Linux Lite Forums

I installed Linux Lite 6.6 on the hard disk (there is only one system on the disk and in the PC). Unfortunately, when trying to boot, the error "XE-E53: No boot filename received" appears, I have to select the boot source every time - the disk, which is set as bootable in the BIOS anyway.

With the information provided I suggest running the install again.
Check the Help manual for information on the BIOS/UEFI settings to use for Secure Boot and boot order.
