PC does not start after 'autoremove' and 'do-release-upgrade'

cd flag

I made an attempt to upgrade from 18.04 to 22.04 following the steps on [this site][1] https://blog.eldernode.com/upgrade-ubuntu-18-04-to-22-04/. At the step "do-release-upgrade" the system asked me to reboot first, which I did. However, the PC is completely not responding anymore. When I start it I don't get the bios splash screen nor the grub (?) menu where I normally can choose the operating system (I have dual boot). Also I can't enter the bios menu. All I get is a black screen.

Any help is much appreciated.

Upgrades from 18.04 are only available to the next release (18.10 but that [ceased being an option when 18.10 reached EOL](https://fridge.ubuntu.com/2019/07/19/ubuntu-18-10-cosmic-cuttlefish-end-of-life-reached-on-july-18-2019/)), or to the next LTS which is Ubuntu 20.04 LTS. I opened that link you provided and it looks like a bad *hack* to me, not written but I suspect the author grabbed a prior article & replaced some details but not others. I'd not have used it given the incorrect details within it. I'd suggest using *official* Ubuntu guides in future as you've chosen an *unsupported* path

If you don't get the BIOS splash screen, then you have a motherboard fault unrelated to Ubuntu or your release-upgrade.

Such faults are not caused by Ubuntu, nor by the process of a release-upgrade. Coincidence. It happens.

Ubuntu cannot repair nor compensate for hardware faults. You must repair (or replace) your hardware before you can do anything else with that system.

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.
