windows 8 - Dual boot disaster. Professional help needed

I've had a disaster and need professional help.

To establish if I have lost Windows 8 entirely from No1 disk, this was professionally installed by the local Microsoft dealer, along with a second (new) solid state 250 GB hard drive for the 12.04 install.

I installed 12.04 to disk No2, after ensuring I had the "boot order" correctly sorted and found No2 disk with no operating system on it. But something went wrong and it installed onto disk No1.?

I found I had problem after I ran Boot Repair, as Windows 8 did not appear in the Ubuntu start up menu. 12.04 appears to be working 100% on diskNo1.

I also ran the unistall part of the Boot Repair programme, according to that there is only 12.04 on the disk.

Though; looking at the Disk Utility programme, there are two 8.5 GB partitions, one says "extended", and the other says "unknown". Could Windows be in the unknown partition?

Is there a specialist in or around the Stevenage area, (Hertfordshire UK), who could do the necessary repairs and upgrades to my Cruz Microsystems, model itx system.
