Catalina Patcher OCLP EFI boot option persists

[snomelc]

I have a 2011 Mac Mini (5,3) and just installed a brand new SSD, then fresh installed Catalina using Dosdude's Catalina Patcher. The installation and post-install update went well. After all was done, I did delete two unmounted volumes using Catalina Disk Utility diskxxx and Update. Then I installed Bootcamp Windows. All works well but my question is: Should there be an OCLP EFI boot option? (see attached JPG...Catalina is on the Samsung SSD) If not, how do I get rid of it?

You need to clear out the EFI booter not used by DosDude's patched Catalina.
Go to terminal and type:
sudo diskutil mount disk0s1
Type in your password. Go to the EFI disk (/Volumes/EFI) and delete all contents.

Not that this applies to older systems like yours not using EFI Windows boot. BootCamp on those uses an emulated BIOS.

In Terminal 'sudo diskutil mount disk0s1' > Volume on disk0s1 failed to mount

Don't know what to do.
