customise dual boot screen

[stereo]

Is it possible somehow, to customize the dual boot screen ( Windows 7 / Windows 10 ) ?
Something like this, but without a third OS

Hi Stereo,

I was looking at the documentation of Berg and Grub (Which Berg is based from) and there doesn't seem to be a way to specify a windows directory from the ChainLoader.

My first thought about this is to create a new (primary) partition for e.g. your Windows 7 folder and then create a new Grub menu entry for that, but pointing instead e.g. to (hd0,1) rather than (hd0,1).

On the windows 7 partition you can change the directories for My Documents etc. so that they remain shared between the two OS's.

I hope this helps in some way!
