Never mix Windows with real OS's if you can avoid it. I have separate machine for Windows. Lee  On Mon, Apr 17, 2023, 1:41 PM Wols Lists wrote: > On 17/04/2023 17:52, Mark Knecht wrote: > > Later on a Kubuntu update found Windows, updated the EFI > > stuff on the Windows drive and then, I see

Re: [gentoo-user] updating /boot directory EFI

You can probably use a portage hook to do it. I haven't tested it, but something along the lines of creating a file at "/etc/portage/env/sys-boot/grub" which contains an implementation of the "post_pkg_postinst()" function. Then, you can copy the logic from the ebuild to determine whether the

Re: [gentoo-user] updating /boot directory EFI

Grub and Windows Boot Manager are bootloaders, and they can be "on" a drive, but efibootmgr is not. Your EFI is part of your motherboard, and efibootmgr is just a tool that helps you configure your EFI. The actual EFI configuration is stored on your motherboard, not on either drive. For what it's

Re: [gentoo-user] updating /boot directory EFI

I just took a quick glance at the ebuild, and it looks like it should print a reminder ("Re-run grub-install to update installed boot code!") every time you upgrade from an older version to a newer one, but it also looks like the reminder gets skipped if you're re-emerging the same version.

Re: [gentoo-user] updating /boot directory EFI

There is a catch related to using EFI without a conventional bootloader. If you want your boot menu to include details such as kernel versions, then it would be necessary to run efibootmgr every time you update the kernel. I'm not sure if the EFI variable storage is resilient to repeated writes,

When you emerge grub, Gentoo compiles and "installs" grub (and some grub-related tools) to a directory inside your Gentoo installation, just like other applications. The catch is that grub isn't like other applications... it needs to run outside of Gentoo, before Linux starts. This means that Grub
