Trying to Multi-boot Windows 7 with 10

I only have windows 10 pre-installed on this laptop, and I am trying to currently install this windows 7 os it as well. I only can use the same drive, C:\ drive as a partition. The setup goes directly to the error code "0x0000428" which is a driver signature failure. I've tried to find a way to disable that in my BIOS but my laptop doesn't have the IDE mode, though it does have a Legacy Support mode which I did disable, but to no avail. I don't know how this will end up working, can anyone please help me?

Welcome to the forum.

You must edit your profile and add ALL hardware specs.
If the laptop is new and came with Win 10, maybe it's impossible to install win 7 on it.
- To begin with, you must disable fast boot and secure boot (sometimes it has another name) on BIOS.
- New chipsets (Skylake and Kabylake) only have USB 3 ports. Win 7 installation disk doesn't have USB 3 drivers. You will have to add them to the Win 7 installation disk.

After you edit your profile and add ALL hardware specs we can search to find a sulution.

You have to install th eoldo/s first or it will destroy the new boot sector as it wont understand it. Simple andswer is run 7 as a virtual pc with free Virtual box Downloads – Oracle VM VirtualBox

Hello, I've updated the information on my profile. How do I find out the info about the chipsets in my laptop?

Your computer was designed for Win 10. That doesn't mean it can't have Win 7. Depends on your BIOS. If you can't disable Secure boot, win 7 can't be installed.

What kind of license is your Win 7 and what brand (Home, HP, Pro or ultimate)?
When you boot from Win 7 installation disk, do you have mouse and keyboard?

Yes, I can enable/disable secureboot.

Hello, again. I have installed Windows Home Premium just fine now after enabling CSM in the BIOS.
After I installed a few of the drivers since they were wiped, I went to the mice and other pointing devices... It wasn't there, so I checked for the downloads on the Asus website, and they currently do not support (with my unit at least) Windows 7, so I fear this may have been a waste of time for me unless there is another way that I can use my touchpad without it. The program is called Asus Smart Gesture, only usable on 8, 8.1, and 10.
I don't know if I should just buy an optical mouse for when I use Windows 7 or just forget about it and delete it entirely?

- On BIOS, disable secure boot and fast boot.
- See if it boots normally on Win 10.
- Make the rescue disks so you can reinstall win 10 if something goes wrong.
- Backup your data on an external disk.

As Win 7 installation disk has no USB 3 drivers, you will need to add them to the installation disk.
Asus, MSI, Gigabyte and Intel has a program to do it.
Download Windows 7* USB 3.0 Creator Utility.
As those programs only install the USB 3.0 drivers to the installation Wizard, you may end with Win 7installation without mouse and keyboard.
