I've been trying to install HS on my E6220, using this guide.
But I can't get the install process to work. After creating the USB installer and booting up, the Clover Screen loads fine. Then I choose the "Install High Sierra" option with -v flag. Then it goes through all the commands and suddenly reboots, prompting the message "attempted to boot uefi volume from legacy mode" and going no further...
Do you have any leads what to do?
I've tried several times to create USB-installers, both with Clover r4689 and r5097 (with the latter, using the customized settings from the E6220 Mojave guide)
