Hello Stack Overflow Community, I'm encountering a recurring problem where Windows 11 becomes unbootable after I install Ubuntu alongside it using a custom autoinstall.yaml file. Despite careful configuration to preserve the Windows partitions, each time I perform the installation, the issue persists.
Here's what happens: After the Ubuntu installation completes, I attempt to boot into Windows 11. Instead of successfully booting, the system hangs indefinitely with the Windows loading circle. It appears the boot process initiates but never completes, suggesting a possible corruption or misconfiguration in the boot loader or the EFI partition.
I've checked the partition integrity and configurations, and everything seems in order, with no partitions deleted or formatted unintentionally. Here's the content of my autoinstall.yaml file that I'm using for the Ubuntu installation:

I'm wondering if anyone else has encountered this problem and how you resolved it. Specifically, I need to know:
Any common mistakes in the configuration that might affect the Windows boot loader.
Tips for ensuring that the GRUB and Windows Boot Manager can coexist without issues.
Any advice or guidance would be greatly appreciated!
Additionally, here is the output of lsblk which shows the current partition layout on my system:
