Unable to access GRUB menu for password reset in Ubuntu 20.04.3

pn flag

I am facing difficulty in resetting a lost admin password for Ubuntu 20.04.3 According to various online resources, the recommended method is to access the GRUB menu, enter recovery mode, and reset the password from there. However, when I press Esc during the boot-up process, instead of displaying the GRUB menu, a series of commands start running and eventually I end up on the home screen.

Is there an alternative method or a workaround to access the GRUB menu in this situation? I really need to reset the admin password, and any help or suggestions would be highly appreciated.

Does this answer your question? [How do I boot into a root shell?]( See [this answer]( If you have legacy BIOS you need to hold shift. Of course none of these methods will work if your BIOS is not booting your Ubuntu partition. If the problem is with BIOS boot priority, review the documentation for your motherboard for the procedure on your particular hardware.

Isn't it supposed to be the "Shift" key instead ... Plus there is always the forceful way like with most OSs if you forcefully interrupt the boot process by rebooting early ( Ctrl+Alt+Delete ) in the boot process, it will show the GRUB menu on the next boot.

Your details imply you've not applied security fixes/upgrades in a very long time if you're using Ubuntu 20.04 LTS. A fully upgraded system will report as [20.04.6]( with you more than [12 months]( behind on security fixes. Also note the dates are ISO release dates, with installed systems upgrading in the week+ before ISO release date. Are you using Ubuntu? (Ubuntu based systems will report as what they were based on & may not upgrade)

I've tried with Shift key (pressed multiple times, hold the key) but nothing happens in that case.

In this case, follow instructions here and you will be able to change your password after the `chroot` step.
I sit in a Tesla and translated this thread with Ai:

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.
