Unidentified network- limited connection after installing windows technical preview (Ethernet)

[Sickdog2009]

so recently I had installed Windows Technical preview (Windows 10 beta) and rather than giving me the ISO to dual boot with Microsoft decided to just install the damn thing for me :/

Upon downloading windows 10 preview I had noticed that my network driver was still applied regardless I had done a windows format (Broadcom Netlink Gigabit Ethernet). This then meant that I had seen an exclamation mark on the network symbol and upon diagnosing the problem, it comes back saying the ip configurations are wrong. So I decided to format back to windows 8.

Despite absolutely erasing my hard drive completely using a data destruction disk completely wiping out the hard drive, when I installed windows 8, again I was faced with the same error. How it managed to get the drivers to function the Ethernet I don't know usually I would manually install them on windows 7.

I have tried resetting the ipconfigs but still no luck. I can go back to windows 7 but I preferably want to stick with windows 8 for now just for the faster performance

This problem has never happened before and has only just started after installing the tech preview!

Also as a side question when I install windows 8 it will show on the desktop in the corner "windows 8 pro build 9200" does that mean I am still considered a developer after installing the tech preview.

I downloaded the .ISO file and made a windows 10 disk with out issue. I did not tell it to update my system.
I then pulled my hard drive and popped in a old test SSD drive and did the windows 10 install. Worked well except they did not have the default drivers for my motherboards Ethernet drivers. I had to provide them.

anyway, back to your problem. I would guess you would have to also provide your own network drivers unless you had a older mainstream Ethernet chip.

as to having info from your previous wipe show up. If that it the case I would suspect the information is stored in the reserved partition of your hard drive.
You would remove the partition and recreate it to wipe it out.

after you have already installed the older windows 8 partition I would suspect you can restore the old boot loader and files using the
bootrec.exe command

it has been a while but I think you start cmd.exe as a admin
run
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /scanos
bootrec.exe /rebuildbcd

sorry you may not need all of the commands but I don't think it will hurt anything if you run all of them and reboot your system
