Ubuntu 18.04 suddenly stopped booting

Damsel in distress asks for help.

I cannot finish writing my master thesis because after a few years Lenovo G505 Type 20240 (single-boot Ubuntu 18.04.5 LTS) suddenly stopped booting. The screen is black with „Booting in insecure mode” and I cannot get to purple screen or desktop.

SMART and MEMTEST showed that HDD and RAM are OK. Neither changing BIOS settings nor resetting CMOS by removing battery helped. Pressing Shift or Esc did not work. I have managed to boot in live mode from USB (Ubuntu 20.04.2.0 LTS) and Boot-Repair was unsuccessful. Boot-Repair wanted me to delete unused files because partition was full (well, it was not) and I did but there was no way to empty trash folder.

„sudo fsck dev/sda2” results in „CLEAN, 267742/61022208 files, 229224017/244059136 blocks”

Live mode enables me to copy important files (e.g. Zotero) and in the worst case scenario I can move to another computer or try to format Lenovo and reinstall Ubuntu or other OS, but I would prefer to finish writing on this laptop.

I would really appreciate your help.

I wish you all good health!

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.
