Hi, After some trouble getting it to load my compiled grub, because grub-efi-amd64-signed was installed (I had to remove that package).
I can now confirm that the proposed patch by B Horn: <https://lists.gnu.org/archive/html/grub-devel/2025-02/msg00179.html> "fs/ntfs: Check at->attr_cur after calling next_attribute()" fixes the issue in my setup. I can also confirm that reverting just the one patch: fs-ntfs-Implement-attribute-verification.patch also helped (as in grub booted again). Best Regards, Christian
