I have tried several times to create an USB boot disk (Ubuntu) using the description in the Chuwi user group tutorial section. When I try to boot the HI13 from the USB disk I end up with a blank, black screen and a single “_” character  in the upper left corner. The bios is updated to the latest version.   Are others having the same problem?

So far TechTablets guy is the only 3rd party that tested Ubuntu with good results (yet needing scaling) on the Hi13. But I don't remember how much details in that regard, he went into in his first video. He didn't go into many details in that regard as far as I remember.  But he might offer a clue?
Edit: clarity + typo.

Hi

I was able to first boot into arch linux using refind bootloader. After that I played a little bit with RemixOS image, replaced grub with refind and was able to boot RemixOS. Actually it is not usable - I can see only first configuration screen, touchscreen doesn't work, touchpad very slow.

I guess that ubuntu and other linux distribs use grub and it doesn't work on Hi13 (I suspect that it sets some video settings which do not fit Hi13 and stuck on that step)

Thanks for your input. It would be nice if Chuwi could tell us how Ubuntu should be implemented on the Hi-13. A tutorial or something would be nice...

The SurBook is also advertised as supporting Ubuntu, so something has to be on the way to clarify how to replace Windows completely, or if it's possible to go dual boot without any negative side effects, with the exception of splitting the already limited storage. I don't understand that, it's just not practical (Edit: from my viewpoint). Just choose an OS, and stick with it until you have enough good reasons to switch.

Edit: also OP started and focussed on external Ubuntu over USB, not on internal emmc. So not sure what feedback he got from TechTablets forum.

So what was the feedback? Since he did get it working over USB according to what Hackerjac understood from the vid as well.

Short "how to" make bootable disk for your distributive (made that for Arch, RemixOS and Android-IA, with some changes applicable for other distros)

prerequest: you need Linux installed somewhere else and downloaded iso

1. Put flashdrive into your linux box (assuming it is formatted with fat32 filesystem) and mount it: sudo mount /dev/sdx1 /mnt/flash
2. Install refind-efi package (can be just refind - check with your distro documentation). For arch: sudo pacman -S refind-efi
3. Mount your distro iso to somewhrere: sudo mount -o loop /path/to/file.iso /mnt/distro
4. Copy files from iso to flash: cp -r /mnt/distro/* /mnt/flash
5. Replace grub bootloader with refind:
  • rm -rf /mnt/flash/efi
  • mkdir -p /mnt/flash/efi/boot
  • cp /usr/share/refind/refind_x64.efi /mnt/flash/efi/boot/bootx64.efi
  • cp /usr/share/refind/refind.conf-sample /mnt/flash/efi/boot/refind.conf
6. Now comes some hard stuff - you need to configure refind according old grub config and flashdrive U
  • lsblk -f - find here UUID for your flashdrive (967F-722C in my case)
  • vim /mnt/distro/boot/grub/grub.conf - find here menuentry with kernel and initrd, eg:

menuentry 'ANDROID-IA Live Boot (2017-04-23)' --class android-ia {
        linux /kernel enforcing=0 androidboot.selinux=permissive vga=current i915.modeset=1 drm.atomic=1 i915.nuclear_pageflip=1 drm.vblankoffdelay=1 i915.fastboot=1 root=/dev/ram0 androidboot.hardware=androidia_64 androidboot.selinux=permissive firmware_class.path=/vendor/firmware iTCO_wdt.force_no_reboot=1 buildvariant=eng LIVE=1 quiet
        initrd /initrd.img
}


  • vim /mnt/flash/efi/boot/refind.conf - go to the bottom of the file and add:


menuentry "ANDROID-IA Live Boot kernel 4.9" {
    volume 967F-722C
    loader kernel
    initrd initrd.img
    options "enforcing=0 androidboot.selinux=permissive vga=current i915.modeset=1 drm.atomic=1 i915.nuclear_pageflip=1 drm.vblankoffdelay=1 i915.fastboot=1 root=/dev/ram0 androidboot.hardware=androidia_64 androidboot.selinux=permissive firmware_class.path=/vendor/firmware iTCO_wdt.force_no_reboot=1 buildvariant=eng LIVE=1 "
}


7. unmount the flashdrive and try to boot into (press f12 to get into boot menu)

that's it!
