[GRUB] GRUB can't dual boot Windows

[strugglebus]

I have 24.10 and Windows 10 installed on the same drive. I cannot use GRUB to boot Windows. When I try, it says "error: cannot load image. Press any key to continue."

Also, if I then try to boot into Kubuntu immediately after, it fails that too. It says something along the lines of "load the kernel." So, I have to restart, choose Kubuntu first, and only then will it work as expected.

The only way to boot into Windows is to select it as priority in UEFI, bypassing GRUB entirely.

I had exactly the same setup and hardware with 24.04 and never had this problem. Is there any solution to this in the pipeline, or should I just downgrade to 24.04?

I had the same problem. At first it drove me crazy. This is a known bug. Until it is fixed can boot in to Windows by using your by using your computers firmware. You can also manually install the unsupported fix in the link below or wait for a supported fix to be released.

Your computer should have a boot hotkey to select a one-time boot change, instead of going into the firmware settings and making a change there.
Mine is the F9 key.

As the fix is in Proposed for testing, it should not be too long before it goes out officially, if there are no issues with this.

Yes, on my computer my Boot Menu key is F12. I did not make any changes to the firmware.

Oh I didn't know that, thank you.

I will probably just stay on Windows a little longer, but it's good to know they're working on a fix.

Thank you again!
