Wipe-clean Ubuntu installation

cn flag
hal

I recently bought a Thinkpad carbon X1 gen9 with Ubuntu preinstalled. The preinstalled Ubuntu have some problems (see this forum) and I was thinking of trying Debian.

As soon as I try to boot from the USB stick that has an image of Debian I am "thrown" into grub and I am unable to do anything else (I guess lack of knowledge).

Now, I thought that I try another distro, and tried to boot up Kubuntu. The result was that Kubuntu never loaded and something like a recovery mode of Ubuntu was triggered, resulting into a fresh Ubuntu installation. (see also this post where the same happened)

I have the feeling that this is related to some configuration from Ubuntu/Lenovo, triggering a recovery mode. As [this post] suggests, completely deleting Ubuntu did the job for him/her, so I was wondering how I can format from an Ubuntu installation.

Thank you

Are you actually booting those various USB installers successfully? It's hard to tell from your description. A successful boot of a Debian installer should give you a Debian screen with a big Debian logo and Debian install options. If not, then seems like a How-do-I-select-boot-device-in-BIOS question that's not related to Ubuntu. Ubuntu does not muck around with your BIOS boot selection options.

Yes I am. I have done successfully this procedure multiple times, on multiple machines. I was actually in doubt in the beginning whether the Debian installer was properly burned, that's why I tried Kubuntu (more straightforward). The fact that Kubuntu also fails to boot signals that it's not a USB stick/boot image problem.

Can you add a picture of the "*something like recovery mode*" ?

It's not a specific screen or something. What happens (e.g. when I try to boot Kubuntu) is that the Ubuntu are reinstalling. I am not getting an option for installing Kubuntu. Even if I try to boot another image with Ubuntu OS, I am also not getting an option to wipe-clean and install Ubuntu, it goes straight installing Ubuntu with the oem kernel, which is used in the preinstalled version in Thinkpads.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
