About reboot into firmware configuration interface

If I remember correctly, isn't that one of the entries that are auto-generated by gummiboot, along with windows entries? Moviuro (talk) 12:41, 15 March 2015 (UTC)

AFAIK, there aren't any autogenerated default options in the Gummiboot boot manager to reboot into the firmware. I only have the autodetected efiboomgr entry which appears when Windows is installed and the entries I defined manually. -- wget (talk) 13:08, 15 March 2015 (UTC)
I spent some time googleing about this issue. Without success. So it would save time and pain to add some working example. It's a useful feature. --Cschlote (talk) 00:26, 16 March 2015 (UTC) And I don't have a Reboot into device firmware entry, nor the EFI default loader Moviuro (talk) 22:35, 21 March 2015 (UTC)
I already found several real machines, which will either show none of these entries, or just one of them. Only a VM shows all entries. --Cschlote (talk) 12:32, 23 March 2015 (UTC)
Well, this picture was taken on my Dell Latitude (E6430). Moviuro (talk) 15:28, 23 March 2015 (UTC)

$esp pseudo-var

I'd suggest replacing $esp that's prominent in the article with the standard /boot, i.e. replace

$esp is used to denote the mountpoint in this article.


In this article, /boot is used as the mountpoint.

And replace $esp instances accordingly. Changing the mountpoint is immediate to anyone who wants to do so, so another pseudo-var isn't required.

In addition, it's confusing to those who wish to go with the recommended /boot mountpoint. -- Alad (talk) 10:33, 5 January 2016 (UTC)

While that could make sense, we'd create an inconsistency with all the other boot loader articles, which do use $esp as well: GRUB, Syslinux, EFISTUB and rEFInd. Personally, I don't think that using a variable like that is creating confusion, especially after [1]. — Kynikos (talk) 07:12, 9 January 2016 (UTC)

Keys inside the boot menu, clarification

once you use keys to change timeout (-,T,+,t), this setting is saved in a non-volatile EFI variable; in this way `loader.conf` setting is overridden; a) how to clear the non-volatile EFI variable? b) how to show values of non-volatile EFI variables? --nTia89 (talk) 14:22, 27 May 2016 (UTC)

The section about Windows 8+ overriding boot settings is incorrect

I have a dual boot with Windows 10 and it does not override your boot settings or make Windows the default at each boot as explained in the wiki (it might during a major upgrade that work more or less as a new install, like Windows 8 -> Windows 10).

The fact is that, Windows normally manage the default boot efi file $esp\boot\efi\bootx64.efi and keep it identical to $esp/EFI/Microsoft/Boot/bootmgfw.efi . This file is often updated (I don't know if it is at every boot, but very often). The default installation of systemd-boot put also a copy of itself at the default $esp\boot\efi\bootx64.efi and this can gives a conflict because it will be overwritten by Windows. If we manage to correctly put a default boot entry in the firmware that is not $esp\boot\efi\bootx64.efi, there will be no problems. If we have a motherboard that can only boot $esp\boot\efi\bootx64.efi then and only then we are in trouble and the work around described in the wiki can make sense. It would be safer not touching $esp\boot\efi\bootx64.efi, I think Windows expect we do not touch this file.


add a section which talks about splash feature. --nTia89 (talk) 09:40, 9 July 2016 (UTC)
