How to boot Windows 7 from GRUB4DOS installed in the same partition?

Question

GRUB

There is a need to organize dual-boot with Win7. As far as I understand, if I install Grub4DOS on the same partition as Win7, it will overwrite the Windows bootloader. Is there any way to load it later from under GRUB? As I understand it, a banal chainloader +1 will no longer be enough and Grub4DOS will start calling itself cyclically.
But to put grub4dos, in my opinion, it's better to put it in this section. Or are there other better options?
