MX-21 beta 1 is a "no-go" for me.
I downloaded the ISO, confirmed a good download with .sha256 file and made a Live Flash Drive using MX Live USB Maker in the "Full-featured mode...".
I booted up the MX-21 beta 1 Live USB Flash Drive just fine in UEFI mode with CSM disabled.
I ran the installer (21.7.04) and the installation failed at the "Installing GRUB" 95% point with the error "GRUB installation failed. You can reboot to the live medium and use the GRUB Rescue menu to repair the installation". That cannot be done because the installation does not finish - clicking "OK" on the error message simply returns the installer to the beginning of the installation process, aborting the installation.
This is almost the identical problem I detailed in my Post #3
viewtopic.php?p=644796#p644796 "GRUB does not install in EFI with CSM enabled in the BIOS" (dated 19 July 2021) but with a twist - the thread I created was about the problem that occurred ONLY with CSM enabled; with CSM disabled (pure UEFI mode) the installation completed error free and without any problems.
I said it is "almost" the identical problem because now, MX-21 will not install in UEFI mode regardless of CSM being enabled or disabled. The same error message at 95% as detailed in the above link results, so installing in UEFI mode is not an option.
However, I am able to install MX-21 beta 1 in Legacy (BIOS) mode with CSM enabled, of course.
It is interesting to note that MX-21 beta 1 is using mx-installer 21.7.04 that fails to install in UEFI mode while MX-19.4 successfully installs in UEFI mode (with CSM disabled) using mx-installer 21.7.02.
Attached is the minstall.log as copied from the MX-21 beta 1 Live Flash Drive. The error occurs at the same point as identified in the above link, this time on line 550 which is shown in the below code window.
