Missing windows boot entry

After more than a year, I need to boot into windows, and find the windows entry is missing in the boot menu.

bootctl sees the windows installation, but "bootctl install" does not add an entry for it. I must be missing something silly.

# bootctl 
Using EFI System Partition at /boot.

Re: Missing windows boot entry

What use would a dmesg be? This is happening before the system boots.

Angelo, do you have a Windows entry in your systemd-boot config (/boot/loader/entries/*.conf)?
If so then post it, if not then that's your problem.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: Missing windows boot entry

There are only linux entries in /boot/loader/entries.

I looked at the seemingly related thread https://bbs.archlinux.org/viewtopic.php?id=214239 .
It seems the issue there was no timeout, hence boot into arch automatically, and the windows entry was there all along.
However, comment from ewaller there suggests that bootmgr should create the entry automatically. Do I need to create one manually?

Not sure if this is relevant, but windows appears in efibootmgr as well:

# efibootmgr 
BootCurrent: 0001
Timeout: 0 seconds
BootOrder: 0001,0002,0000
Boot0000* Windows Boot Manager
Boot0001* Linux Boot Manager
Boot0002* UEFI: PM951 NVMe SAMSUNG 256GB, Partition 1

Re: Missing windows boot entry

Ruling out the obvious: Did you run "bootctl update" to actually update the config?

slithery's reply makes sense to me - the issue is before booting. Is there something I might look for in dmesg output?

Running "bootctl update" and "bootctl install" does not generate an entry in /boot/loader/entries .
I will see later if there is nonetheless an entry in the boot menu.

Re: Missing windows boot entry

Are you ever actually booting into systemd-boot? You shouldn't have to generate anything explicitly, given the standard paths systemd-boot should detect and create a Windows entry (dynamically, you are not going to have a file in your entries directory for that). What's the output of 

tree /boot #Requires the tree package

Re: Missing windows boot entry

There is no Windows UEFI binary. Have you formatted the partition during initial  Arch setup? You will have to repair that. Get the Windows installation media and google for a guide on how to restore your Windows UEFI bootloader

Re: Missing windows boot entry

I have definitely used Windows after the arch install (a few months ago, though). I did not touch the partitions since then.

I see instructions for this at
http://www.dell.com/support/article/us/ … pc?lang=en

Will this interfere with the arch installation? Is this a risky procedure?

Re: Missing windows boot entry

The only thing that should possibly happen (although there's no sane reason for why this would happen) is that the ESP partition gets cleared and you'd have to reinstall systemd-boot and maybe the linux package from a chroot.
