Windows 7 Ultimate x64 install cannot find Networking Components

I have a Toshiba P775-S7370 Laptop. It originally came with Windows Home Premium x64bit Sp1. I created a partition on which I installed Windows 8 Preview which is working fine with Networking and Internet intact. I wanted to install Windows 7 Ultimate x64 bit to replace my Windows Home Premium x64 bit. I did a clean install from a DVD in the DVD/CD Drive with booting enabled from DVD in the BIOS. The Program installed correctly except for the Networking. The node that should say Network Adapters now reads 'Other Devices' containg what it should have contained and all of them are not working. Network trouble shooting come up with 'Cannot detect networking components'. However the network card is Ok since there is a response to PING. Since Partition two is working an attempt to point the driverss location from the second partition comes up with the messaage' that it is not digitally signed and this version of windows requires digitally signed verssion etc. Where can I find the proper drivers?
Speedy PC Pro from Toshiba cannot access Internet where it is needed. I suspect it is just a trick to make the user buy unnecessaary software. In a new isntallation without internet connection the utility found few thousend problems (looks like a stretch). DeviceDetective from Realtek site cannot even start as the window complained that the package is not a windows installer pacckage.
Any help will be appreciated:

Sounds like you need to install the mobo and network adaptor drivers from Toshiba.

mobo? You mean mother board?

Thanks. Most of them are for Windows 8. Toshiba site was not very helpful. I finally found what works. It was a tortuous experience. I am documenting it and would elaborate in a day or two.

You can refine the search specifically to Windows 7, either 32 or 64 bit. Just click on the refine search by tabs.

The problem was solved. But thanks, I will do an Advanced Search. I remember I did carry out a more refined search.

Finally I was able to resolve most problems. Since the path I took is circuitous my explanations are somewhat detailed. The main difference I saw was that the Win 7 x64 ulitmate requires digitally signed files and the ones that came with the machine/software were not.

You could simply have downloaded a program like AIDA64 and had it identify the devices and then gone to the manufacturers website and downloaded the drivers. Realtek is among the easiest of all network adapters tpo get the drivers for. Windows 7 will definetly install non digitally signed drivers for devices

Agreed but it will also install unsigned drivers. They likely require installation in a different fashion.
It may not install them for every device but it definetly will use unsigned drivers in many instances.
