OCLP 1.5.0 first timer issue

Hello All!

So I have a 2017 MacBook Air I’d love to update to Sonoma. I got through The 1.5.0 setup, the EFI Boot, ect.

I did a clean install, and selected the MAC HDD, it got though about 80% then went dark, and when it came back on it showed the folder with the question mark icon in the center of the screen. I tried multiple times double checking the set up instruction, and every time it shows the same question mark File icon.

Is there something I did wrong, it a work around?

Thanks in advance for any input!
