I have been researching this topic a lot in order not to make a stupid post, sorry if I do so regardless.
I have a Windows 10 system alongside my Arch system. It is in another partition. It, however, does not appear in the GRUB menu.
I tried os-prober but the output is empty. Yes, I have uncommented the line in /etc/default/grub
I have journalctl outputs this regarding os-prober

The UUID I got it from
blkid /dev/nvme0n1p4I am lost at this point, I could use some help from whoever is willing to help, please.
Thanks in advance, sorry if it is a small dumb fix that I missed

Post the output of `lsblk -f`.
I tried adding a custom windows entry but it failed because it said
Please do not paraphrase commands and output. Post the full, actual command used and its actual output.

Here is the output, sorry I didn't want to add unnecessary stuff but my mistake

The Windows EFI partition (nvme0n1p4) looks like it isn't mounted, which is what the GRUB Wiki entry for Windows recommends to do before running os-prober (as root). Try that and see if that works.
I don't know where you get that 8868f6d5-xxxx UUID from, since you omitted the output from the blkid command. lsblk reports 5279-FB74 instead.

I tried mounting it last time, it still didn't show. I will mount it now and show output
lsblk -f !205

First thing I noticed reading through my logs, I put the PARTUUID instead of the UUID from blkid. That was my first mistake as far as I can tell. Still does not answer why os-prober and by extension grub is not finding Windows

If you have a "Microsoft" entry showing up in /sda/sda1 (mounted to /boot), I would guess that GRUB *did* add an entry for Windows. I'm guessing that the EFI partition on /nvme0n1/nvme0n1p4 is the original Windows EFI. I'm not a GRUB user myself, so I don't know if there's an easy way to have os-prober be verbose when you run it manually. Try `man os-prober`. Since 'sh' is a dependency for os-prober, it might just be a script you can inspect yourself to see if there's command line parameters to make it more verbose.
Either way, if you want to add the entry manually, make sure to use the correct UUID (5279-FB74) and boot command. I am guessing you will want to instruct GRUB to chainload Windows. For an example, see post #2 here: https://bbs.archlinux.org/viewtopic.php … 0#p1922510.

Thank you for the instructions, I will follow them. You have been of utmost help. Yes, the one on nvme0n1p4 is the original one. I will follow your advice and just add it manually following the post you sent, some things I guess just don't work always as intended. Thank you once again for your time!

Still, if someone can see this and hop to help... I would LOVE to know why it did not create a grub entry, maybe there is something that I did wrong. The problem is fixed I just am left wondering. Thank you again for everything

I checked and os-prober is just a bunch of sh scripts. Take a look at /usr/lib/os-probes/mounted/20microsoft. Also list the contents of /mnt/win and compare that to what the script is looking for. Post both here in code tags if it's not clear/obvious what's going on.
