I'm running a Toshiba laptop with 320 GB hd, WinX 64 bit and am trying to create a dual boot but it isnt letting me. Im trying to install windows 7 home premium 64 bit to enable me to run programs not yet available to WinX via Windows 7 which will run the programs but upon entering bootable ISO for Windows 7 64bit, and selecting the disk 0 Partition 4 (39.1gb total size, 38.9gb free space, type dynamic with NTFS formatting) and im getting an error message, "Windows cannot be installed to this hard disk space. The partition contains one or more dynamic volumes that are not supported for installation." How can i make it run Windows 7 dual boot alongside my WinX? How can i get it to install Windows 7 on that particular partition?
