I have a brand new HP Pavillion dm4. I bought it so I could use it to dual boot Windows 7 (Home, preinstalled) and Windows 8 (consumer preview).
The disk is a dynamic disk with 4 partitions. I've done some research and understand that I need to have a basic disk in order to install Windows on another partition.
I've found an article
on sevenforums.com on how to do this, but it does not work. I have a system partition and the OS sits on the C: partition. I can not delete either of these volumes, neither with the GUI nor with the elevated command prompt and diskpart.
I've been able to delete the other two volumes (recovery partition and HP Tools) without problems.
I don't care about any data on the machine, since I have not yet saved anything. I just want to be able to dual boot Win7 and Win8.
Please don't recommend using a VM for Win 8. I'm aware of that option, but I prefer the dual boot setup.
