I installed Linux Mint 13 on my laptop which previously had Windows 7 on it, to get a dual boot machine. I did not like the appearance of the standard boot loader so installed GAG v4.10, I believe. Didn't like that either so I uninstalled it. That left me with the Windows boot manager that did not recognize Linux in the other partition. So I wiped out that partition and extended the Windows partition to its original size. Then I tried to reinstall Linux Mint. The very first installation gave me a choice of installing Mint in its own partition and that's what I had done. However, now it offers to either replace Windows or do "something else". In other words, the third choice -- coexistence between Linux and Windows -- is gone. On selecting "do something else", it was not apparent how to split the existing partition into Windows and Linux. Can anyone help me do that? Thanks.
