Hi http://www.chiark.greenend.org.uk/ucgi/~cjwatson/blosxom/2010/08/28
Colin Watson would like to hear from you. ....... " If you find that running Windows makes a GRUB 2-based system unbootable (Debian bug, Ubuntu bug), then I'd like to hear from you. This is a bug in which some proprietary Windows-based software overwrites particular sectors in the gap between the master boot record and the first partition, sometimes called the "embedding area". GRUB Legacy and GRUB 2 both normally use this part of the disk to store one of their key components: GRUB Legacy calls this component Stage 1.5, while GRUB 2 calls it the core image (comparison). However, Stage 1.5 is less useful than the core image (for example, the latter provides a rescue shell which can be used to recover from some problems), and is therefore rather smaller: somewhere around 10KB vs. 24KB for the common case of ext[234] on plain block devices. It seems that the Windows-based software writes to a sector which is after the end of Stage 1.5, but before the end of the core image. This is why the problem appears to be new with GRUB 2.
