Try using an internal drive as your installer. USB drive did not work for me either on the 5,1...

Upgrade to Catalina went fine, still no TRIM support though. Ugh.
I can give that a try. My problem is, with the video card I have installed, it doesn’t show the initial boot up so I can’t manually select the startup drive. Using the external USB stick made it easy because it would try booting to it first if I selected it as the startup disk before rebooting to install the patched Castilian. And if it didn’t work I could just unplug it and it would revert back to my normal boot drive... I can do the same with an internal drive and just unplug it if things still don’t work. Thanks, I’ll update once I’ve given it a try.

No
I’m trying to update an iMac 8,1 but I keep getting an error code (1) when applying post install patches
Catalina succesfully instaled in my Mac Pro 5.1, no patches post install, cause I have updated GPU and Wifi/bluetooth module.
Anyway I´m staying in Mojave meanwhile all my 32 bits software is updated.
Thanks @dosdude1

No... My machine is fully loaded with four 8Tb hard drives, two SSDs. Mojave Is is on one SSD, the other SSD is scratch while the four hard drives is for storage. i want to install Catalina on the second SSD. Leaving the first SSD untouched.

Try setting the second ssd as your 1st boot drive boot for Catalina to install and setup then after go to startup disk in system preference and then select Mojave as 1st boot drive

How do you upgrade to Catalina without the Mac EFI bootscreen? I'm in the exact same situation as you. We will not be able to see what's going on right? How do you do it "blindly"?

The "Install to This Machine" option should allow you to do a blind install. I would still recommend having an EFI-flashed video card in case there's an issue. Back up data of course.
Seeing the same issue myself. I have about the same set up too, MP 5.1 with a RX 580. Created a bootable installer on both an internal and external disk but seeing the same error in each attempt. Also noticed that all the disks on my system are showing up an unmounted in Disk Utilities when booted in the Catalina installer. Attempts to mount any of the drives kicks out an error message.
I've alwaqys disregarded those messages as attempts to download malware or ransomware. Idk why I got it and you didn't though. I think I'll run etrecheck to see if I actually have malware, just to be sure. I'll report back.
Thanks. Yeah, on some really rare occasions I'll go to a website that displays those pop up messages. I disregard them. Heck, even for those websites, a simple refresh clears them. But there are a few websites that those messages are persistent - Those I leave. Normally per session when I have my Mac running, I'll either run it once or twice Malwarebytes.

I have successfully installed Catalina on to my Mac Pro 3.1 using your Patcher.
Thank you for all your hard work. I have donated to your account in appreciation.

Succesfully installed Catalina on my Macbooc Pro 8.3 17", dedicated GPU disabled. However, Migration Assistant still don´t work. I wish we had a Continuity Tool for Catalina.
You mean to say 'discrete GPU disabled', right? Or I might be confusing the two definitions.
For a supported gpu like the RX 580 but without EFI so no bootscreen can’t I just set the CatInstall USB volume in your video as the startup drive in System Preferences and reboot without pressing the option key? The CatInstall setup system should include the RX 580 drivers imo.
Catalina on MacBookAir4,2 seems installing and working just fine except of broken graphics acceleration on the Intel HD Graphics 3000 GPU. I am getting insane CPU usage with video playback. When reading the first post and the webpage description, it seemed that only some older Radeon GPUs have these issues, but looks like this is not the case. There was also some similar feedback about this behavior earlier in this thread. So what is the current state of the situation regarding this issue? Is there a way to fix this, or are there any patches being under development right now, or there is little hope and we need to consider downgrading back to High Sierra or whatever? Thanks for all the efforts.
I've installed Catalina on my Macmini 3,1 patched with the APFS ROM tool.
Initially I tried installing from a partition on an external Firewire 800 HDD, I used that in the past to install High Sierra but the Catalina installer wouldn't reach the end of its booting process.
So I tried the same with an external USB HDD and this time it worked. I enabled trim using "sudo mount -uw /" before "sudo trimforce enable" and it worked.
First impression with Catalina is it's a bit slower on my machine than High Sierra but it's a first release so it isn't a fair comparison, though I'll continue booting HS until Cat settles in a couple of point releases.

Can you not just run "sudo mount -uw /; sudo trimforce enable" to enable TRIM support again?
when new released of Catalina will come out - can we just update over the air or must reinstall from the USB installer again?
After letting my MacBook air settle down everything is working fine. Still no patch updater app and App store purchases still not showing. Thanks all
@dosdude1 @ASentientBot OK with the final MacOS 10.15 Catalina update on Macmini mid 2010 (macmini4,1) I don't know how exactly works, but I have found APFS defrag disabled on my external USB 3.0 Samsung drive and I have enabled it. Now the CPU use 100% only when starting a task, but then goes rapidly down to 30/40%, and my 10 year old Macmini is still usable.
Example:
diskutil list
/dev/disk2 (synthesized):
#: TYPE NAME SIZE IDENTIFIER
0: APFS Container Scheme - +680.5 GB disk2
Physical Store disk1s3
1: APFS Volume Macintosh HD - Dati 28.8 GB disk2s1
2: APFS Volume Preboot 83.9 MB disk2s2
3: APFS Volume Recovery 710.1 MB disk2s3
4: APFS Volume VM 1.1 MB disk2s4
5: APFS Volume macOS 10.15 Catalina 10.9 GB disk2s5
APFS defragment /dev/disk2s1 status
APFS Volume defragmentation is currently disabled for disk2s1
diskutil apfs defragment disk2 enable
diskutil apfs defragment disk2s1 status
Some minor bugs to fix:
1) Wifi icon on menu bar is greyed before i click on it, but then becomes white and Wifi works fine.
2) Caps Lock, Num Lock and Scroll Lock leds do not light on 2 wired PC italian keyboards. Workaround: CAPTIN utility to show actual caps lock status.
3) <> \| inverted keys on Italian PC keyboard. Workaround: karabiner-elements utility to detect the right keyboard type, then removed the utility.
Thank you again and again for your much appreciated help to the Macrumors community !!! Alex
