Did I just bricked my laptop? I reinstalled ubuntu but after rebooting it would fall into bootloop with a "reset system" message. In the tutorial I read that sometimes it helps to enable secure boot, well I did that but now I can't get into BIOS/UEFI at all. Laptop: lenovo thinkpad x1 carbon 3rd Anyone could help somehow?
Press Enter.
I see from your photo that it's a Lenovo - pressing Enter to interrupt normal startup will give you a menu which then lets you get into the BIOS.
If it doesn't go past the "press Enter" point you might need to remove the HDD (or whatever storage it has) and try again. Reconnect once you've changed the settings back.
