These wiki instructions are really odd. I don't buy their recommendation to convert back to MBR; we'd actually prefer people stay with GPT if that's how their disk comes, and I expect that staying with GPT would fix this problem.
grub-setup is just telling it how it is; the message is not a grub2 bug in and of itself. You should be able to reboot successfully (though keep a live CD handy!), but the unreliability of blocklists means that you may have to rerun grub-install more frequently than you otherwise would - for example, after major filesystem rearrangements. http://grub.enbug.org/BIOS_Boot_Partition has some further details here. -- [Lucid] Upgrade of grub-pc: "Your embedding area is unusually small. core.img won't fit in it." https://bugs.launchpad.net/bugs/515724 You received this bug notification because you are a member of Mactel Support, which is a direct subscriber.
