FIrst check if the partition of FreeDOS is still set as "active". Multiple OS on one disk doesn't install automatically any form of dual boot and Gentoo is one of the rather peculiar Linux distros. You also might check into installing GRUB or any other boot loader from your Linux distro. If you just want to get FreeDOS back up and running, try running FDISK C: /MBR from a FreeDOS boot media (floppy disk or CD)...

Re: [Freedos-user] How to reinstall FreeDOS VBR?
Hi! If you want a fresh boot sector for your DOS partition, you can simply run SYS C: on the DOS prompt after booting from another medium. You could also use a tool such as my sys-freedos-linux, which uses Perl and NASM to write a boot sector to a given disk device or disk image, but because it does has no access to the geometry and location of disk and partition, that would be more complicated than using SYS in DOS. While SYS also copies kernel and shell, you can use the suitable command line options for SYS to suppress that if it really is a problem for you otherwise. You can even tell SYS to write the boot sector to a file which you can then use in any way you like, for example in special boot loaders/menus. I am surprised that resizing failed to update all necessary boot sector fields, though. It is not SUPPOSED to break boot.
