2. First install Windows 98.

3. After this, insert the XP CD and click on install.

4. You will get two options -- upgrade or new installation. Select new installation.

5. Click on advanced tab in the next window.

6. In that tab, choose "I will specify the drive" then go ahead.

7. Your system will reboot and then it will ask to format the drive in which you want to install XP. By doing this, you will get both OS running on the same machine.

=======================================================

Updated For Those Who Wish To Run Windows 98SE along with Windows XP on Hard Disks Greater than 40GB.

Since Windows98 only supports a Maximum 40GB Disk Size.

To create a partition, first, boot your computer with a Windows XP CD.

• Create Partitions desirably.
• Next, Format the C Drive (or your desirable drive) using the FAT32 File-system.
• After the Setup has formatted it, it will start copying the files of windows XP in it. Hard Reset on that point (Press the small button beside the power button of your Computer Tower)
• Again, boot with Windows XP, and this time, format the D Drive (or your second desirable drive) with FAT32 (Not NTFS as if you will format with NTFS, Your Windows 98 will not be able to access the files that you store in windows XP)
• Again, after it will finish the format, it will start to copy the files. Here, Restart the computer again.
• Now install Windows 98 normally.

And now follow the above procedures!

Yes it is possible to repair windows XP: follow this step:

• Set your first boot device in the Bios to CD-Rom. Insert your Windows XP CD, save the bios settings and exit. Soon "Press any key to boot of CD" will appear on the screen, hit the space bar to continue.
• Now setup will inspect your hardware and software, it then will load various files required for the repair. Just wait and be patient, this may take a few moments.
• Soon a menu will appear (as pictured below), press enter to continue.
• Now the "End User Agreement" Press "F8" if you agree, "ESC" if you don't.
• You will now have to select the installation you wish to repair. Usually there is only one, but sometimes, there may be 2 or more (i.e. you have done a parallel install to resolve a problem), use the up/down arrow key to select the install, and then press "R" to continue.
• Setup will now examine the disk be patient, it can take a few minutes.
• Setup will go through a percentage - 1 to 100%
• A screen will soon appear. Press "F3" to continue
• Now setup will reboot system, wait 15 seconds or just press enter.
• Now it is time to see if this has solved your problems.

: Yes, You can repaire windows without data loss.

Here are opinions and answers from Wiki s Contributors:

• Find out more from the readme.txt that comes with the start up disk.

• You simply go into the control panel (which you find in My Computer) select 'Add/Remove Programs' icon. A window pops up. Now click on the tab along the top called 'startup Disk' then follow the instructions. Make sure you have a floppy disk, preferably one you just bought or have formatted.

• To reformat your hand drive using Win98 you need a Win98 boot floppy with reformat and fdisk options on it. To get started, insert the floppy and reboot the system. After the boot you will get a screen that asks you if you want to start windows with CD-Rom support, press the shift and F5 keys and you will get the prompt (a:\) type format c:/s This will reformat your hard drive with the system tools installed. If you need to create a new portion follow the steps above and when you get the a:\ prompt type fdisk and follow the instructions.

• I have reinstalled Windows 98SE after reformatting my hard drive several time. I was never able to directly install SE. First I had to install Windows 98, then insert the 98SE CD and go through the whole installation process again. I could never figure out why I had to first install 98 and then SE, but at least it works for me doing it that way.

• If you had Win98, and then bought the upgrade, you would need both disks to reinstall. Start with the new disk, the upgrade. At some point it will ask you to insert the old disk into the CD drive, so it can verify that you actually had a copy, and weren't just trying to get the upgrade because it costs less, without buying the original or older version. Sounds like that might be what happened.

Differences between Windows 98 and Windows XP are:

• Win98 has a FAT file system, XP supports NTFS as well.
• XP has a system restore feature
• Some Windows 98 machines do not have USB ports.
• XP has a Firewall provided.
• For XP, additional ZIP archiving software is not required.
• Win98 has security issues and Microsoft ended support for it in 2006. Support for XP was ended in 2014.
• Windows NT based architecture with multi-processor support. Security and performance increases by 25-50% with upgrade from Windows 98 to Windows XP. Of course you also need a computer with 10 times more RAM and a much faster CPU to support all of the processes utilized.

Both Dos and Windows are Operating systems. But, they possess some features which make them differentiate. These features are listed below:

"«Dos is only single tasking while Windows is multitasking.

"«Dos is based on plain interface while Windows is based on Graphical user interface (GUI).

"«Dos is difficult to learn and understand while Windows is easy to learn and understand.

"«Dos is less preferable by users while Windows is more preferable operating system.

"«Limited users can work on dos while in Windows there are many users.

"«We cannot see mouse in Dos while in Windows we can see and use mouse to click on icons or links.

"«Simple text commands are written in Dos while in Windows we operate computer with the help of mouse.

"«In Dos we cannot Play games, watch movies and listen songs while in Windows we can enjoy playing games, watching movies and listening songs.

"«In Dos new hardware cannot work properly while in Windows it can detect and installs software automatically.

"«Application and system software¡¦s did not work properly in Dos while in Windows it runs at a great speed.

"«Dos is not user friendly while Windows operating system is user friendly.

"«Dos performs operations speedily as compared with Windows operating system.

Windows programs, on the other hand, realize that they must share your computer with other Windows programs. Actually, did you know that Windows 3.x itself is a DOS program? What this means is that Windows has control of the computer's hardware, and in turn it shares parts of the computer's resources with Windows programs. The obvious advantage to this arrangement is that you can do several things at once; for example, you could play Beethoven's 5th, start downloading a file from a BBS, then look at your checking account and use a Calculator to check the balance all at the same time. Another advantage is that you can share data between programs; for example, copying a spreadsheet summary into a work processor document.

The important thing here is that many DOS programs will run poorly or not at all in Windows. For example, if you try to run Microsoft System Diagnostics (MSD) while you are in Windows, you will get the message:

You are running Microsoft Windows.

MSD can only report information specified by it's associated Windows Program Information File (.PIF). Therefore information presented may be less accurate or complete than if MSD is run outside of Windows. For more accurate information please exit Windows and run MSD from the MS-DOS prompt.

Some areas may be affected while MSD is run under Windows: Memory values and types will reflect what Windows provides by itself, and through the associated .PIF file; IRQ values may be reported differently; and the visual memory map in Memory, Memory Block Display, and Memory Browser may show different results. Other areas that may be affected include Video, OS Version, Mouse, Disk Drives, and COM Ports.

So how do you know whether a program is made for DOS or Windows? Nearly all Windows programs bear the Microsoft Windows logo Microsoft Windows compatible, while DOS programs do not. If you're still not sure, try running the program from the DOS prompt first. For example, type calc at a DOS prompt; you will get the message:

This program requires Microsoft Windows.

NOTE for Windows 95/98: if you try running a Windows program from the Windows 95/98 command prompt, the computer will simply start Windows (if it isn't already running) and run the program.

A word of warning for Windows users: in the Main group there is an icon called MS-DOS Prompt. This is not the same thing as running in DOS. It will let you run some DOS programs, such as the command prompt or the EDIT program, but it is still running on top of Windows. The proper way to switch from Windows to DOS is to close or exit all of your Windows programs, including Program Manager.

Windows 95/98

One way to switch the computer from Windows to DOS mode is to click on the Start menu, then Shut Down, then choose "Restart the computer in MS-DOS mode". Doing this will close all Windows programs and (mostly) remove Windows itself from memory.

Another way is to adjust the properties of a DOS program. Right-click on your program (or its shortcut), select Properties, open the Program tab, and click on the Advanced button. In the Advanced Program Settings you can set the program to run in MS-DOS mode, and even specify a starting configuration just for that program.

Windows is a GUI (Graphical User Interface).

When working with a CLI, you begin with a blank screen and a command prompt. At the command prompt, you type commands, one at a time, for the computer to process. (i.e. "MKDIR C:\MYDIR" to create a directory called "MYDIR" in the root folder of the C drive) Any programs (text editing, database, etc) are run from the command prompt by directing the computer to the location of the program, and typing the execution command.

Example (Text in italics are commands, other text is command prompt.):

C:\> ''CD PROGRAMS''

C:\PROGRAMS\> ''CD GAMES''

C:\PROGRAMS\GAMES\> ''CD PONG''

C:\PROGRAMS\GAMES\PONG\> ''PONG.EXE''

At this point, PONG would take up the entire screen, leaving you unable to do anything but play the game until you exit the game. After you exit the game, you would be brought back to the prompt:

C:\PROGRAMS\GAMES\PONG\>

On the other hand, a GUI offers much more flexibility by using icons and windows to represent objects and programs. With Windows, you can open several different documents or programs, and easily switch between them. Also, there is the Start Menu, from which you can launch program shortcuts instead of having to wade through the entire file directory to execute your choice of program.

The interrelation is that Windows was originally a program ran to top of DOS. In order to use Windows, you used to need a line in your AUTOEXEC.BAT (a script file that automatically executed on DOS startup) that pointed to the Windows program. Windows versions 3.x - 9x and Me still run on top of DOS. What this means is that those versions of Windows aren't really Operating Systems, because they rely on DOS to process all the programs. All those versions of Windows do is make the programs easier to get to and switch between. Windows NT versions, and the Windows XP/2K line are built on their own system kernel so they are considered true Operating Systems on their own.

On Windows XP, you can get a version of it by pressing Start -> All Progs -> Accessories -> Command Prompt. This is an updated version of the original DOS which would run in fullscreen and be the only thing on the computer. You can get started by typing ''HELP '' to see a list of commands. For info on a particular command type '' /?'' .

1. DOS does not supports GUI, Windows supports.
2. DOS does not supports networking, Windows Supports.
3. DOS is a single user OS, Windows is a multi-user OS.
4. DOS is a single tasking OS, Windows is a multi tasking OS.
5. DOS does not supports threading, Windows Supports.
6. DOS supports maximum 2 GB of partition, Windows supports 2 TB or more.
7. DOS supports FAT 16 file system only, Windows supports FAT 32 and NTFS.
8. There is no server support in DOS, Windows has.
9. DOS is not as stable as Windows.
