Systemd-boot does not see Windows

Hi,

I just reinstall my Archllinux and after installation done, systemd-boot does not see my Windows partitions.

Output of fdisk -l:

Disk /dev/sda: 698.7 GiB, 750156374016 bytes, 1465149168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 67275A22-A886-4745-8A44-5C967EC65535

Device          Start        End   Sectors   Size Type
/dev/sda1        2048     206847    204800   100M EFI System -> /boot
/dev/sda2      206848     468991    262144   128M Microsoft reserved
/dev/sda3      468992  660549631 660080640 314.8G Microsoft basic data
/dev/sda4   660549632  668938239   8388608     4G Linux filesystem -> SWAP
/dev/sda5   668938240 1088368639 419430400   200G Linux filesystem -> /
/dev/sda6  1088368640 1465149134 376780495 179.7G Linux filesystem -> /home

During the boot, I got my arch entry and "Reboot Into Firmware Interface", that's all.
I disable Fast-Boot and using UEFI native boot.

The wiki say's that Windows will be automatically detected... What's wrong ?

Thanks.

Re: Systemd-boot does not see Windows

Did you wipe the ESP, or mess with the other files on it in any way? If not, where is the Windows loader located on it?

Re: Systemd-boot does not see Windows

What's in your /boot/EFI/Microsoft/Boot/Bootmgfw.efi ?

Yes, I format the /boot partition during the installation.

I don't see any any file like /booy/EFI/Microsoft/Boot/Bootmgfw.efi in the ESP, I expected systemd-boot to create it, no ?

No. You wiped out Windows' boot files, of course it doesn't show up anymore.

Argh... There is a way to generate it ? Or I need to reinstall Windows too ?

You might remember this conversation. Things like this happen the other way round as well. This is the exact reason, why I use refind and don't mount the ESP as /boot in a dual boot scenario.

I do recall it (it was only a day ago after all), but I don't see how that would have made any difference in this scenerio.

You can probably do it with BCDEdit, but I haven't messed with that for a long time.

Use a Windows install disk, it should come with a recovery option.

Thanks for your replies, I'll check with BCDEdit.
