Microsoft Windows 7 Home Premium 64-bit 7601 Multiprocessor Free Service Pack 1

it happened to me as well when i was trying to install Windows XP as dual boot with windows 7 home premium
i always get the blue screen due to the SATA driver that xp doe snot recognize my HD,,
but the people in the forum really do good help by pointing me to virtualize xp INSIDE W7..
IT works using VMware , why do not you use the same thing
or do you have another purpose of installing w8 as dual boot with w7

You need to boot the DVD, not start it from the existing Windows 7 installation.

See here: Dual Boot Installation - Windows 8 and Windows 7 or Vista

To be sure you're booting the disk follow How to Boot A Computer from CD or DVD - YouTube.

If it still fails, where did you get the Win7 disk and how is it burned?

Is there any chance the Win7 is installed to a UEFI BIOS? If so it will have a EFI System partition in Disk Mgmt.
