FreeDOS should not really care about that, but it will try to load first fdconfig.sys and if that is not found config.sys from the first primary visible FAT partition... Because Windows does not care about fdconfig.sys, you can easily let it share C: with FreeDOS for that one file. The kernel of DOS could be on another drive or on the same but the latter requires a boot menu which can either load our kernel directly or which can keep multiple (Windows, DOS) boot sectors, for example stored as files, available to pick from. > that DOS had been put on an extended partiton and still would not The boot sector expects partition location (a field called hidden sector count for no intelligent reason) to be absolute, which is not the case for extended partitions. A boot sector or boot menu which works around that (e.g. patches the boot sector in RAM when you pick that menu item) can make DOS able to boot from extended. > boot.

As far as I remember, GRUB contains a relatively powerfull shell. While it might not be enough as permanent fix, it should be enough to temporarily fix your states far enough so that you can boot and then use Windows or Linux to repair the rest. Also, I would think that Linux should not care about whether it uses hidden partitions. For example you can use the "edit menu item" feature in GRUB to do things like (un)hiding and telling GRUB what and from where to boot "this time" before you launch a menu item.
