I have Win10, Win10 Pro, Win7, Macrium, all on the boot list.
This creates a slight problem with M$ updates, which reboot
automatically. The reboot always goes to Win10, top of the list. I can
re-order the list, but the top entry is the reboot default.
I can sit by the machine and manually choose from the POST list
but ...

Install Linux and use the grub menu. You get a list to chose from but no action means it boots the last use OS. My
windows can boot 3 times and I don't care.

Thanks for your interest.
I ran that command and got this message;

C:\WINDOWS\system32>bcdedit /bootsequence
The entry list data is not valid as specified.
Run "bcdedit /?" for command line assistance.
The operation completed successfully.

You need to find the GUID of your relevant bootable partition

with bcdedit /enum

then provide it with bcdedit /bootsequence {GUID}

that should take effect for the next boot only ...

I have the same problem being able to boot into Windows 8.1, 10 or 11 so use EasyBCD - https://neosmart.net/EasyBCD/
Free for personal use.

That's a cute little piece of software. I'm trying to think of a word
opposite to "bloatware", but can't get better than "small, efficient and unobtrusive".
It takes only 10 seconds to go through the whole process; load, change
default, exit.

You have to remember to change it back afterwards, unless there's a
one-off usage switch that I've missed.

Thanks,

Ed

Is there a program in Windows to edit the EFI boot sequence?

You mean an efibootmgr port for Windows ?

The problem there, is figuring out what the hell you're editing,
and whether the result is actually what you wanted.

Playing with EasyBCD is "much more comforting" for a Windows user :-)

The OPs "orbit" described in the post, smells of EasyBCD.

If a wider orbit is involved, that's when you might go looking for a port.

I would need to see a worked example of a multiboot (mixed Win/Linux)
before I could be convinced to test it. My BIOS for example, has
a "horrible row of icons", meant to resemble efibootmgr, and
I just avert my eyes when I see that :-) Such a mess. There might
be an icon there, to boot from an SD card... when I don't even have
an SD card reader slot.

Yes, but I understand that you can only play with the partition
contents, not the EFI boot menu entries.

It is my understanding the W10/11 includes software, maybe produced by
the manufacturer, to change UEFI settings from inside Windows.

That's a lot of cryptic boot options, from number 10 upwards. They
belong to the firmware, they are static. And there currently nothing on
USB, no CD, no other HD.


Look at another machine:

Isengard:~ # efibootmgr
BootCurrent: 0001

BootOrder: 0001,0004,0010,000F,0002,0003,0000,0005,0006,0007

Boot0007* UEFI:Network Device
Boot000F* UEFI: JetFlashTranscend 8GB 1100, Partition 1

And that machine doesn't really have Windows.
