Would be nice if CTM would also be able to restore the BCD. Then CTM could be used to recover from a /Boot/Bcd error on Vista and Win 7 machines. Currently it looks as if CTM does not include the BCD in the snapshots (not even in the baseline).
Sadly /Boot/Bcd errors do often occur on Vista and Win 7. The only way to recover from it is by using a windows setup or windows RE CD, but netbooks don't have a CD player and most netbooks are delivered without a windows CD.
As far as I know, the bcd is just some hidden system file that windows uses during pre-boot state, though i might be wrong in that assumption.
