hi as the title suggest is there any way to make warcraft run on linux while having the original installed on windows

Go into your windows partition, by going into /mnt/windows/. It should be auto mounted, if not type "mount /mnt/windows" in either root or user. Ill explain more if needed.

if the expansion isn't already installed in windows you would probably have to copy the registry info from windows into ur wine registry to get it to install.

not in neway a linux guru, but i'm sure that should be 'mount /dev/hd** /mnt/[win]' ([win] is can be anything u want and hd** would represent your win partition more than likely hda1 if windows was installed first)
so from a terminal type 'mkdir /mnt/WinC'(i actually prefer lower case to make things easier 'cos linux is case sensitive).
then type 'mount /dev/hda1 /mnt/winc' (as i said linux is case sensitive so spell it exactly the same way you did when u created it)
now u should be A for away to install the expansion! you will however run into preblems if you installed warcraft3 in 'c:\program files', 'cos linux doesn't like spaces in it file/folder names so ur stuck!! if u change it to programfiles then none of ur progs in win will work!!!

if, on the other hand u didn't that's GOOOOOD!! jus' mount ur cdrom, same as bfore, 'mount /dev/cdrom /mnt/cdrom'
then 'wine /mnt/cdrom/setup.exe' ............ then just pray everything works!

hope that helps dude!!
