How to have Dual Boot Option on PC even after installing earlier versions of Windows later
One can have dual boot option on PC to boot multiple operating system on single computer. For example, you can have Windows XP, Linux, Vista, Windows 7 etc on single PC by installing them in different partitions. But to have that dual configuration, you will have to install the latest version after the earlier ones. For example, you can have dual boot option if you have installed Windows 7 in different partition on a PC with already installed XP. But if you will install XP after Windows 7, boot screen will not see any option to start Windows 7. But there may be a situation where you need to install Windows XP on your pre-installed Windows 7 PC.
Few days ago, I purchased a Tata Photon Plus mobile Internet data card which was suppose to run smoothly on Windows 7 but that didn’t happen. The device started facing some issue with the Windows 7 64 bit driver. Then I thought to have Windows XP in another partition so that I can still run Tata Photon Plus over there. But as I said, if you install the earlier version of Windows after the later one, you will not get dual boot option as the boot configuration file will be overwritten by newly installed windows file which is not the updated one. But I installed Windows XP on a pre-installed Windows 7 PC and made some changes to get the dual boot as well. Here is the way to get that.
So I installed Windows XP in different partition of my computer hard disk and then lost Windows 7 boot option. After the successful installation of Windows XP, computer started properly but with only XP. To get the dual boot option and get back Windows 7 boot option, you will have to follow below steps,
Steps to get dual boot on PC even Windows XP was installed after Windows 7
1. Start your computer (It will start with Windows XP)
