Hi Cindy-Sue
If you're using LILO you are _REALLY_ on your own since LILO is not
maintained any more. IMHO, you really, really need to convert to grub somehow
Where possible, I suggest moving to UEFI boot and grub in all cases when
installing Debian.. "Legacy" [MBR] boot is going away and GPT disks are
standard for larger disks. It doesn't work for all machines - I've an HP
Microserver that will live on legacy MBR forever - but for most things built
in the last 5-10 years there's an option to use UEFI.
All the very best
