HP - escape + F9 for UEFI boot menu, F10 for UEFI/bios settings

HP seems to be the only vendor that does not support boot order change with efibootmgr which grub uses to change order. Applies to most models.

Use F10 for UEFI settings and change boot order there. Then boot menu should show Ubuntu as first. It may be sub-menu & be sure to save settings changes so it applies.

Grub will boot working Windows.

Windows updates may turn fast start up/hibernation back on and then you need to directly boot Windows from UEFI boot menu to turn it back off for grub to work again to boot Windows.

Not boot menu, but UEFI settings menu for boot devices. And it probably is a sub-menu. If still not shown, did you install in UEFI boot mode? To see details Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed. Use often updated ppa version over somewhat older ISO with your USB installer or any working install. https://help.ubuntu.com/community/Boot-Repair & https://sourceforge.net/p/boot-repair/home/Home/

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.
