Hi, I have created an usb with Catalina (downloaded from app store) and opencore with custom config.plist and kext for my motherboard and chip.
The usb runs ok. I can use utility disc for formatting the ssd, but when I try to install catalina and select that ssd, installation asks for Admin user & password.

I´ve tried to ressetpassword in terminal but the window that opens is in blank.
I´ve tried to Single user boot and mount the drive with /sbin/mount -uw / and rm /var/db/.applesetupdone for reseting asking for password but it says that can´t write in this volume.
I´ve tried to use root & niresh and nothing, I´ve tried with the admin user that created the usb and nothing.

Can someone give me some help?

Motherboard: AMD aourus b450
Chip: AMD Ryzen 2600

Thanks in advance
