Once the UEFI is setup, Save & Exit Setup

Installation

The installation step is simple.
Plug your Bootable USB Flash Drive to the target system.
Turn on your system.
3. Boot to Boot Menu using F12
4. Select your USB Flash Drive with the UEFI prefix and press enter to boot.
5. When at OpenCore menu, select ResetNVRAM and boot from it.
6. Repeat step no. 5.
7. When at OpenCore menu, boot using Install macOS Big Sur. It will take couple of minutes to boot into installer screen. Once you reach the installer, select your preferred language and continue.
8. On top, click on Utilities and then select Disk Utility.
9. When at Disk Utility, click on View and select Show all Devices.
10. Select your target SSD. Do not select the partition
11. Click on Erase button and erase the drive with following parameters.

Name	Macintosh HD
Format	APFS
Scheme	GUID Partition Map

12. Close Disk Utility.
13. Select Install macOS and continue with the options.
14. Select Macintosh HD and click on Install.

This will take couple of minutes and will restart at "Less than a minute is remaining". Upon completion, the system will automatically restart. The System will restart to complete the installation. Here it ends the first phase of the installation.

After installation, boot it using USB, but this time select Macintosh HD.
The first boot maybe slower as the caches are not build yet. Once the caches are built, it will boot normally.
When you're at the welcome screen, continue with the basics options such as Keyboard setup, Network, Computer Account and Privacy settings.

Now the installation is complete, but the drive isn't bootable yet. You need to complete the Post Installation

Post Installation

Now, configuring the Post Installation. There is not much to do for the postinstallation except configuring WiFi/BT and the boot from system drive. Everything rest is fully functional.

WiFi/Bluetooth
The stock card has been replaced with Broadcom BCM94352Z. To activate the WiFi and Bluetooth, you'll need to install some kexts and add some patches. For more information, read here:
