I recently got Mojave installed but decided Catalina would be more future-proof for what I need, so I created a USB installer using the same method as for Mojave (using a VM to download and transfer the installer) and then I copied the working Mojave EFI folder to it.
I then performed the additional steps for a Catalina install as per steps 4 & 5 here (generate DSDT table and EC spoofing):

https://hackintosher.com/guides/guide-to-fresh-installing-macos-catalina-on-a-hackintosh/

At first it looked like it was going to work first try, but it got stuck at the white Apple logo after the 2nd restart. I've tried it a few times and it always gets to exactly the same point on the progress bar ("About 11 minutes remaining"), then there's one last flash of the SSD read/write indicator, then it just stays there.
Something similar happened on my Mojave install but if I left that for around 6 hours, it would eventually install and if I checked on it in the meantime I'd see the occasional SSD read/write light and the progress bar would slowly creep up. However with this Catalina install I can leave it for 24 hours and the progress bar doesn't move a millimetre.

Given that Mojave sort of got stuck and this is now getting stuck, I presume that there's something wrong with my config (attached).
Could anyone take a look? Or does anyone have any other ideas for what I can try?

I'm using:
Intel Core i5 2500k
ASUS P8Z68-V LE
Onboard Intel HD3000 graphics (I've got an Nvidia GPU but it's not installed while I try to get this working).

I've deleted Rt Variables > MLB and SMBIOS > Board Serial Number, System Serial Number and SMUUID from the attached version of config.plist but apart from that it's all identical to what's on my USB installer.

The Intel HD 3000 IGPU is not supported in Catalina, as it lacks Metal2 support, which Apple implemented as a system requirement, when they released Catalina.

The oldest Intel IGPU supported by Catalina is the HD 4000, which comes with the higher end i7 Ivy Bridge CPU's. You may be better served disabling the HD 3000 IGPU in your bios and just rely on a compatible dGPU for graphics work if you plan to stick with macOS Catalina.

Your Nvidia GTX 750 Ti is not a natively supported dGPU, when it comes to running Mojave or Catalina. It is a Maxwell series card, according to techpower up site - https://www.techpowerup.com/gpu-specs/geforce-gtx-750-ti.c2548, not a Kepler series card, most of which are still natively supported in Mojave and Catalina. See this Catalin Buyer's guide page regarding Nvidia dGPU's - https://dortania.github.io/GPU-Buyers-Guide/modern-gpus/nvidia-gpu.html

You need to revert back to macOS High Sierra, and installe the Nvidia Web Drivers to get your HD3000 and GTX 750 Ti working in macOS.

Alternatively, disable the HD 3000 in the bios and install a compatible AMD or Nvidia (Kepler series) dGPU.

It looks like the HD3000 graphics got patched for both Mojave and Catalina a few weeks ago:

https://github.com/chris1111/Legacy-Video-patch/blob/master/README.md

I've seen people posting screenshots to verify it's working.
Also the instructions for running the patch stipulate that it be done after Catalina is installed, so I thought that meant it was possible to at least finish the installation with HD3000 even if the graphics looked terrible.

I installed Mojave ok on this same machine, it just looked horrible with a really low resolution.

That is not native support for the HD3000. It is a post installation Hack, you will have very poor graphics during installation, i.e. no acceleration QI/CE, until the Hack is applied.

MacOS Catalina may stall during the installation due to the unsupported IGPU. You may be best served borrowing a compatible dGPU for the installation and until the Legacy Intel fix can be applied.

Yeah graphics during the installation are like they're from 1995! It was the same for Mojave. I didn't care as long as it installed and then I could fix it later, but if it's stopping the installation then obviously that's a big problem. Maybe I should just buy another (Kepler series) GPU as I can then use it with macOS and Windows as well.

So am I right in thinking that if I get the correct one, I'll be able to get normal graphics even during the installation with the right kexts in Clover? It will just work right from the start?

Do you know of any Kepler series GPUs that would be the equivalant in performance of my GTX 750 Ti? I was very happy with it for my needs so there's no point in me spending more money than I have to. Something the same or slightly better would be fine for what I need.

Have a look at the buyers guide linked in post #2, it lists all the supported Kepler dGPU's. Although not many of the Nvidia cards will still be available, and even less will be available new. You are probably best looking at an eBay purchase for a second-hand Kepler card.

The GTX 760 would be equal to or jsut slilightly better than your GTX 750 Ti. The GTX 780 & GTX 780 Ti would provide a significant improvement over the GTX 750 Ti, but I don't think any of these three cards would be cheap, even second hand.

Here is a benchmark comparison between the GTX 760 and your GTX 750 Ti - https://gpu.userbenchmark.com/Compare/Nvidia-GTX-760-vs-Nvidia-GTX-750-Ti/2159vs2187.

The other two cards are much more powerful than the GXT 760, with the resulting benchmark for the GTX 780 Ti being close to double the GTX 750 Ti. Here is a comparison of the GTX 780 Ti and GTX 750 Ti - https://gpu.userbenchmark.com/Compare/Nvidia-GTX-780-Ti-vs-Nvidia-GTX-750-Ti/2165vs2187

Alternatively, you could look at switching to one of the AMD RX 400 or 500 series cards. See this page for supported AMD dGPU's - https://dortania.github.io/GPU-Buyers-Guide/modern-gpus/amd-gpu.html. The RX 480, RX 570 and RX 580 are all still very good performing cards and will still have a bit of future proofing.

The AMD RX 560 would be a lower end choice as it would provide only a slight improvement over your GTX 750 Ti, according to this Benchmark comparison - https://gpu.userbenchmark.com/Compare/AMD-RX-560-vs-Nvidia-GTX-750-Ti/3926vs2187.

Do not buy a GPU from China on eBay, as it is just as likely to be a fake. Personally I would steer clear of XFX cards, but that is just a personal preference of mine.
