what is the first boot entry in your BIOS ?

[hasty radish]

show your BIOS boot category

if this is a legacy-BIOS computer (pre-2014) then boot the live usb again. use gparted to manage flags on the partition of your hdd currently having an esp and boot flag. take them two off, and put first the bls_boot flag, then the boot flag.

Either the installation failed silently, or your BIOS boot order isn't correct

Did you follow any advice here and solve it?
