  | At least can anybody advise if I can mark the partition active from

Yes, fdisk can do that.

  | Would "fdisk -B wd0" give me the option to select a bootable partition?

Yes.   Just do that and install the bootselector, and you'll be back to
dual boot.

  | Is it safe to use fdisk on a Windows partition?

Yes.   Fdisk only modifies the MBR, that can (were you to do it) alter the
position of a partition (any partition, including the windows one) which
would effectively destroy it (unless you restore the old values).  Aside
from that, fdisk and partitions are orthogonal.
