I'm new to Linux, and have had some trouble running and installing Ubuntu on my Windows 8 laptop for a dual boot. Here are some details about my computer:

  • OS version: 6.2.9200 N/A Build 9200
  • System model: 20246 (Lenovo)
  • System type: x64
  • Processor: Intel64 Family 6 Model 58
  • Network Adapter: Realtek RTL8723A

First, I created a LiveUSB with Linux 12.04, but when I ran the OS, my screen was too dim to see anything at all. If I held the screen at an angle, I could see something there, but couldn't make out exactly what it was. I plugged the computer into a television screen, when I found that the OS couldn't find any wireless networks, and that my mouse was acting kind of strangely (it would 'teleport' to the bottom left of the screen every 3rd or so time I clicked with it). I tried the same with Ubuntu 13.04, and had the same problems. Later, I found that when I plugged the laptop into a television screen, the laptop dimness would go away after the OS was finished loading. If I didn't plug it in, or took the plug out before the OS was finished loading, the screen wouldn't work.

Then I figured I could try installing the OS and see if that made matters a bit easier. However, after turning Safe boot off and partitioning the hard drive, I found that Ubuntu would not load after it was installed. I would see the GRUB screen, which asked if I wanted to load Windows 8 or Ubuntu. After clicking Ubuntu, it would tell me that Windows 8 could not load, and tell me file /nst/AutoNeoGrub0.mbr was missing.

Is there anything I can do to make Ubuntu work properly?
