[SOLVED] I cannot get this to work - I am getting Critical errors

[bearhntr]

I used the same process as here: https://i12bretro.github.io/tutorials/0607.html

To build a completely new Flash drive - and then followed your steps to make it 'Monterey'. I know I should not have assumed, but your steps do not state otherwise. 😥 Should I be doing something else? I either get some kind of 'critical error' on boot - or I get to the "Reinstall macOS Monterey" option and am told "Installation could not continue. Installation requires downloading important content. That content can't be downloaded at this time. Try again later" -- I have verified I have Internet access.

I have a Desktop Optiplex 7010 and would love to put Monterey on it, as Big Sur is kinda old. I take it that Sonoma will not work?

I have discovered that you cannot use the entire disk when you install the Big Sur per the link above. This computer has a 240GB SSD and if I try and use full disk it gets to a point and just reboots over and over and over - never installs completely. If I adjust the partition when I erase the disk to only be 200GB I have no issues. I also discovered you cannot adjust this after installation (or at least I could not).

I figured out how to save the INSTALLER.LOG - no idea what any of it means (attaching here).
