Well If you are a windows XP lover and still want the better advancements of Windows 7. Then why not install both of them? Yes windows allows to install two or more operating systems. It leave each other systems intact as long as you don’t install them on same partition.
To install two OS on same computer, You must have two different partitions. One for XP and one for Windows 7. Well, 70 GB each would be enough for smooth running.
For now Let us Assume that You have Windows 7 Installed on your computer(take it vice-verse if you installed xp already) . The Windows 7 Must be installed on C: (common thing) and now assuming that there is another partition D:(minimum disk space of 10GB). Copy all the important stuffs from D: if you have any cause we are going to format it to install the windows XP . Now after emptying the D: drive put windows XP CD into CD drive and restart the PC.
Make sure you have set First Boot Device as CD ROM, to do this you must edit settings in BIOS. You can enter BIOS setup by press DEL or TAB or F1 or ESC it really depends upon the computer. After enetering into BIOS setup menu choose Advanced Settings, in there must be First Boot device Setting set it to ” CD ROM” now save and exit.
Now Computer Must restart and it may ask if it should boot from CD? Hit any key to boot from CD. Now windows setup will start loading, after sometime the installation process starts, It asks in which drive to be installed here you choose drive D: , The drive which you cleared before. It starts formatting and after few secs it restarts on its own, and the setup continues, Complete the setup as usual. Remove the setup CD. Restart the computer, now you can set First Device to Normal from BIOS. But before the Window boots it gives you two options, Boot Windows 7 or The windows XP you choose whatever you want.
But remember Install the application appropriate to the operating system because you cant run all the application on both OS with single installation, you need to install them separately. Try to keep ’em apart. Thank you.
