My mid-2011 mac has two apfs volumes with high sierra installed on both for dual-boot, just in case... So I was using the "primary" volume and had been using OCLP to upgrade the os and just recently I accidentally upgraded to an unsupported os. So basically the primary os is near unusable.
Fortunately, I can still boot to the secondary volume which still has high sierra installed. I don't want to work off the secondary partition so I want to get the primary volume back to a working state. While running the os from the secondary volume, can I simply download the high sierra installer, and install the os to the primary volume (I think the primary volume needs to be wiped in the process)? Or do I still need to create a usb installer and boot to recovery to perform the install?
