Change the boot order to boot Ubuntu first after Windows installation

us flag

I had ubuntu at first and installed windows to work on something, the installation is clean and I can boot both operating systems, the problem I have is that I want to see GRUB (I want ubuntu boot at startup) and not windows but It went vice versa after I installed windows. I can now choose ubuntu from my laptop's BIOS settings and the grub is fixed too by repairing in the live ubuntu environment. enter image description here But how can I choose to ubuntu boot first instead of windows?!

In UEFI > Boot is where you're supposed to define the priority

I can't achive my goal with this solution, I can just indicate which devices should boot first, for example flash or something else, isn't it?

You will need to consult the documentation for your motherboard. Choosing the boot volume or setting boot priority is a feature of your motherboard firmware and is unrelated to any operating system. The implementation is not consistent between motherboards.

Most systems support efibootmgr changes. A few like HP will only let you change order in UEFI settings (not the UEFI boot menu). See `man efibootmgr` This shows both delete of old UEFI entries & the change order with efibootmgr -o command option. https://askubuntu.com/questions/485261/change-boot-order-using-efibootmgr Note that major updates to Windows may reset UEFI boot order to Windows, just like major updates to grub resets UEFI boot order to Ubuntu/grub. You should always be able to boot any installed system from UEFI boot menu. Grub only boots working Windows.

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.
