So, I got my Lapbook Pro with Windows, but I as many other people was trying to start their Linux partition unsuccessfully and getting a black screen, we were changing options in Bios and if you choose the Linux OS option WILL BREAK the BIOS and brick your device (no usb, no nothing, no bios) after this your only option would be to buy a cheap CH341A programer and fix it (for us who can’t afford to send it back to guaranty), flash the BIOS and Ta-da! it works again, but you’re in the same situation, will be able to start only windows, so what to do?..
HERE’S THE TRICK:
The EFI partition isn’t being detected, what is detecting is a generic ubuntu/linux/etc? partition that is done from a previous installation before the grub installation and that option that is being displayed isn’t leading to any system so it shows a black screen with a little white line. What you have to do is this:
-
Download Manjaro KDE (I did it with this) burn it in any USB, chose the DD option.
-
Once there, at the bottom the last option has the booting options, once there you’ll be able to see your linux partition, chose it. IT WILL BOOT.
-
Once in your Linux system, open the terminal and execute this command: sudo grub-install
-
Then execute this: sudo update-grub.
-
Profit
Now when you restart your Lapbook Pro it should display the grub menu and that’s it.
*Info about flashing with ch341, the chip is the one that has a colored spot (in mine was a red spot) and remember the orientation of the red cable has to obey the black little spot in the corner of the chip, once in the software it should detect it as a GigaDevice 25q80 and it will be ready to flash.
Good luck!
