I'm pretty sure no-one subscribes to this blog, which means I'm free to post relatively obscure, relatively technical, articles that will probably save someone a day or two.

I've an Acer Travelmate B117-M, the version with a 64gig eMMC drive with Windows S, with a free option to upgrade to Windows 10 Professional.

I intended to, somehow, fit Windows 10 and Debian Linux into that 64 gigabyte drive ( using a vendor's method of calculating disk space in gigabytes, so actually nearer 58G of space ) and dual-boot between the two. But then I happened across this YouTube video about how to change the battery on the laptop:

Acer TravelMate B1 (B117-M-C4XR) notebook - How to remove battery

and from here I can see there's an 2.5" SSD sized space for the SSD version of this laptop, even though a thin "m2" format drive is shown on that video. As I had a spare 2.5 inch SSD drive I took off the back of the laptop I tried it, as it was 7.5mm thick it just fitted in nicely, and it was seen by the BIOS.

( note 9mm thick 2.5" drives are too thick, which I think elimates all standard hark disks and thicker SSD drives )

From here I could install Debian, but bear in mind with the B117-M, and the stable distribution of Debian, you will need to download the "iwlwifi" package separately to use the internal WiFi card.

Also bear in mind "unzip" isn't within Debian stable by default, so download the tar.gz file of the extra firmware for Debian.

At this point you might have to go into the BIOS, and disable the "Secure" option under UEFI, to boot the Debian install USB key you made and get the process started.

Once you've made an install key for Debian and installed the operating system, and rebooted... you'll find you can't boot Debian, and if you hit F12 your SSD won't come up in the options. They way to solve this is wonderfully counter-intuitive, basically follow the advice here: https://forum.siduction.org/index.php?topic=6272.0 , just the BIOS related advice from that article, point 5 onwards. So select Secure boot under UEFI, then go back to the Security options and find the efi file in your Debian install, select it, reboot back into the BIOS, disable the secure boot, reboot again, and then you should have Debian as an option. Making sure to save the BIOS settings every time you exit.

Bonus Material

From very limited testing, the device can be turned into a ChromeBook too, check out Arnold The Bat's website here. I recommend using one of the "special" builds rather than the "vanilla" build.
