I upgraded from Mojave to Catalina using the apple update.
Went through the cycles of install reboots until it booted from the OS drive.
Then it hangs towards the end of the boot and then reboots.
I did a verbose boot and it seems to be getting stuck on the internal graphics
See screen shots and a copy of the kexts I have in clover.
I also cannot seem to boot from my USB backup (clover does not list the partitions on my usb disks) so I cannot currently give you the list of kexts in clover.
I appreciate any suggestions.

THANK YOU! That totally worked.
Should make this permanent y adding it to the plist?
And will I need it later when I reinstall a graphics card?
Here is my clover EFI. (now that I'm able to mount the EFI partition)
Is there anything in there that is causing this?

Thank you for all the help.
Now works like a charm.
And in the process I figured out how to remove the debug at boot.
Is there a way to mark this thread as solved in the title?

Guys I need a little bit of help here. I'm driving crazy. The first stage of the installer goes perfect. But the second instance starts and at remaining 12 minutes stage boom. Restarts. Agdpmod=pikera -disablegfxfirmware
Been trying with those with no luck. IGPU is disable.
