Then set the partition and OS path:
bcdedit /create /d "Windows 10 on D:" /application osloader This returns a GUID like xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx . Copy it. add boot option windows 11
Note: Easier to use GRUB. But for direct boot: Then set the partition and OS path: bcdedit
bcdedit /create /d "Ubuntu Linux" /application osloader bcdedit /set GUID device partition=G: bcdedit /set GUID path \ubuntu\vmlinuz bcdedit /set GUID options "root=/dev/sda3 ro" add boot option windows 11
