does not identify my macintosh HD
I am trying to update my 27" imac from 2017 from High Sierra to a more recent OS like Ventura. I can't get the OS to update because it thinks my Macintosh HD is a temporary storage device and IDK how to fix this situation....can't seem to get past the install page so long as this is the case. Any ideas of what to do?
iMac 27″ 5K, macOS 10.13
