I have a netbook which, left to its own devices, will always boot to Windows, and cannot be made to boot to anything else from the UEFI part of whatever we're supposed to call the BIOS these days. It does not honour DefaultBoot, always resetting it to Windows, but for some reason does honour NextBoot. So once Linux is running, a script sets NextBoot to grub. Unfortunately, there's no simple way to set NextBoot from Windows, so after the odd occasion when I run that, I need a rescue USB to get back to grub. There seems to be a lot of problems with the EFI commands operating BIOSes properly, so I wonder if good old MS requires compliant manufacturers to get it wrong deliberately. For the curious, I occasionally need to run Microchip MPLAB, the old pre-Java version which doesn't do Linux. It only just about does Windows... I used to think Serif software was buggy until I tried Microchip stuff. -- Joe
