GRUB Menu not visible after firmware update on Windows10

jp flag

A few days back, Windows prompted a firmware update, and after the update, my laptop directly boots into Windows10, and GRUB Menu has gone. To fix this, I changed the boot order in BIOS to Ubuntu first and second Windows. It worked; GRUB Menu appeared like normal. But after this change, Windows doesn't shut down; it goes to sleep instead. I tried various troubleshooting methods to fix this shutdown, but it didn't work, so I finally restored the boot order, and the GRUB menu disappeared again. How do I fix this?

Did you redo all the UEFI settings. Update typically resets UEFI/BIOS to defaults & Windows or Ubuntu update makes its boot loader as first or default boot.

No, I just undo the Boot order settings. Okay, so the firmware update probably changed the BIOS settings to default. But, I don't understand is why windows do not shut down when the boot order is changed. Are any other changes to the settings required while changing the boot order?

Windows often has to do updates as part of both shutdown & reboot. So you may need to delay power off, so Windows can complete its updates. Do not hibernate if dual booting as that can also cause issues if you want to share a NTFS data partition.

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.
