Ques. I bought a hp G6-2302AX laptop, as it was loaded with Windows8. What I want is want to dual boot it with windows7, is it possible to install win7 it with pre installed win8. First is it possible, if yes then, please tell me, with full detail, how to do it.

Ans. Be advised, performing this procedure might be in violation of HP's warranty terms and conditions. Please check the same with the company before going through with it.

Please follow the below listed steps:

1. Making a new partition.

Follow these  steps only if apart from 'C' drive in your computer (Winkey+E -->computer) you do not have any other drive > than 25GB in size in your laptop.

  • Hold the Windows logo key on your keyboard and press “R” (Winkey+R). This will launch the Run the utility. Type “diskmgmt.msc” inside the text box and press Enter. This will open the Windows Disk Management utility. This is where you can format, create, and delete hard drive partitions.
  • In order to create a partition, you need unallocated space. Unallocated space is basically disk space that is not formatted or not prepared for storage. Formatting is the act of preparing a disk space for storage. It similar to building a foundation for a place to be inhabited. Thus, unallocated space is just useless blank space with no “foundation” or format.
  • To create unallocated space, you need to shrink your hard drive. When you shrink your hard disk, the remaining space becomes unallocated.
  • To do this, right-click your main drive and select “Shrink Volume.”
  • Now you need to enter the amount you want to shrink the hard disk by in megabytes (1000 megabytes = 1 gigabyte). For example if you want to create a 30 gigabyte partition, enter 30,000 megabytes in the text box. Now click “Shrink.” (please allot atleast 30GB of space for windows 7 to run properly)
  • The Disk Management Utility will show you the maximum amount of shrink space available. That’s the maximum size that can be allocated to the new partition.
  • You will then see the region of unallocated space (shaded black). Remember, this space is not yet usable.
  • Now you need to create “foundation” or format for the unallocated space. This will allow for the space to become usable.
  • Right-click the region of unallocated space and select “New Simple Volume.”
  • This will launch the New Simple Volume Wizard. This will guide you through the installation process.
  • Assign the disk a drive letter. You can choose any drive letter that is not currently in use.
  • Select a file system for the disk. The file system is basically the type of format or “foundation” the storage device has. If you plan on installing a Windows OS to the partition select the “NTFS” file system.
  • Name the partition anything you like in the “Volume Label” text box.
  • Now click “Finish” to create the new partition.
  • If you now open the "computer" folder, you will be able to see the new partition. 

2. Installing Windows

  • Insert your Windows 7 disc and reboot your computer (you'll need to have enabled booting from your DVD drive in your system BIOS, but most PCs/laptops will have this enabled by default).
  • Once the DVD boots up it's a simple matter of following along with the fairly simple installation wizard. When you're choosing installation type, be sure to select Custom (advanced) and choose the partition you set up above. (Be careful here. Choosing the wrong partition could mean wiping your other Windows installation altogether, so make sure you pick the new partition you just created.)
  • After you select the partition, go grab yourself a drink and let the installer do its work. Windows will run through some installation bits, restart a few times in the process. Eventually you'll be prompted to set up your account, enter your license key, and set up Windows. When it's finished, you're up and rolling with your new Windows 7 installation.
