vinnytwice Posted May 24, 2020 Share Posted May 24, 2020 (edited) I'm struggling to install Catalina as I always get back to the 15 min remaining time .. screen after rebootingI first tried installing it on a separate volume on the same ssd where I have High-Sierra installed and installation loop made me think it was due to that, so I erased it to only have Catalina on, but nothing changed.The installation sequence is this: Start installation from downloaded installer. Remaining time progress bar goes down until 1st reboots happens @ 2 minutes left. On reboot ssd name changed into Boot macOSInstall from Catalina.Select it and the installation process starts with the 13 minutes remaining time.. progress bar and continues until 2nd reboot happens.Now Boot macOSInstall from Catalina changes into Boot macOSInstall from Catalina-Data.Selecting it starts installation loop, as it goes back to the 13 minutes remaining time.. progress bar and continues until it reboots again. Still ssd is named Boot macOSInstall from Catalina-Data. My motherboard is a Asus P6T Deluxe v2 and my graphic card is a Sapphire rx-580.What can I check to find out why is happening ?Thank you very much Edited May 25, 2020 by vinnytwice Link to comment https://www.insanelymac.com/forum/topic/343951-installation-loop-it-always-starts-from-the-15-min-remaining-time-screen-after-rebooting/ Share on other sites More sharing options...

Thanks. @Cyberdevs Indeed, I was initially saying in the question that I tried both that one method and installing directly from downloaded installer with same installing loop result , then realized that I couldn't discuss hat method here so I deleted a few lines but I jumped one.. Sorry for the hassle. I looked in my profile to update mi signature but I couldn't see any place for it. I'll look better. Thanks for pointing out both things.
