<< Solved >> Problems creating boot disk

[grandebeast]

Hi,

First off, I have PC hardware that is compatible with Catalina.

The Mac I’m using to create my bootable USB stick, is running Sierra and is a 2011 iMac.

I couldn’t download Catalina on it, so I used a recent MacBook to do that.
I then copied the Catalina install file across to an Ex-Fat USB stick, then onto the Sierra Mac.

All okay so far.

I then followed the instructions here to download UniBeast and went through the steps to create my boot ‘disk’.
Unfortunately, for some reason, I could not select Catalina in Unibeast, so I gave up on that.

I then realised that my iMac already had a High Sierra install file (downloaded it at some point and then forgot), so I downloaded the UniBeast file for High Sierra, and started the process again, to try and create my bootable USB stick.
It appeared to be running, however, after about 20 minutes, it failed. I didn’t get a screen shot of the error message.

When I checked the USB stick, it looks like something is there, taking up 5+GB of space, but I’m not confident that it will boot into my PC.

I’m going to try it and see what happens, but can anyone advise why I couldn’t create a Catalina boot disk?
Also, what did I do wrong with High Sierra???
Does the macOS version of the bootdisk you’re creating, need to match the OS version of the Mac you’re creating it on?!
Is there something obviously wrong with what I’ve done?

Thanks!

Anyone got any ideas what I’ve done wrong, or does it sound okay?

I installed my M.2 SSD; had to remove the motherboard from my PC, as the socket is on the reverse side of the motherboard.

Booted up from my USB stick and had a promising start.
It started booting MacOS, I selected my language, then I got to utilities, in order to format by SSD.
However, when Clover started up and I selected to boot High Sierra, the following warning was displayed:

Here’s what I saw in disk utilities.
I’m not clear on whether or not my USB device should have 2 partitions, as there appears to be.
It was brand new when I created the High Sierra install.
Is that why I’m getting the warning?

Anyone know what I need to do?

I consider this to be resolved, as I managed to get macOS installed; kind of.
I’ll create a new thread for the issues I have with the installation.
