Moderators Jake Lo Posted December 7, 2020 Moderators Share Posted December 7, 2020 From the 1st image, you'll see the view, there's an arrow for drop down option. Click on that and select View all devices. Now you should see model of the internal drive. Select that and you should be able to format it to GUID / Journal Extended. FYI, this will wipe your drive completely. If you have Windows installed, it'll be gone. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 7, 2020 Administrators Share Posted December 7, 2020 @Jorge1964, you need to understand that installing Big Sur requires something like 3 or 4 phases: you boot your USB installer, prepare your target disk/partition in Disk Utility (scheme + format) and complete 1st installation phase where all packages get copied to the target disk 1st reboot of the target partition (not the USB installer) where Big Sur packages will get properly installed on the target disk/partition 2nd reboot where the Big Sur installation completes 3rd reboot that gets you to the completed Big Sur installation and 1st boot system finalisation (setting of language/keyboard/user account/etc.) As JakeLo mentioned, it looks like you never went past phase #1...

Moderators Jake Lo Posted December 8, 2020 Moderators Share Posted December 8, 2020 Might be issue with your installer. Reformat it and create it again. Make sure to do the same - GUID / Journal extended. Then use createinstallmedia to create the installer Mount EFI and post the EFI folder Link to comment Share on other sites More sharing options...
Jorge1964 Posted December 8, 2020 Author Share Posted December 8, 2020 As you can see the partition map is GUID and the format is Expanded(with journaling), so it must be another problem. now I get this error message the system keeps rebooting in cycle, showing this screen Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 9, 2020 Moderators Share Posted December 9, 2020 This might be a compatibility issue with the QVO drive. See here Try replacing with a different Sata SSD or a known compatible NVMe drive. Samsung NVMe PM981 and PM991 are known to not work on MacOS.
