[Bug 2078307] Re: Grub 2.12 in Oracular is unable to boot Windows using chainloader

[Mate Kukri]

Sorry to hear that you are having difficulties with Ubuntu 24.10's
bootloader. Given the testing we are doing, I have strong doubts Ubuntu
24.10 doesn't boot "2 out of 3" on the vast majority of machines, so I
suspect there is something going on with your firmware.

Please run `set debug=peimage` provide the debug output for failures
loading the kernel and Windows.

Additionally what hardware is this running on?
