I have created a thumb drive with High Sierra Installer. I erased my internal High Sierra drive after booting into recovery mode/DU/Erase/format as APFS. I then went to intall MacOS and saw it was installing High Sierra beta so I cancelled. I then tried to reboot to select the thumb drive as the boot drive. Now I am pretty much stuck with internet recovery mode that wants to install Lion. Am I screwed at this point with having to install Lion and doing this over again? --- Post Merged, Mar 28, 2018 --- When I boot to the thumb drive with the installer, I get the Apple logo and a progress bar but then it goes to the dreaded circle/slash. I used Disk creator to create the installer.
