Yes, it does require re-writing the MBR. This is because Grub stage 1 is in the MBR, and it needs to know where on the disk Grub stage 1.5 is. When you upgrade Grub, the location changes. Stage 1.5 is the part of Grub that know how to read file systems, and can then load the rest of Grub. Remember, all stage 1 can do is load a chunk of code from a specific location on the disk, and the location is part of the code stored in the MBR when you install/upgrade Grub. Why would you think that upgrading the boot loader would not re-write the MBR?On Tuesday 17 June 2008, M A Young wrote:On Tue, 17 Jun 2008, Maurizio Marini wrote:I would advice any list member that it is in the wild a issue regarding grub and mbr.I don't know if this is relevant, but F8 grub (unless the latest update has been written to the boot sector) can't cope with filesystems created on F9 because of the inode size change. So it is definitely a good idea to upgrade grub if you are upgrading. Michael YoungWhich may be a good idea, Michael, but does this require the silent re-writing of the mbr to accomplish this? For existing, already setup and working drives, I don't think so.
