I have a new Thinkpad P50 which came with Windows 10. Once I received it, I realized a couple of softwares do not work with Windows 10.

Then, ordered a brand new Windows 7 Pro OEM from Amazon to clean install on my machine. But the problem is that my computer no way lets me install it: - I can't change booting sequence in my BIOS _ have to go inside Windows 10 first! - After entering Windows 10, when I execute setup.ext in the Windows 7 DVD, it asks me for missing drivers without even mentioning which driver it needs. I called cutomers service, they are not able to solve this problem unfortunately! Thanks and I appreciate your times in advance. There are multiple utilities available from multiple vendors (including Microsoft, Intel, Gigabyte, ASUS, etc.) dealing with the missing drivers required to do a Win7 install on a Skylake-based motherboard. USB support for mouse/keyboard with Skylake requires USB 3.0 (no matter that the mouse and keyboard are USB 2.0 devices), and the original Win7 installer doesn't have built-in support for USB 3.

Similarly, if you want to install to an NVMe target device (rather than an ordinary 2/5' SATA HDD spinner or 2.5'/M.2 SATA SSD) you will also run into the fact that the original Win7 installer doesn't have built-in support for NVMe. It only supported IDE and SATA drives. The solution for both issues is to create a new updated Win7 installer (on bootable USB most conveniently) using one of the various available utilities which now contains the missing drivers. You just need your standard Win7 installer media (either on optical DVD, USB or ISO file) and the utility will 'slipstream' create a new updated output Win7 installer media on USB which now also includes the required missing drivers (at least the required USB 3.0 drivers for most utilities, and even the missing NVMe drivers from the Gigabyte utility). Note that ordinarily, on old machines (which supported mouse/keyboard from the BIOS with either USB 2.0 or via PS/2 connectors) you could always add any missing drivers early in the install using F6. You would then provide the missing drivers on some external media (floppy disk, USB, CD).
