Problem Infinite loop installing Mac OS Sequoia on 2016 MBP

I have a problem installing Mac OS Sequoia. Goign through the entire process, described below, the mac keeps on booting up from the flash drive to the screen with the 4 option (see image in step 22 below). It never finishes the Mac OS install process.

Here are the steps I took:

  1. Boot Mac OS holding down Option+Command+R to initiate Internet Recovery
  2. Disk Utility - Erase SSD and select APFS file format naming the hard drive as Macintosh HD
  3. Go through process to install Mac OS Sonoma (latest Mac OS supported on this Mac)
  4. After installation, install all possible software updates.
  5. Download OpenCore-Patcher.pkg from https://github.com/dortania/OpenCore-Legacy-Patcher/releases/tag/2.4.1
  6. Launched the Open Core app
  7. Clicked Create macOS Installer
  8. Clicked Download macOS Installer
  9. Selected the latest macOS Sequoia in the list, then click Download
  10. Inserted a 256GB USB-C SanDisk flash drive into the USB-C port
  11. Clicked "Yes" when asked Create macOS Installer?
  12. Clicked the displayed Install macOS Sequoia
  13. Clicked on the SanDisk displayed
  14. Then clicked "Yes" on the Are you sure you want to erase 'SanDisk Ultra'? All data will be lost, this cannot be undone.
  15. After installing the installer on the flash drive, clicked "Yes" on Installer created successfully, would you like to continue and Install OpenCore to this disk?
  16. Then clicked on Install to disk on Finished building your OpenCore configuration! Would you like to install OpenCore now?
  17. Selected the SanDisk flash drive from the list
  18. Clicked on "reboot" in the next window OpenCore has finished installing to disk. You will need to reboot and hold the Option key and select OpenCore/Boot EFI's option. Would you like to reboot?
  19. While rebooting I held down the Option key on the keyboard
  20. In the bootup menu I selected the "EFI Boot" option
  21. In the next menu selected "Install macOS Sequola"
  22. In the next menu selected "Install macOS Sequela Use the attached installer to Upgrade or Install macOS."

  1. Selected the Mac's hard drive to install Sequoia on
  2. After installation and reboot a few times, the screen in step 22 keeps coming up.

Am I doing something wrong? How do I correct this.
