I need to add Ubuntu on a second Hard Drive to the Windows Boot Manager, because BitLocker doesn't work with GRUB and the Boot Device Selection is secured by the UEFI password. I tried to copy the Ubuntu Bootloader to Y: on the first Drive but the .bin file wasn't found by the Boot Manager or is corrupted. So i want to add the Ubuntu's Bootloader directly to the Windows Boot Manager. Is this possible and how?
On Datenträger 1 is Windows installed and on the second one Ubuntu.
Thanks for your help!
