I'm trying to add Mint12 to a 100Gb partition on a Win7 machine. Following CSch's clear instructions on Dualbooting Windows 7 And Linux Mint 12 - Page 2. Have used Win7 to create space, boot from my Mint12 disk, get to 4th Screen down on page 2, "Installation Type", and don't see third option, "install Mint12 alongside Window". Only have two options, it is as if the Mint installer doesn't see the Win7 partitions on the disk. I think I have followed instructions. Would greatly appreciate any suggestions as to what to try next. Thanks.
