COMMON PROBLEMS INSTALLING WINDOW 7 AND POSSIBLE SOLUTIONS:

             * Windows 7 can’t boot from the installation media – Although  most computers can
                        boot from DVD, sometimes this capability is disabled in firmware. Set the boot order
                        in firmware so that the DVD drive appears ahead of hard disk drives and other bootable media.

* Hard Disk can’t be selected during setup – Although the Windows 7
                        installation media contains drivers for most disk controllers, Insert media
                        containing the required drivers and then click Load Drivers on the Where
                        Do You Want To Install Windows page. If the driver is on an internal hard
                        drive, press Shift+F10 to access a command prompt and then use Xcopy
                        to copy the driver files to a USB flash device or other removable media.
                        and then click Load Drivers to load the drivers from the media.

            * Forgot to modify the hard disk configuration prior to starting the
                        installation – On the Where Do You Want To Install Windows page, click
                        Drive Options (Advanced). You can then use the options provided to
                        create, delete, and format partitions as necessary. If you need to shrink or
                        extend a partition (even during an upgrade), press Shift+F10 to access a
                        command prompt and then use Disk Part to work with the partition. You
                        can extend and shrink partitions without having to delete them. Also
                        Disk Part can be use to change the disk type and partition style.
