Hi, I hope I've selected the right place to place my questions, I'm not very good with French and English is not my main language, so... xD

I've got a CX CAS with OS 4.4.0.532 and I want to be able to install 2 Operating Systems on the same calculator.
I've been reading a lot of threads in this forum, and I'm aware of the nLaunchy, nBoot and ControlX, I've found a guide to install a Ti OS and Linux, but I want to install 2 Ti OS.

If someone can help me with this I would do a video for the community with a step-by-step guide, so the solution of my problem could help others too that are still noobs dealing with Ti software.

I know that I could try the Linux tutorial, but I really don't want to brick my CX CAS, that's why I'm asking your help to be sure that I'm doing the correct procedures.

Hi.

Which Operating Systems would you like to install ?
4.4 CAS and ... ?

Thanks.

Hi critor, it's the same OS.

Boot1: 4.4 CAS
Boot2: 4.4 CAS

Anyway, you can't have 2 TI-Nspire OS installed at the same time.

There are just more or less quick ways to switch your OS by installing another one.

So I can't really see the point in being able to switch from 4.4 CAS to 4.4 CAS.

Could you explain what you are trying to achieve ?

On test/exams we must clear the CX CAS memory completely, and on every test/exam, I must upload all of my programs, input all serials to activate 8 different programs (step-by-step programs), upload the documents to my PC before the memory reset...

So I would like to have:
Boot1: Clean OS
Boot2: All of my programs

Then on test/exam days I would just use the Boot1 and I wouldn't have to create backups and install all of my programs over and over again.

Ok.

How is the memory cleared for exams ?
Do you clear it yourself ?

Is the calculator then checked during the exam ? How ?

Thanks.

I clear it myself, I must delete every document in the "Documents" folder, then the teacher comes to my seat and checks if the Documents folder is empty and only then the test/exam starts.

Then you have a great official feature for this, it's the exam/test mode.
Turn the calculator off then hold while turning it back on to enable it.

In exam mode, the /documents content will be hidden.

After the test, you just have to disable the exam mode and you'll find back all your files.

Just pressing a button and the problem is solved, lol.

And what do I need to press to disable the exam mode?

You must send a specific file to the calculator.
