I bought a new laptop E200HA, because my previous was a MacBook and It broke after a fall into the ground.

I let it boot first in Win10 to check if everything was OK and because I could not found the way to enter in the UEFI/BIOS. It is F2 and is edge triggered. It boots fast into Win10, but I got the feeling of being a little slow. No worries because I it bought for running Debian and because of the autonomy of the battery, 14hours playing music according to Asus. A little research if the new laptop could run Linux almost return no hits, but one very valuable link on how to setup the Wifi. So I got the feeling that I needed a Debian stretch CD for installation. So I download the first installation DVD from here. Run a trial of the DVD image using kvm

kvm -m 2047 -cdrom debian-stretch-DI-alpha7-amd64-DVD-1.iso

Found that the installer DVD now have the functionality of Live CD. This will be useful. Copy the image to a USB stick using dd command.

I turned on the E200HA, entered into the UEFI/BIOS by pressing and releasing the F2 key. Turned off the secure boot and select USB storage for boot. The E200HA happily boot the Linux and I select the rescue mode. Using another USB stick of 32GB that was formatted in xfs, because of the lower slack for storing the inodes than ext3/4. In this USB stick I put a raw image of the internal storage of the E200HA, preserving this way the Win10.

Another reboot, this time for installation of Debian stretch. It detected the lack of firmware files, for the WiFi adaptor. This link come very handy. The instructions are for an older Linux kernel. So I recommend doing something similar to the following commands:

git clone https://github.com/ajaybhatia/Qualcomm-Atheros-QCA9377-Wifi-Linux
cd Qualcomm-Atheros-QCA9377-Wifi-Linux/firmware-only
tar cvf QCA9377.tar QCA9377

Copy the tar file to a a second USB stick and connect it to the other USB port. This tar is not the files the Debian installer are expecting, so you need to change to the second console "Alt-F2", press enter to activate a shell, and do the following commands:

cd /lib/firmware
mkdir ath10k
mount /dev/sdb1 /mnt
cd ath10k
tar xf /mnt/QCA9377.tar

Return to the first console "Alt-F1" and continue with the installation. The list of missing firmware files is reduced and the WiFi can work. I had problems with the WiFI, but was because a neighbor router was on the same channel, since I changed the channel of my router the WiFi is working as a charm.
