This is the area at the beginning of the disk, before the first

play with gparted (shrink the partition, then move it), or you can do
like I did, which is to dump the first partition, change it to start at
2048 (shrinking it a bit), making a new file system on the new
partition, and restoring it.
There is a way to force grub2 to install on systems with small starting
areas. I have a system with only 64 sectors (0-63) running grub2 just fine.
Yes, preupgrade should catch these cases before doing any work. Since
I've gone through all the pain on several systems I'm too tired to file
an RFE.
The more I think about this the more bizarre it is that preupgrade
doesn't catch this.
Almost all (all?) users of preupgrade are using grub1.
As I understand it, most (all?) grub1 systems have the first partition
starting at 63.
Any system with a first partition starting at 63 will be bricked if it
runs preupgrade to F16.
Therefore, most systems using preupgrade to F16 will be bricked.
Am I missing something?
