Where did ubuntu go after bios update?

I just updated the bios in my Acer Swift SF314-57 (2019) from 1.07 to 1.18. The system has an original Win10home installation, a Win10Pro installation, (both of which I am trying to avoid using) and a Ubuntu 22.04 LTS installation (that I am trying to get used to using). I ran the update .exe file on the Win10home, then rebooted with shutdown /r /fw where I adjusted the following options to the way I believe they were before:

  • F12 boot menu = enabled
  • function key behavior = Fn
  • fast boot = disabled
  • secure boot = disabled
  • boot priority = 1. ubuntu 2. windows boot manager

I am presented with the same boot options as before; however, when I try to boot into ubuntu I get stuck at the Mate logo and in ubuntu recovery mode it gives up waiting for the root file system device. When I boot with my Gparted USB stick it does not see the hard drive and same if I boot from my ubuntu installation USB stick. Windows still runs fine.

What could be wrong?

Did it also reset trust? Acer has the "trust" issue. You have to turn Secure Boot on & enable "trust" on the Ubuntu entry. Then you can turn Secure Boot back off. If you have set a UEFI password never forget it or reset to blank.

I don't quite understand this comment. TPM is enabled, but I didn't encrypt the disk or anything like that. How does one enable "trust" on the ubuntu entry?

Older, but if trust is issue still applies: https://askubuntu.com/questions/597213/bootable-device-not-found-after-clean-install-of-ubuntu-14-04-uefi-on-acer & in step 35: http://askubuntu.com/questions/627416/acer-aspire-e15-will-not-dual-boot Acer Swift 5 (2019) ctrl-s in UEFI required to be able to change to AHCI mode and other settings. https://askubuntu.com/questions/1217061/installation-on-acer-swift-5-freezes-no-partitions-shown

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.
