I have been very happy with wubi 10.04 running alongside Windows (on two laptops running XP and 7, respectively).
Before finally moving to wubi 12.04 I'd like to run my old 10.04 together with the new version by using triple boot (XP /wubi 10.04 / wubi 12.04) or - on the other laptop (WIn7/ wubi 10.04 / wubi 12.04).
How can I do that? I see that the wubildr and wubildr.mbr are different in the two versions and I am afraid that they have to match the respective version.
I am also afraid that the procedure, if there is any, is different for XP and 7.
Thanks for hints, D-E
