Title:
  no grub unless waking from hibernate

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Binary package hint: ubiquity

  This might not be an installer issue, but I thought this was the best
  place to put it.

  After an apparent successful and straightforward (auto-partitioning
  and default grub options=MBR) dual-boot install of Lucid Lynx Netbook
  Edition on my brand new Samsung N210 netbook, the system booted
  directly into Windows 7 Starter as if nothing had changed.

  A bit puzzled by this, thinking grub might not be correctly installed
  in MBR, I tried to reinstall grub into MBR manually by booting USB
  installation media and issuing 'grub-install /dev/sda --root-
  directory=/media/<rootdisk-mountpount>'. This didn't affect the boot
  sequence at all.

  Next I tried to boot from the USB media choosing "Run from first
  harddisk" at the initial boot menu, this brought up grub and let me
  boot my new Ubuntu which seemed to run flawlessly.

  Another reboot brought me again directly into Windows 7 Starter.

  Conclusion; Grub seems to be in MBR and bootable when forced from the
  USB media, but at normal boot BIOS somehow bypasses it and commits
  kamikaze directly into Windows.

  After a cup of coffee (or three and maybe some off-topic discussion
  with colleagues) Windows 7 Starter had hibernated itself. Now bringing
  the system up from hibernation revealed the grub menu, lo and behold!

  It took me a couple of guesses to figure out that it was actually the
  hibernation that triggered loading of grub, but now I can reproduce
  this every time. Hibernation of either Windows 7 Starter or Ubuntu
  10.04 at last poweroff brings up grub. If neither of these were
  hibernated, grub doesn't load and Windows 7 is started directly.

  I thought hibernation was handled by the operating system
  independently of BIOS and bootloader, but somehow this doesn't seem to
  be the case. Anybody got a clue on what is going on here and how I can
  get grub up at every boot?
