Keep reading. I explained how to know below.

I take the line where "Mounted on" is /. That partition or
"Filesystem" as in the listing above is /dev/sda3. In your
case, it is /dev/sda6. Removing the trailing number that
means the disk where you want to install grub is /dev/sda.
Here is what all this means. All "devices" on a Linux or
Unix system are always listed under the /dev folder. For
example a floppy device would be listed as /dev/fd0 or
/dev/fd1 etc. fd0 would be the first floppy drive and fd1
would be the second. /dev/hd* is for IDE or ATA devices.
The first would be /dev/hda, etc. The first SCSI device
would be /dev/sda. When SATA devices came along, the
powers that be in Linux decided just to use the SCSI device
designation. The first SATA device would be /dev/sda.
Partitions on a device are listed with a trailing number.
For example, on your system, Xubuntu's / is on partition
6 listed as /dev/sda6.

Yes, so long as we are talking about the latest version
of each. In fact I do exactly this.

Absolutely you can do this later. I understand running
before you walk. I started out keeping everything Linux
under a single partition. When I found out from suggestions
on this list that keeping a separate data partition would
be a good idea, I incorporated that in my next install.
My suggestion would be that you might want to do this
the next time there is a Xubuntu upgrade.
