Yes you'll need to reset minOS, each time you want to switch

If you hot-switch to an older version and forget to reset minOS, the new OS is going to be removed on the next boot.

Okay, thank you all!

You're welcome.

hello,

I got the same error like frank.

Accessing the diag or maintenance menu doesn't work. Maintenance menu is not showing up at all and diag sometimes tells me, that there is no OS installed, or it brings up the grey screen with the clock (freezed) and then it reboots after a few seconds.

PS: It could be that I used old files from another tutorial <.< (Hope this helps you)

It doesn't make any sense, sorry.

But that's, whats happening

Totally impossible, sorry.

Maybe taking and sharing pictures would be a better idea.

Normal StartUp (+try to access maintenance menu ( )):


"Diag-Menu" ( ):


I couldn't manage to get the green screen with the clock. (I think, this happened, when I tried to reinstall the OS)

Ok, this looks clearer to me, thank you very much.

Well apparently, you flashed a wrong image in the Boot2 partition.

By using the Diags combo, you should be able to install an OS and then resume the tutorial at step D.
In this context, nLoader won't be enabled. So you need to install a non-CAS OS for now.
