Public bug reported:
Description: Ubuntu oneiric (development branch)
Release: 11.10
grub-pc:
Installed: 1.99-11ubuntu1
Candidate: 1.99-11ubuntu1
Version table:
*** 1.99-11ubuntu1 0

Prior setup is a Natty Install on /dev/sda5, with grub2 installed on
that same partition, as laptop has a Windows installation in /dev/sda2,
and the Windows boot manager is used as the main, chainloading to grub
when Ubuntu is desired.
Upgrade to Oneiric Beta 1 seems to have a grub2 that does not allow
itself being installed in /dev/sda5, as seen in /var/log/dist-upgrade
/apt-term.log...
/usr/sbin/grub-setup: warn: Attempting to install GRUB to a partitionless disk
or to a partition. This is a BAD idea..
/usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be
installed in this setup by using blocklists. However, blocklists are
UNRELIABLE and their use is discouraged..
/usr/sbin/grub-setup: error: will not proceed with blocklists.
...first reboot after upgrade left the Windows boot manager intact, but
choosing to boot Ubuntu with it leads to a blank screen, meaning there's
no grub2 in /dev/sda5; I find it odd that the upgrade removed it.
Workaround was to boot with a rescue CD (e.g. Natty live CD) and chroot
to /dev/sda5 to do `grub-install /dev/sda'; while this works now, this
may be undesirable for those using non-Linux boot loaders as their
primary boot manager.
