Lenovo desktop win 8 will not load windows 7 as a dual boot

I have a new Lenovo Desktop computer preloaded with Windows 8.  I want to dual boot with windows 7 HPrem.  I create the new partion and start the install from win7 disk.  on first reboot the boot loader screen comes up and says there is an unsigned driver.  I disabled the detect unsigned driver in the bios but I can't get the win 7 to load.  I have another lenovo desktop that came with Win7 and I loaded win 8 with no problem as a dual boot.  What am I missing here??
thanks

I think the machine should have Windows 7 loaded first and then Windows 8 as with the other machine.

Why not, as an alternative, load Windows 7 as a Virtual Machine. That will work for certain and you can use both systems simultaneously. You can use VMware Workstation, VMware Player, or Virtual PC to create a virtual machine.

This will save you time in the long run.  .... Thinkpads_User

With Windows 8 you have Hyper-V included, so you don't need the type 2 hypervisors like vmware workstation, player, Virtual box or Virtual PC (some of which have been mentioned by thinkpad's). With type 1 hypervisors like Hyper-V the performance of your VM will be much better.

Otherwise, I'd also think that you'd have to install the older OS first to get dual booting running correctly. At least it used to be that way with previous Windows versions....

Can you press F8 at the beginning for the  Advanced Boot Menu, then Disable Driver Signature Enforcement? What happens when it tries to load? Does it BSOD? If it does, what is the BSOD?
Your help has saved me hundreds of hours of internet surfing.

I have disable driver Signature enforment.  Then win7 starts to loads but hangs and never finishes the boot.

If I were the end user I would load 7 in VM.  It is for a client (low end user).  Its hard to find computers local with 7 installed.  I had no time to order one.
 
I will try to wipe and load 7 as a primary os and then load 8 as dual 2nd.

thanks guys .....I'll get back with results.

Does it hang with the loading bar? Have you tried the other options like Safe Mode or Last Known Good Configuration?

Make sure you create recovery media so you can restore the system to factory defaults first.

hangs at the 7 logo.  

I'm going to put in a different drive so I can preserve all the Lenovo recovery partions.
I'll try it tomorrow......

thanks all.....and Happy New Year!    I report back.

Personally I don't think virtualization should be a problem, even for a PC illiterate! Just install it.

the EUFI seems to be the issue.  Does anyone know if I had Win 7 loaded first would it allow win 8 install?

I did look at Start8 and seems to be a REAL possiblity.  Testing on my computer now.

Wow....Microsoft sure does want us to go to Win 8 real bad!

Thanks for all the great advice....I will award points soon.
