Push end to go to bottom of list and up arrow once.
That is how I reliably do it.
I depends on age of system of course.
Might be worthwhile trying from the bottom though instead of arrowing
down through a growing list of options.

I understand this in principle now; but either something is odd or
more likely, I’m still just confused.
When I run efibootmgr, I get the following:
BootCurrent: 0001
Timeout: 1 seconds
BootOrder: 0001,0000,0004,0005,0002,0003
Boot0000* Windows Boot Manager
Boot0001* ubuntu
Boot0002* Generic Usb Device
Boot0003* CD/DVD Device
Boot0004* UEFI: PXE IPv4 Intel(R) Ethernet Connection (17) I219-LM
Boot0005* UEFI: PXE IPv6 Intel(R) Ethernet Connection (17) I219-LM
So:
Since Boot0000* Windows Boot Manager is the first item in the list, I
should be able to make the machine boot to Windows by setting
GRUB_DEFAULT=0, and then running update-grub, right? Only problem is
GRUB_DEFAULT is already set to 0, and with this setting, the machine
boots to Linux. Therefore, I tried grub_default=1, but the machine
still boots to Linux.
I also tried grub_default=saved, and then playing with the
grub-set-default command. Whether I set it to 0 or 1, I still end up
in Linux.
Playing with the grub-reboot command yields similar results. No matter
what values I use for any of these commands, I either end up booting
to Linux, or to a place where I don’t have a screen reader and can’t
figure out what’s going on.
If I didn’t know any better, I would almost think that I am actually
booting to the Windows Boot manager, but the Windows boot manager is
defaulting to load Ubuntu. Is that even possible? I can’t imagine the
Ubuntu 23.04 installer would have modified the Windows boot manager as
well as installing Grub?
At this point, I may have to connect a monitor and resort to sighted
assistance. Very bizarre indeed.
Thanks again,

Hi,
I can directly edit the grub config file. In my setup, I turned on the
beep, set timeout to -1 which will wait for a response forever, and
also set the menu to visible instead of hidden. Also disable all of
the extra recovery options. When you are in a terminal window, type
sudo efibootmgr and provide your sudo password. This will tell you
what order the boot managers are in and which one is the default.
After the setup, the menu will wait forever, displaying the menu and
only give you the active boot options <windows or ubuntu>. It will
also beep when it is ready for a response. You can also use the
efibootmgr to determine what menu option to use for the default OS option.

Hi all,
On one of my machines, I have installed Ubuntu 23.04 alongside
Windows 11. By default now, the machine boots into Linux. My
issue is that I’m not sure how to reliably boot to Windows
when I want to do so. I’ve enabled the Grub beep, and after
the beep, I’ve experimented with pressing down arrow and then
enter, pressing down arrow twice, and then enter, etc. Maybe I
need to down arrow 3 or 4 times, but the upshot is I’m just
not sure. I’m guessing there are a number of entries I could
care less about such as Memtest 386 and older kernels will get
added as time passes.
What’s the best way to deal with this these days? Sounds like
you’re no longer supposed to edit grub.conf directly. I’ve
seen talk about the grub-customizer tool but I’m having issues
installing that in 23.04.
Seems like this used to be easier 15 or 20 years ago with the
old Grub. Ah well.
Thanks,

Would it help if grub saved your last boot option? In other words,
if you do boot into Windows, the next time you reboot, the default
choice will be windows? If so, the attached patch might help (if
the list allows text format patches). It's from a 22.04 system (I
don't have 23.04 installed), but /etc/default/grub has not seen a
lot of changes over time. I hope it helps.
Forgot to mention that this patch also disables the splash screen and
makes sure there's a 10 second timeout. If you don't want those
changes, but do want to save your last boot as the next default boot
option. you only need to change GRUB_DEFAULT and add GRUB_SAVEDEFAULT
as shown in the patch. I did comment out GRUB_TIMEOUT_STYLE but I'm
not sure it is needed. For more details see the grub documentation,
especially section 6.1:
