Windows 7 x64 install (BIOS problems)

[valves]

I have a motherboard GIGABYTE B150M-D3H DDR3.
Can you help me please?

I have problems to pass Windows 10 to Windows 7.

Where are in the bios of my motherboard the steps 1 and 2? I don´t find them.

Step 1: Change Mode UEFI Bios to Mode Legacy
boot > boot mode (enter) > select legacy bios (enter) > save changes

Step 2: Disabled Secure Boot
authentication > secure boot (disabled)
boot > Launch csm (always) > save changes

Thanks!

Hi valves, welcome to the Forum.

If you want to get into the BIOS, press the Delete key repeatedly just after starting the computer. This should open the motherboard set up so you can change various items which can be found by paging through the various screens while you are in set up.

Gigabyte GA-B150M-D3H - How to Install Windows 7

GIGABYTE Tech Daily: Having Trouble Installing Windows 7 By USB With Your GIGABYTE 100 Series Motherboard?

The problem lies in the fact that Windows 7's installer is only compatible with an older type of USB driver. The GIGABYTE 100 series motherboard uses a newer kind of USB driver, meaning you will get an error when trying to install Windows 7.

Thankfully there is a fix for this which allows you to package the updated driver on to your USB driver.

I have a GA-Z170-HD3P and, despite the manual says that This item is configurable only when Windows 8/10 Features is set to Windows 8/10 or Windows 8/10 WHQL, some options also are present when OS=Other
When OS=Other secure boot is automatically disabled.

Storage Boot Option Control
Allows you to select whether to enable the UEFI or legacy option ROM for the storage device controller.
Disabled - Disables option ROM.
UEFI Only - Enables UEFI option ROM only.
Legacy Only - Enables legacy option ROM only. (Default)

Other PCI Device ROM Priority
Allows you to select whether to enable the UEFI or Legacy option ROM for the PCI device controller other
than the LAN, storage device, and graphics controllers.
Disabled - Disables option ROM.
UEFI Only - Enables UEFI option ROM only. (Default)
Legacy Only - Enables legacy option ROM only.

Set both option ROM to UEFI and create a USB Win7 installation:
