Ubuntu boots only one time after installation

hu flag

I just purchased a dell inspiron 14 7000. I installed ubuntu 20.04 on it but I have a problem: Everything works fine during installation. I can boot it one time after the installation. After that, if I reboot it, it doesn't boots anymore: black screen.

First of all here is what I have done to install it:

  • I put storage option from RAID to AHCI in the bios
  • Secure boot is ON
  • one EFI partition of 500 Mb mounted in /boot/efi
  • One EXT4 partition mounted in /
  • Ubuntu is my first boot option

Do you have an idea of where comes this problem from ? Why ubuntu boot only 1x after installation ?

Thanks in advance

Disable Secure Boot to start with.

Sometimes there a difference between 1. cold boot (shutdown, wait 10 seconds, boot) and 2. reboot because some cruft is surviving (and not cleared). - Please try cold boot. -- Next, please try Ubuntu 21.10, the newest version, it may work better in your computer --- Try also with the [boot option](http://ubuntuforums.org/showthread.php?t=2230389&p=13370808#post13370808) `nomodeset` (if there is nvidia graphics).

@sudodus Thank you for your suggestion. I tried with the boot option acpi=off, it worked. After downloading NVIDIA prioritary drivers it seems to work without disabling acpi.

@Poumon, I'm glad you found a solution and thanks for sharing it :-) Feel welcome to write an own answer (and I think after two days you can 'accept' it which helps other users find it).

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.
