Make the following changes in the EFI setup application:
EFI Config Option	Value
Secure Boot 	Disabled
Linux Boot 	Enabled
Use pmbootstrap to build your own installation image (choose lenovo as the vendor and yoga-c630 as the device).
$ pmbootstrap init
$ pmbootstrap install --fde
The most straight forward way to install pmOS to the internal UFS storage (at least until ondev2), is to build a USB drive with a pmOS install, boot it, then use pmbootstrap to build/flash an image to the nvme disk. The process looks something like this:
# coreutils is optional, just for full fat dd with progress support
$ pmbootstrap install --disk /dev/<usb disk> --add pmbootstrap,gptfdisk,coreutils
# Boot the usb disk on the laptop
$ pmbootstrap init
# Figure out which storage device has your EFI partition on it, it should be the biggest and also contains windows.
# It's usually /dev/sda or /dev/sdf. Look for "EFI System Partition" in the output
$ sudo blkid
# Getting this wrong could leave your device hard bricked... Replace /dev/sdX with the correct device.
$ pmbootstrap install --sdcard /dev/sdX 
# Now make sure the ESP bit is set
$ sudo gdisk /dev/sdX

=== Manual partitioning ===
For manual flashing (e.g. to dual boot with windows or another distro) the following serves as a reference, but NOT a guide (you probably don't want to nuke the drive if you plan to keep windows).
$ sudo gdisk -l /dev/sdf
# Check that /dev/sdf is definitely the device with windows on, it should be the biggest and have an EFI system partition. If not then work out which device is.
$ sudo gdisk /dev/sdf
# Delete the entire partition table (your windows install will be gone)
Command (? for help): o
This option deletes all partitions and creates a new protective MBR.
Proceed? (Y/N): y
# Then create a brand new ESP
Command (? for help): n

== Known issues ==
Display initialization is quite quirky and occasionally doesn't work. The GPU and display stack in general can be quite fragile, although once it's running it usually doesn't fall over.
== See also ==
Support for the device isn't merged yet, so thinks links won't work.
