your xbox can't find the dashboard you are installing. (that's what error 13 is)
the duoX2 (blue, i'm guessing is what you have) with the switch on bank one (X2blue) will look for the file evoxdash.xbe in the root directory of a partition. (i.e. C:\evoxdash.xbe, E:\evoxdash.xbe, F:\evoxdash.xbe.
i can't remember which partition X2-blue boots from by default, but C:\ is a good bet.
don't install XBMC boot, that's where you're fucking up.
you need to edit your bios bootpath if you want to do that.
also note, that the flashing red light on the chip is a good thing.
it means the chip is working.
i suggest using FTP to set up your HD, rather than bullshit auto-installers.
if you boot with your installer disc, you should be able to FTP into the box. user: xbox, pass: xbox.
if your boot disc doesn't allow FTP, then it's bullshit. get slayer's or something like that.
i should also mention (for consistency)...you can install XBMC boot on this bios, but you must place all the XBMC stuff in a root directory and rename default.xbe to evoxdash.xbe, so you can try that also once you get your feet on the ground. start simple with evox.
