Sorry for the delay in replying.
I assume that as you have managed to get back into windows that you were able to restore the Windows MBR which is always the first partition on the master hard drive.
I cannot tell whether you have one or two drives but assuming that you are using a second drive. I always use the live dvd to partition the drive before starting to install Mint - gparted is used to achieve this. Obviously if you are using part of the windows drive then the same applies.
During the installation process, select the option to specify the partitions and set up your root partition (/), home and swap. The last time I installed Mint I used either LMDE or Mint 13 but in both of these at some point you are asked where to install grub, make sure that you select the windows MBR partiton which should be sda1. Once the install is complete your system will boot up with the Mint grub screen where you can select either Windows or Mint ( Mint will be the default selection). If you go to synaptic and install the program Startupmanager, using this will allow you to select which distro to boot by default and also the screen resolution and time delay.
On all my machines I have an ntfs partition which I use as a data store and this is an easy way to access and use the same information in both windows and mint.
If I can be of any further help do not worry about posting back
