Notes

Entering system/boot menu

Keep pressing F1 (system settings) or F12 (select boot device) during startup while the screen is still black. By the time the colorful Lenovo picture appears, you're already in the Windows-10 boot process.

Installation

I did not attempt to set this up as dual-boot. However, before wiping the Windows OS, I did install a BIOS/UEFI update via Windows, which you can get from the Lenovo website.

I installed Ubuntu 18.10 with full disk encryption and secure boot. This went fairly smoothly compared to a few years ago, when extensive fiddling with UEFI settings was necessary. You'll be asked to define a one-time password to authorize the changes in boot loader; after reboot, the Lenovo firmware will ask for this password.

The default swap space was rather small, not enough for hibernation. I did manage to resize the partitions after installation (this is rather involved, especially with full-disk encryption), but Ubuntu didn't provide access to a hibernation function even with a 12 GB swap space.

Wifi

Unfortunately, no Wifi in Ubuntu 18.10. I did not spend a lot of effort to get this to work.
