I have just installed Debian on a new HP Proliant 310e V2 Gen 8 server. I have been installing Linux on desktops, laptops, servers (only Dell) for over 15 years. I know my way around multiple Linux distros, but prefer apt-based systems, especially Debian Stable for servers.
I converted the entire partition into a physical area for encryption, followed by LVM, and partitioning into /, /tmp, /var, /home and swap. The install was unremarkable but I could not install grub to MBR.
I have a mystery partition (about 256 MB in size) that was untouched during the install. I assume it contains all the extra software that HP has preloaded (like Intelligent Provisioning, etc.).
How do I boot into my install?
