Installation

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 EFS 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

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.
