Windows 8 unknown device found

Hi everyone,
So first I'll give you basic information about my computer and then I will tell you the rest. First my computer when bought came pre installed with Windows 7. As soon as Windows 8 came out I upgraded to Windows 8. My system is BIOS not UEFI. I have about 3gb ram and 500gb hdd drive 2.20 ghz processor. Windows 8 runs really smoothly. So recently 2-3 days ago I decided to dual boot Ubuntu with Windows 8. Before when I had Windows 7 I dual booted it with Windows 8. So now I thought about dual booting with Ubuntu 12.04 LTS. The Installation process was fine until I take out the installation usb with Ubuntu and whenever I try to restart it the PC would hang on the oem screen for a while which is ridiculously long. Then when I would boot into Windows 8 and sign in I would get a notification message saying the last storage device you plugged in isn't found. I went to the device manager in Windows and it would say an unknown device has been found and even if I tried to Uninstall it would come back again. I tried searching for updates but nothing came up. I googled it and got no results. If you guys can get me the problem solved it would be great. What annoys me the most is the PC hanging on the oem screen. Right now I fresh installed Windows 8 so it's the only OS running at the moment. But I want Ubuntu 12.04 LTS because of git, ssh and all the server side stuff. I have also posted the error screenshot for more info.

Thanks,

Gurinder Hans

I would take the ISO download and make a bootable DVD with it.

What software did you use to put the ISO on a bootable USB drive?

Hi there bassfisher6522,

Your system specs don't tell us anything about your hardware so I am just doing some guess work. Normally when you see an unknown device in the Device Manager that could be resolved by download and install the chipset drivers for your mother board. You might also want to check if your BIOS is up to date.

Hope this help.

Hey there man,

I have found the problem. For some reason my computer want detecting my webcam which slowed the boot up time. Right now I have took out the webcam from my pc so everything runs fine. All I have to do now is try to get the latest and right drivers for the webcam. :)

Windows vista and up are so finicky about permanently keeping your USB hardware in the same place.

But in the real world, we unplug stuff all the time and cant remember which of the 10 PORTS it came from!

You could always label your ports or cables. sounds daft I know but it works. I have cable tags e.g. webcam port 1, drive caddy port 2, mouse port 3 etc.

Anything for an easy life.
