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?
Thank you all very much for your replies and help. Removing the disk and battery helped, the laptop turned on to UEFI settings. But does anyone have an idea how to solve this bootloop with Ubuntu now? Fresh system and partitioning through the default settings of the ubuntu 25.04 installer. When I turn it on this message appears for a few seconds and then the computer resets. One tutorial on the internet told me to turn on secure boot but as you can see from my first post it didn’t do anything.
Solved. I found a boot-repair tool. Run it from live CD and it repaired my ubuntu installation. Thanks for answers and help!
