I was upgrading my PC to windows 10. I don't have a windows installation disk or usb. I created a partition G and kept the setup files there and marked it as active. When I restarted the PC, a disk read error occurred. I still have a working OS on the C partition. Is there some way I can set it as active or just bypass the error?
