The above  description, gives the impression  that Solaris (80
gb is  your primary master  as seen  by the BIOS)  and Windows
(160 gb) is perhaps the primary slave or some other.

Windows can  only boot from  a primary master. If  the windows
HDD is a slave or secondary  master, you would have to map the
device to be seen as a  primary master. To check if Windows is
seen as (hd0) by grub, from the grub command line type:

root (hd0,0)

... if  this shows  as Windows  type then  windows is  seen as
the  primary master.  Unless the  windows boot  record on  the
partition  is corrupted,  it  should work.  However, if  'root
(hd1,0)'  shows windows,  then  you need  to  map the  devices
around.

I am not  sure of Solaris grub, but under  linux, I have faced
this problem  before and  I got things  working by  adding the
following to grub.conf in linux grub:

map (hd0) (hd1)
map (hd1) (hd0)

(This needs to be added before any root command).

Just a guess ... may work. Try it out.
