[Chester LUG] GRUB2

[Roger Gibson]

Using Ubuntu 10.10  dual booted with windooze7 and having probs with 
GRUB2.  When I install UBUNTU alongside Windoze7, the installation finds 
Windoze OK and it comes up in the boot menu (Disc had already been 
repartitioned).

However if I apply UBUNTU updates, GRUB loses Windoze7, and I can't see 
an easy way to keep it.  In fact if I do a sudo update-grub immediately 
after installing, it does not find the Windoze7 OS.  I think I can see a 
workaround by putting an explicit Windoze line in grub.d/40_xxxx, or is 
that the official way anyway.

What I don't understand is how UBUNTU 10.10 can see the Windoze7 OS at 
installation, put it into the boot menu, but then not see it later on.

Another bug I've found, and still not fixed concerns Thunderbird.  With 
earlier versions of LINUX OSes I've had no problem directing Thunderbird 
to the same set of data files via profile.ini as I use with Windoze.  
However, every now and again it jams in either UBUNTU or Windoze.  It's 
as if a new flag has been introduced, and if Thunderbird does not shut 
down cleanly, a restart from elsewhere gets upset.

Any ideas?  Roger.
