I work with a Grub boot for Win11 / Debian on the same disk (work provided laptop without the persuasion to change my employer MS-First policy) but one of the lucky ones I guess. No problem for 2 years now.
Only thing after a big Windows update it forgets its TPM Bitlocker key for its own partition. Must type it like once in 2 months manually.
I just see those foundation onboard / leaves from afar … but isnt the retention rate way to high to do actual foundational stuff?
