Sony Vaio VGN-AR71J Windows 7 upgrade issue
The solution which I'm about to provide you will erase all the data from your laptop hence, data backup is what you shall think first.
In order to do a fresh install on your laptop you are first required to format your HDD completely. You are required to delete all the partitions on it and recreate new partitions. Your version of Vista home is not allowing to upgrade to windows 7 because both of them are through Microsoft. You have three options at this stage to completely format your HDD
1. Use a DOS bootable CD. Go to any XP PC. Put a new CD inside it right click on CD driver in explorer select Format and then check on create a DOS startup disk. It will make a dos bootable CD put that CD in your laptop and boot through CD it will take you to command prompt. In command prompt you type format C: then again type format D:
do it for all the partitions your laptop has if format doesn't work then you can use deltree command. Once the partitions are formatted you can boot through your Win7 CD and install the OS.
2. Use a linux installer CD. boot through Linux installer CD install linux on your laptop and then install win 7 on it.
3. Use a third party disk management tool through which you can boot and erase all the partitions on your laptop.
