How to come back to Cinnamon 19.1 - 20 is not stable at all for my machine

[Paolo1969]

Dear Forum, I instaled Debian & Ulyssa 20 versions but no one is stable in my machine, I would like to go back but installing with a 1 Tera HD portable drive (Samsung) I decided to create partitions and now I am a bit lost in how to proceed. Could anyone help?
The screen is sayng:
[2.972406] sd 2:0:0:0 [sdb] No Catching mode page found
[2.972445] sd 2:0:0;0 [sdb] Assuming drive cache: write through

BusyBox v1.30.1 (Ubuntu 1:1.30.1-4ubuntu6.3) built-in shell (ash)

Thanks,

Paolo

When you say LM20 isn't stable on your machine, please describe exactly what you mean. It may be easier to fix than to reinstall LM19. Looking at your inxi output, it appears your graphics driver isn't loading properly. Is that the only problem?

[Paolo1969]

The problem is that each time I turn my computer off I never know if I would be able to work on it the next day, it always says:

Code: Select all

Checking Media Presence.....
Media Present.....
Start PXE over IPv4.
Then PXE-E18 (something) and appears the options between 

Cinnamon
Ulyssa
some other

when I choose most of the time return to BusyBox, v1.30.1 (Ubuntu 1:1.30.1-4ubuntu6.3) buit in shell (ash)
Enter help
(initramfs)

What can I do to avoid that?

[mikeflan]

Maybe disable PXE boot in the bios:
