I have an HP Probook 4530s that has Windows 7 Home Premium 64 bit. The laptop has a 500 GB hard drive and 8 GB memory. I downloaded Windows 8 and created a bootable DVD. Following several different suggestions from the net I've created an unallocated partition on the hard drive. Originally there were 4 partitions on the drive. A System partition, C: partition, HP_Recovery partition D:, and HP_Tools partition E:. And now I've created the unallocated partition so there are now 5 partitions on the drive. When I boot from the DVD it starts up like it's going to install Windows 8. I enter the Product key and select Cutsom install. I get a screen that shows all the partitions and when I try to select the unallocated partition I get the following message: "Windows cannot be installed to this hard disk space. The partition contains one or more dymanmic volumes that are not supported for installation. Windows cannot be installed to this hard disk space. The selected disk has the maximum number of partitions of this types." I tried formatting the unallocated space before attempting the Windows 8 install and get the same message. But, when I select the C: partition I don't get the above message. What am I doing wrong?
