When you're multi-booting (more than one OS per system, as opposed to dual
booting, which is exactly two operating systems per system), it's nuts to do
it any other way. Putting Grub on the MBR is license for Windows to drive you
even more nuts than normal.

You don't need to bother with grub4dos. dd can make a copy of your root or
boot partition's partition boot sector as a file. Copy that file to the
Windows boot partition (C:\), put a stanza for it in boot.ini, and ntldr will
offer it to you in its menu.

Disks typically vary in speed according to physical sector position on disk.
Usually the lowest numbered sectors perform best. The tail of the disk is
usually the worst place for swap. If Linux performance matters to you, don't
put Windows at the front if you can help it either. C: can be the 2nd, 3rd or
4th primary if you take the trouble to make it so, usually easiest by doing
100% of your ultimate partitioning in advance of any OS installs.

All that means is there are only 2 primary partitions on the disk. XdX1-XdX4
are always reserved for primaries, no matter how many actually exist. The
first logical is always #5, though the primary starting at the front of the
disk isn't necessarily always #1.
