While Installing Windows 7 when you can asked to ” Where do you want to Install Windows?” select the drive you just created.
- Finish up the installation and the PC restart and now you`ll be able to see Windows 7 and Windows Vista in the boot menu.
Now once Windows 7 is fully installed, you`ll see that you wont be able to access the Windows Vista Partition now because both the drive are named as C.To solve this issue do the following :
