Hey, sorry if I missed this but I had a good look around at a few threads too... I can't find how to totally get rid of some entries:

My PC had 3 OS partitions BEFORE Ubuntu:
Vista (Install, the first thing when the PC was turned on)
Vista (OS)
XP Embedded

So my grub has these three in addition to the two Linux entries and the memory tests (which got disabled)

I want to get rid of the Vista Install and the XP Embedded from the menu alltogether, like I could very easily on Grub.

Is this at all possible...?
