Boot failure after clean install

Installed 42.2 from USB DVD onto Acer notebook. Text only version. No errors occurred. But when I try to boot it tells me there is no bootable media. I can boot SuperGrub2 from a USB stick and start 42.2 but various attempts to update the bootloader had no effect. The following is information that’s available:-

I must have formatted the drive incorrectly. Any suggestions would appreciated.

Are you trying to boot in legacy mode? Your install is EFI boot

Also looks like you had ubuntu since yo have leftovers in EFI boot.

Can you use the EFI boot selector??

Maybe the UEFI is trying to boot Ubuntu

there is a common problem with some models of ACERs “supervisor password” and BIOS upgrades sometimes required. you can see some of the issues on this thread https://ubuntuforums.org/showthread.php?t=2291335&p=13341757#post13341757 you should give the exact model number, bios version. i dont believe installing mbr if it is eufi is a good idea.
