Well I had thought I should write a nice review of Mageia 3 here because Debian 7 installer fubared the partitions and left me with overlapping partitions which means that Gparted cannot detect the partitions either.
So I moved on to Mint 15 and that installer came to a halt there too.
Mageia 3 found the free spaces and let me install just fine! So yes for a dual boot Mageia seemed to be the best solution. That installer was simply the only one that would get the job done.
So after a boot I could pick windows or mageia 3 and life was good?
Eh not quite I could not access my windows folders so I checked out my partitions with gparted and it could still not find a working partition so the overlaped partitions were still a problem.
I used some rescue cd s to brutally remove old windows FAT recover and install stuff and also those older linux directories - rewrote the partition tables and now gparted could find my partitions.
I installed ZRAM and removed task-kde-minimal and installed task-xfce to make the system slimmer and set it up until it was so perfect that I had tears in my eyes.
Xfce4 comes with a dropdown terminal so I could leave my favorite guake out of it.
I installed tmux and set up this ladies mail and twitter and she was happy as a peach too.
She does not realize that she is using Linux she simply found it was better than "that other stuff" (XP).
Mageia lets me import her windows documents with ease and also the MS-fonts from Windows. That part is a strongpoint when dualbooting.
Those draktools are still a great asset.
BUT! For some reason the keybord stops working in the midlle of a post or in the terminal. Other times it decides to write the last typed letter forever like I was holding down that key.
The only way to fix it is to reboot - which I have done 4 times during this post
I do not know what is the reason but it is a show stopper.
So for now I must conclude that Mageia 3 is great for installing besides Windows. And the functionality after that is.......not great.
While it is working, it actually is great but those complete stops (in the terminal too) just kill me

Still:
Mageia 3 made it this far; Debian 7 and Mint 15 did not.
After I have solved that overlapping partitions problem they will probably install just fine and if this continues I will reluctantly have to remove Mageia 3 again.
.. And give Debian 7 another go....
Old laydies want stability - you see....
(EDIT: Hey I was able to finish this rather long post now - maybe disabling Amarok helped

I will leave Mageia 3 here for a while longer to see if it s mood improves - It could be a capacity problem)
