which is exactly why messing with bootloader should be left to the OS installed (which in this case is a very good one).
windows boot loader is not destroyed but grub is installed in front of it. can easilly be resoterd to previous setting if that is necessary. one command is run from windows install CD and the windows MBR is again in the first position (grub is gone). actually the one that destroy the boot loader is windows MBR.
my point is that
1 - linux mint does not require formatting of whole disk but rather you need only a portion of disk (partition) to be formated in linux file system
2 - it does leave windows OS alone. completely.
3 - as mentioned you can install grub to linux partition however then you need to change the boot order manually in BIOS. while htis way boot comes up you select the os oyu want and you go... you can also install boot loader to a floppy disk if you like and then select to first boot from that.
an option exists called mint4win which installs the operating system inside virtual disk that is inside widnows and can later be removed form the system like any other windows programme. i believe it uses windows boot loader to load grub. however it has some significant shortcomings compared to side by side install. have a lok here on how this looks in Ubuntu (on which Mint is based):
