Hello Daniel, thank you for sharing this, I've been searching for information on how to do this but seems not to be a highly sought after piece of information.
Last time I tried this, I noticed that any time I booted into linux (I would reboot into linux a couple times a day when necessary), it would often require the Bitlocker key again and also made standby/hibernation non working which made it unusable for me.
Did you manage to solve all these issues?
Do you have any updates for 2024, with Windows 11 and Ubuntu 22 or 23 variants?
