Installed 5.10 Today and Windows is not in the GRUB menu

[Dotan Cohen]

I have two hard drives- hda and hdb. Windows is installed in a
partition on hdb and until this morning was the only OS on this
machine (I know that is unusual. That is the situation after an
earlier attempt at Fedora). When I installed Kubuntu to hda today I
changed the BIOS setting so that the machine will boot from hda. But
Windows is not in the GRUB menu. What must I do to make it be there?
I'm pretty sure it's hda8 but I could be wrong.

Thanks in advance.
