so ignore me, "you did it already so why bother..."
First of all, this is my 4th day searching all over and trying many things. I hate when people ask instead of search, I tried everything before bother you guys but I really apologize for this post.
I have a Dell T5500, it takes me 5 days to finally install Catalina. The big problem is the BIOS on Dell. Later on, I will put here the only BIOS configuration that finally works.
Probably my main problem is my cheapness, using old graphics cards but I really think the one I am using still has some more to give me.
If you guys think the problem is the Graphics card please let me know and we can go from there.
So, this is what my system is showing:

iMac (27-inch, Late 2013)
Processor 2 x 2.93 GHz Quad-Core Intel Xeon
Memory 36 GB 1333 Mhz DDR3
Startup Disk Catalina
Graphics NVIDIA Chip Model 3 MB (I know, it should say "CHEAP" Model)

The card I have there is an Nvidia GeForce GTS450 1Gb

I can only have 1024x768

The other problem I have is I can only boot from the USB, I copy the content of the EFI from the USB to the empty EFI in the HardDrive but nothing happened.

I know nothing or little about this, so please when you explain, please think you are talking to a freaking stupid.

T5500 BIOS configuration

If the hard drive is SAS you can't boot off of it. I know this is an old thread but wanted to chime in and ask a question as well? Where you ever to resolve your other issues and run Catalina?
