I wonder how many bytes grub2 puts into my hdd starting from MBR.
I found information, that core.img file is put after MBR (at 512 offset).
I found another information that kernel.img file is one of components of core.img.
But how can both be true if my kernel.img file is significally larger than core.img?
I'm asking because I use (with help of grub2tc) dual boot with truecrypted windows7 and truecrypt uses sector 63 (counting from 1) for it's volume header data. Grub2 overwrote this sector and I would like to get known if this area is realy used by it and if it is safe to re-overvrite it again with truecrypt original sector as described here:
