Never install grub's boot sector to a partition, install it to the mbr
instead (/dev/sda).

Never unless you care to be able to _easily_ get your Linux back after reinstalling Windows. IOW, it doesn't matter where Grub is installed if Linux is the only installed OS, but may matter a lot if you're multibooting.

If you don't put non-standard boot code (e.g. grub code) in the MBR, then you don't create a(n unnecessary) dependence on it that _will_ be broken by (re-)installing Windows. When Grub code is in a primary partition's boot sector instead of the MBR, then standard MBR code will launch it automatically simply from the presence of a 1 bit flag in the master partition table. Installing Windows will merely move that flag to a Windows partition's table entry if the MBR remains standard. Then after installing Windows it is sufficient, and quite simple, merely to move the flag instead of having to reinstall Grub when you want initialization to begin with Grub rather than NTLR (which can be configured to load Grub from its boot menu).
