I got a Chromebook (just a couple of months ago) with the specs below and I'd like to boot off a USB flash drive (which I have yet to create) so I can use Linux every once in a while.

The software I want to use requires Linux, of course, graphics like KDE, and Tcl/Tk. The USB drive I'm going to put it on is 128GB. My favorite distro is Slackware. I want the type of setup that allows to pick up where I left off last time and not start fresh every single time I plug in the drive.

I have to create a USB Linux drive on my Chrome OS 'cause I don't have access to a Windows machine right now.

How do I go about doing that? What else do I have to do apart from getting the .iso file?

Developer mode isn't enable yet so if you're going to give me instructions include that as well.

How difficult is this going to be on a Chromebook?

Acer Chromebook R 11 Convertible, 11.6-Inch HD Touch, Intel Celeron N3150, 4GB DDR3L, 32GB, Chrome, CB5-132T-C1LK

Only "live cd's" don't save changes. I don't have any experience with chromebooks so I can't say as to the degree of difficulty, but I would think it shouldn't be difficult.

As far as the best way to do it I would go with the Slackware installation instructions

Read and do the links in order.

Do you have an Android phone? Maybe you can use the phone as a bootable USB, and then use that for the Slackware installer image. So, you boot up with the phone attached to one USB port and your thumbdrive in the other USB port. Then, you install onto the USB thumbdrive just like a normal hard drive install. Linux installers see a USB thumbdrive just like any hard drive.

Note - I'm not super familiar with Slackware installer iso images. I think most, if not all, major linux distributions now use iso images which will work both as a CD/DVD image or as a USB thumbdrive image.

You'll still need to activate developer mode in your Chromebook in order to get the option to boot from USB.

That's a great idea IK and I do have an android phone, as a matter fact.

Where would the .iso file be?

You are right about the Slackware .iso images.

Honestly I've never done it - it's just something I found when I googled up how to make a bootable USB drive using Android.

This how-to is from 2013, but hopefully it still works the same:

The linked Android App, DriveDroid, is still available. I think you can ignore whatever the heck all that Rufus is, as I think it's specific for converting Windows install discs to bootable USB or something.

As for where to download the iso file from, well honestly I don't know for Slackware. If it were me, I'd be installing Debian with Debian's small netinst iso. But then, I don't even know how much free space you've got on your Android phone.

I use DriveDroid all the time it's an awesome app
