Q
What does GRUB do if there is an error during booting a config file entry (such as a disk read error)?
A
Unless otherwise told to (via the "fallback=" command), GRUB will drop into the interactive command-line after displaying the error message to the user. If the user presses enter (perhaps after some editing), then it will attempt to execute this line and if successful continue from where it left off in the config file entry.
Q
What partition does GRUB look for the config file on?
A
GRUB looks for the config file in the default root partition unless a partition name was included at the beginning of the config file name when it was installed.
To keep matters simple, it is recommended that when installing, ALWAYS use the "p" option in the "install=" command when the stage2 file is in a partition type readable by GRUB, which will force default root partition to be the same as where the stage2.

Q
What is the status of GRUB 2?
A
It is usable, but we are still making incompatible changes from time to time. It is working on PC, OpenFirmware-based PowerPC machines (PowerMac and Pegasus), EFI-based PC (IntelMac) and coreboot (formerly, LinuxBIOS), and being ported to UltraSparc.

Q
Why do you need to rewrite GRUB?
A
GRUB Legacy has become unmaintainable, due to messy code and design failures. We got many feature requests, and extended GRUB beyond the original scope, without redesigning the framework. This resulted in the state that it was impossible to extend GRUB any further without rethinking everything from the ground.
