You mention using a chroot: by coincidence I just had a similar problem installing Devuan on a dual-boot system. When I installed grub from inside a chroot, os-prober couldn't find the Windows partition. However, after I rebooted into the new Devuan installation, I ran update-grub again, and this time it found Windows. So you may want to try running update-grub again, just to see if it picks up Windows this time. Be sure to edit /etc/default/grub per kapqa's instructions to enable os-prober.

@rosun, it is possible that future forum visitors and those searching, might be better served if we knew which version of "Windows" you are referring to...

also you say you are still able to boot "Windows" via "BIOS" but are you really using the "old" bios or the "newer" UEFI/Secure-Boot/etc functionalities?

we probably should not just assume you are using an older version of windows on an mbr-formated hard-drive in an older garden-variety mini-tower(maybe even with a floppy-disk still protruding from the drive-slot).

and by "floppy-disk" i refer to the 3.5inch version and all the wonderful sounds associated with it's operation and utilization

grabbed a wikipedia link because i was too lazy to take a current photo of one of my said-same mini-towers with disk protruding(the grandkids used to say it was the "computer with it's tongue sticking out" ha!)

if dualboot, you can check in

/etc/default/grub

and uncomment

GRUB_DISABLE_OS_PROBER=false

for windows partition recognition

afterwards, is needed

[color]sudo update-grub[/color]

Presumably you need to edit /etc/fstab to add a line for it, like

/dev/sdb1  /home  ext4  defaults,noatime  0  1

But with details suitable for you.

Check "man fstab" for the details.

Thanks to both for your reply @golinux and @delgado.
In the mean time I went to reinstal the system, and this time it installed the bootloader, but has not picked up Windows partition. I am still able to boot it via BIOS. My /home partition has not been assigned. How can I do this? I am setting this on a pc where it's going to stay for many years, hence this system choice. I am not a programmer, so happy to accept a detailed assistance. Thanks.

The following may or may not apply ... .

Assuming you already did

# update-grub

Does grub's "advanced options" menu show something useful?
Is a kernel installed?
Are you booting in UEFI or BIOS mode? Can you switch between them?
Did you mount the EFI-partition in excalibur?
chroot probably menas there is a functioning linux installation. Does this grub find devuan excalibur when running update-grub?

Welcome to Devuan, rosun . . .

I can't begin to answer your question (for many reasons) but probably no one else can either because there is no information about which installer you used or any other important installation data. Please do try to give us more details.

I just installed excalibur but it won't boot. I have tried installing the bootloader and chroot but none would boot. Can someone assist with the setup?
After boot I am presented with GNU Grub
