Windows and Ubuntu Dual Boot on an x64 LattePanda

Introduction

This guide will walk you though how to dual boot Windows 10 and Ubuntu 16.04 LTS on a 4GB x64 LattePanda with Z8350 processor.

Note that at the time of writing driver support under Linux is limited, but essential features such as WiFi, Bluetooth, DSI, HDMI and Audio work well. You can find information in our Linux discussion on our official forum.

Step 1: Shrink your Windows 10 Partition

Boot in to Windows 10
Right click on the Windows 10 logo in the taskbar
Navigate to Disk Management
Right click on your Windows 10 partition C:/ and select Shrink Volume

Choose the shrink size you would like. This will become unallocated space on your drive that you can then use to install Ubuntu (or another Linux distribution). The amount of space will vary according to your needs. We allocated 15 GB (15000 MB).

Step 2: Make an Ubuntu 16.04 LTS Boot Disk

We have prepared a toolpack that has all the necessary files to create an Ubuntu boot disk.

You will also need to download the Ubuntu 16.0.4 LTS image

Burn the Ubuntu image to a USB drive (at least 4 GB). Our toolpack includes a utility to do this.
Insert your USB drive to a free USB port on the LattePanda, and reboot the machine. When the LattePanda boots, you will be greeted by the Ubuntu GRUB.
Select Install Ubuntu
Install the system on the unallocated space you created earlier. Click through all the default settings for now, you can install updates later.
When the system is installed, reboot the LattePanda.

At this stage it will boot in to Windows 10 by default, so we need to edit the boot manager settings.

Step 3: Edit Boot Manager Settings

Press the Windows Key on your keyboard, type cmd, and then right click the command prompt application
Click Run as administrator
Type the following command: bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
Hit enter and await confirmation
Reboot
When the LattePanda boots, you will be greeted by the Linux GRUB, which will enable you to select which operating system to boot in to

A this stage you have two operating systems, but you will need to do some tweaking to get all the hardware recognized by Ubuntu.

Step 4: Configuring WiFi/Bluetooth Drivers in Ubuntu

Download the Kernel Patch Kit and unzip it to a USB stick
Connect a USB keyboard and mouse to the LattePanda
Hit esc repeatedly on boot to get in to the BIOS
Navigate to: chipset > south bridge > LPSS & SCC configuration > SCC SDIO support
Change SCC SDIO support from ACPI Mode to PCI Mode
Press F4 to save settings and exit
Boot in to Ubuntu
Dump the file ubuntu16.04_patch_20170223.tar somewhere. In this example I stored it on the root of a USB stick that was mounted to the filesystem.
e.g.
cd /media/lattepanda/usbstick/
Open a terminal (Tip: ctrl+alt+t opens one in Ubuntu)
Run the following commands:
sudo su
cd /<stick/directory> (in my case this was /media/lattepanda/usbstick/)
unzip tar xf ubuntu16.04_patch.tar.gz
Tip: Hitting the tab key will auto-predict filenames to save you typing them all out
When it has unzipped successfully, navigate to the directory that it has created and run the provided install script (make sure you are running as root):
cd ubuntu.16.04_patch
bash ./install1210.sh
Wait for the process to complete.

Step 5: Edit `grub.cfg`

Still running as root, navigate to grub directory
cd /boot/grub/
Backup grub.cfg so you can revert back to it in case of any disasters
cp grub.cfg grub.cfg.old
Now you have a version to revert to if you run in to issues
Change the permissions of grub.cfg so you can read, write and execute the file
chmod 777 /boot/grub/grub.cfg
Edit grub.cfg using your favourite text editor. We used nano.
sudo nano /boot/grub/grub.cfg
Tip: In nano you can press ctrl + w and type part of the name to find matching entries
Search for the following section:
export linux_gfx_mode menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-3a08ec07-2677-499e-9638-aea4af1c9d0d' { recordfail load_video gfxmode $linux_gfx_mode insmod gzio if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi insmod part_gpt insmod ext2 if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root 3a08ec07-2677-499e-9638-aea4af1c9d0d else search --no-floppy --fs-uuid --set=root 3a08ec07-2677-499e-9638-aea4af1c9d0d fi linux /boot/vmlinuz-4.4.0-21-generic.efi.signed root=UUID=3a08ec07-2677-499e-9638-aea4af1c9d0d ro quiet splash $vt_handoff initrd /boot/initrd.img-4.4.0-21-generic }
Search for this line within the section:
vmlinuz-4.4.0-21-generic.efi.signed
Change it to:
vmlinuz-4.4.0-2017022104
Search for this line in the same section:
initrd.img-4.4.0-21-generic
Change it to:
initrd.img-4.4.0-2017022104
(Take note that UUIDs will vary for your system. Leave them as they are, they do not need to be changed).

!!Double check how you have named your files, or your system wont boot and you will have to run extra steps to restore it!!

Press ctrl X and then Y to save and exit, and then reboot

When the system boots again you should now have working WiFi and Bluetooth.

Troubleshooting

Boot Error

If you have an error in grub.cfg, the system will not be able to boot. You will need to revert to the grub.cfg.old file we made earlier.

Boot in to recovery mode
Navigate to /boot/grub/ cd /boot/grub/
Delete or rename grub.cfg and replace with the backup file you made earlier by running mv grub.cfg.old grub.cfg
Reboot by running reboot

You should now be able to boot Ubuntu, but you will need to repeat step 5 onwards.

Porting Linux to the LattePanda

Porting Linux to the LattePanda is an ongoing project and we welcome all feedback about your user experience using Linux. Under this version of Ubuntu we have the following working successfully:
