[Bug 463015] Re: Both fat and ext[234] boot sectors present at once cause confusion

[Phillip Susi]

If you are going to format the whole disk, then you don't want any
partition table that may already be there do you?.  As for the boot
code, well, you have to reinstall LILO after you format and put a new
kernel on the disk anyhow.  If it is a grub MBR, well, you trashed grub
anyhow when you write to the following 32 sectors.  If it is an EFI
system, you corrupt the GPT, so who cares about the protective MBR?

Title:
  Both fat and ext[234] boot sectors present at once cause confusion

Status in “e2fsprogs” package in Ubuntu:
  New
Status in “grub2” package in Ubuntu:
  New

Bug description:
  Binary package hint: grub2

  grub-probe incorrectly identifies my ext3 partition as containing a
  fat file system.  This means it can't boot without manual tweaking.

  I suspect the problem is that my partition contains stale fat
  signatures... this is probably a common problem, as mke2fs often
  doesn't wipe old signatures.

  I attached first 8k of my file system for testing purposes.
