Hello, i'd like to do this on my y510p, however i cannot boot into windows at the moment. This means i can't/don't know how to backup my bios. I tried running the backup program by booting into dos from the usb and running the program, but that did not work. Any help that can be offered would be appreciated since this is the only step i cant do. Some background info; im 99% sure my discrete graphics card is done for, which is preventing being able to boot past the lenovo loading screen. I want to disable that gpu completely in the bios and only run the integrated graphics card because thats definitely working.
