Are you trying to install Win7 yourself, from scratch, as a new/second Windows on a P51 that was delivered with Win10 installed?  Or what?

 

Please read this other thread, which deals with installation of Win7 from scratch to NVMe target on a P50.

 

And in particular read my post regarding use of the Gigabyte USB Install Utility which creates new bootable Win7 install media on USB by adding the required and missing USB 3.0 drivers for mouse/keyboard as well as the missing NVMe driver for NVMe target devices.

 

The original retail Win7 install media on CD/DVD did not support USB 3.0, nor did it support NVMe.  Drivers for both of these device types must be added to the Win7 install media in order to now install Win7 on Skylake-based motherboards, for both laptops and desktops.  You can use the Gigabyte utility to "slipstream" add the missing drivers to either (a) CD/DVD original Win7 install media, or (b) ISO file version of original Win7 install media, with the newly combined output being written to a new bootable USB version of Win7 install media.

 

This new USB bootable Win7 install media will have the missing drivers present and will solve your problem.

 

Note: for quick reference I quote my own posts on that other thread...

 

The Gigabyte utility is available from the Gigabyte download site, scrolling down on the page about midway (you may need to expand categories to see everything).  It is described as: "Windows USB Installation Tool, (Note) Support Intel 100/200/X299 series motherboards. OS: Windows 7 64bit,Windows 7 32bit".

 

The direct link to the utility on that page is here.

Hello, Thanks for quick reply!!!

I am tring to clone from a P50 image onto P51 hardware using SPX (shadow protect)

It requires the .inf and .sys driver files.

For the Gigabit link, which drivers can I use for the P51 hardware I have listed?

Thanks!!!

Looking inside the expanded ZIP file that is the Gigabyte utility, there are two sub-folders with the two drivers.

 

(1) Samsung NVMe driver

 

 

(2) Intel USB 3.0 driver

 

 

I looked at the INF for the Samsung NVMe driver and it doesn't exactly match the device type in your P51.  I suspect the Lenovo version of the drive is an OEM model, and the Gigabyte utility driver is for a somewhat different model.  I don't know if you can just point "update drivers" to that folder and it will work, or if it will not find a match.  You can try it.

 

Furthermore I believe if you go to the Samsung download site and retrieve their NVMe driver it will most likely be for their own retail products, not the Lenovo OEM version.  I can't say whether the driver will or will not work for your P51.  Again, worst case you can try it.

 

As far as the USB 3.0 driver I'm reasonably certain you do "update driver" and point to the Gigabyte driver folder and it should probably work.  Worst case you could try the driver download page for P50, select Win7 64-bit OS, and then expand the USB category.  You'll find the Intel USB 3.0/3.1 drivers for the P50 and these might work perfectly for the P51 as well.  Try it.

 

As for the ACPI device, I don't know.  Sounds like a chipset category issue.
