done

when was your last update?

yesterday, and i do almost daily updates, 2 days once atleast.

I don't think this is needed anymore, but try to manually configure the os-prober by adding GRUB_DISABLE_OS_PROBER=false to /etc/default/grub
And sudo update-grub

it's set to false and still same issue. os-prober-btrfs works but doesn't recognize windows, a lot of users have been facing this.

seems like it has been an issue across all distos. i came across [Solved] GRUB and os-prober do not see Windows 10 on a different drive / Newbie Corner / Arch Linux Forums maybe it can help

MS Windows

Often, partitions containing Windows will be automatically discovered by os-prober. However, NTFS partitions may not always be detected when mounted with the default Linux drivers. If GRUB is not detecting it, try installing NTFS-3G and remounting.

Encrypted Windows partitions may need to be decrypted before mounting. For BitLocker, this can be done with dislockerAUR. This should be sufficient for os-prober to add the correct entry.

and more


I have no problems (Lenovo), as I have written here before in the forum.
So it's either due to missing drivers, BIOS settings (fastboot set from M$ after updates) or maybe other changes made by the user.

The easiest thing would be to set up a custom.cfg for M$.

It works also for me, also after update with os-prober-btrfs.

In-fact:

It is worth checking IMO...

I'm also on a Lenovo laptop, (Ideapad S340), windows was being recognized before the os-prober-btrfs replacement.. I even tried mounting ntfs unmount & remounting. nothing works.. NTFS-3G is installed. Windows isn't encrypted. I am able to boot to windows from the bios boot menu f12 and there haven't been any updates to windows..

oops, double, same from post #4 here.

The issue has been solved with the new update to os-prober-btrfs. Forgot to mention, thanks for the update and quick support. Loving garuda, but have few issues which I'm trying to resolve.

Anyone know why this new prober doesn't show Windows installation anymore? Just curious. Maybe needs a new thread

Update your system, it's solved.

Update your system, boot into windows, restart then go into garuda and it will be recognized.
