I have an HP 500-413nl (a desktop) and Windows 10 keeps changing the boot order in UEFI/BIOS every time, so that if I want to boot Ubuntu 16.10 (64-bit) I always have to press F10, thus entering the BIOS setup and changing boot order…

Is there a workaround for my PC? What should I do? I'm a little desperate.

P.S.: I have already disabled "Secure boot" and "Fast/quick boot" in the BIOS and "Fast startup" in Windows options / Control panel.

  • Did you change the boot order in the UEFI/BIOS settings? I had to change the boot order sequence for the drives after creating the dual-boot setup. I'm using an MSI laptop, not HP.

  • Did you try renaming the bootloader and change the label to exactly match the Windows version? That might make things stick, at the cost of making the manual boot more confusing.

  • Some HP have a "Customized" boot buried pretty deep in settings: ubuntuforums.org/… and one of later answers: askubuntu.com/questions/244261/…

  • @JKandy-drew Dumb question, but did you save the changes at UEFI? I just don't see a reason why Windows would be modifying UEFI/BIOS settings without you asking it to do it (if possible), but I wouldn't be surprised if it's really doing that.. haven't come across this problem.

I also faced the same issue that Windows 10 (Education) automatically, on startup, moves the Windows Boot Manager EFI entry to the top again. If I changed it, after restarting with Windows, the next boot skipped Grub and directly booted into Windows. This is how I sovled it:

I would recommend the tool EasyUEFI http://www.easyuefi.com/ to view and change some EFI related settings.

  1. Open the tool and select Manage EFI Boot Option

  2. Take a loot at the exiting entries. The two important ones for me are:

    Description:Windows Boot Manager
GPT partition GUID:{505E666C-00CD-4654-BB80-FBD2C6F9F191}
Partition number:2
Partition starting sector:923648
Partition ending sector:1128447
File path:\EFI\Microsoft\Boot\bootmgfw.efi

    And:

    Description:Ubuntu 16.04
GPT partition GUID:{505E666C-00CD-4654-BB80-FBD2C6F9F191}
Partition number:2
Partition starting sector:923648
Partition ending sector:1128447
File path:\EFI\ubuntu\grubx64.efi

  3. The next step is to make sure that Windows does not use its own bootmgfw.efi file again, but rather grubx64.efi. To do so, don't move an Ubuntu EFI entry to the top again (i.e. that's the problem we have), but just set the file path for the Windows Boot Manager to \EFI\ubuntu\grubx64.efi. You can also do this from the administrator command line:

    Bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

    Now, Windows should not change the EFI settings anymore and on every boot, GRUB is the default. As GRUB ideally already identified your Windows OS, it also contains its value in the grub settings.

    If Grub is not configured properly, refer to this or this post to add Windows to Grub, as you can now boot into Ubuntu again. Sorry, but due to insufficient reputation, I could not provide more than 2 links in my response.

    @Kartik my post above concerns UEFI and not BIOS, which are two different things (see here)

    This is Shareware right? Anybody know a free tool for this?

    My god thank you so much, I was pulling my hair out from having windows destroy my efi config every time it was updating.

    I got it to work on Windows 11 (22H2 build 22621.1194) and Ubuntu 22.04.1. Another answer said to use bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi, but that showed a warning right before GRUB had loaded whereas using …\grubx64.efi worked great out of the box. Many thanks!

I had this problem and solved it by setting a password in the UEFI/BIOS for accessing it. Apparently, when a password is defined, windows can no longer make changes in the UEFI/BIOS. The computer is a Lenovo.

  • HP 500 105ed didn't help. Windows changes the boot order anyway.

  • Thanks. I thought this was the easiest way. This is on an ASUS laptop, Debian testing and win10.

My Sony laptop was also changing the boot order upon start-up. Another alternative that worked was to use EasyUEFI to disable the Windows Boot Manager EFI entry.

This left the existing Ubuntu boot option as the highest active.

I executed this on windows, so windows uefi will boot into grub:


 bcdedit /set '{bootmgr}' path \EFI\ubuntu\grubx64.efi
