Trying to install a fresh copy of Windows 7.

My computer lost data for some unknown reason (not there was anything important stored). Now I'm trying to install Windows 7 through a flash drive but after the splash screen it shows a black background with a small, white, vertical, flashing line.

Did you use Microsoft's tool?

This tutorial works.

Follow that tutorial. It is a bit more involved but works.

Nevermind, it works now. I changed the boot priority, making the USB Sandisk on the #1 spot instead of the HDD.
