Everything should work fine until you upgrade Windows, a process that will mess with GRUB, causing you to lose the GRUB menu. To restore access to your Linux Mint 10 installation, the recommended solution is to install EasyBCD, a free application by NeoSmart Technologies, which you may download here. Install it just like any other Windows application.
When you first launch EasyBCD, the View Settings window will be in focus, and it will show an entry for Windows 7. First step is to add an entry for Linux Mint 10. To do that, click on the Add New Entry tab.
This is the default setting, but you will need to modify it to reflect the version of GRUB used by Linux Mint 10.
Since Linux Mint 10 uses GRUB 2, select it from the dropdown menu and click on Add Entry. You might want to modify the Name field.
Now, every time you reboot the computer, you will be presented with the Windows Boot Manager as shown below.
