you need, play a variety of games and even listen to your favorite music and watch some videos.
Hope this helps, if so do rate the solution

Redhat ... all installation guides are almost same, but before setting up installation make sure you have no critical data on you drive. You might end up setting it up on wrong drive or complete partition leaving you with erased data.

No worry, if new system or virtua lsystem

Get the drivers for your WiFi card for the correct edition of your RedHat. Wireless card may be incompatable with red hat.

If you go here, the bottom choice in the PLATFORM drop-down box is 64 bit. There are eleven different 64 bit flavors linked from there.

But the 32 bit Linux kernel can be recompiled to recognize up to 64 Gb of RAM. Please post again if you have more questions, and please rate my solution.

try spybot s&d, is a good soft for that job, or try to put ur avast to scan before ur os start. but if ur system32 files ar infected is bad.

There's a couple of reasons that could give this message. The primary is simply hard drive failure and it need replacement. If it's an ssd you can still get the message even if it's read by the bios and OS, but the ssd is no longer reliable (happened to myself). Check your wire connections and if the problem persists pull the drive out and scan it in a cradle with a different PC if your machine won't boot and you're unable to install a HDD health scan program. Any external HDD casing will do, just take it apart and remove the OEM drive and put the drive you wan't to look at in the cradle and connect it with the USB and run a HDD health scanning program to be certain. (I use HD Sentinel but there are many others) Good luck!
