So I downloaded windows 10 yesterday, as soon as it was downloading the log-in would just flash, I couldn't do any thing so I had to shut the computer down. When I tried to turn it back on it brought up a blue recovery screen that said that your PC needs to repaired. The boot configuration data file doesn't contain valid information for an operating system. I contacted dell they sent me a usb drive with windows 8. I tried to reinstall windows 8. But it won't work. When I click on repair your computer, then click on reset your pc. That says unable to reset your PC. A required drive partition is missing. Please help I don't have the money to have dell help me, they want $129 just to help once.
