Bug#707653: grub2-common: After Grub 2.00-14 upgrade, system failed to boot (rescue, old grub 1.99 still in mbr)

[Gleb Golubitsky]

Hi all,

This (or maybe another?) bug also affects RAID-based systems. I have my system 
installed on RAID 1 (fakeraid). After upgrading  1.99-27.1 -> 2.00-14 it was 
impossible to boot system. 

Workaround for those who met this: boot from livecd, chroot, downgrade grub to 
1.99-27.1 (from Wheezy repo), manually grub-install & update-grub2.

Details for Debian developers & maintainer (please let me know if u need any 
futher information or help to locate and fix this issue):

Path `/boot/grub' is not readable by GRUB on boot. Installation is impossible.
