I'm having problems upgrading to Windows 10; on the install part with the circle it reaches 70% overall and goes to a black screen with no cursor or hard drive activity. I have tryed installing five times now and have been reverted back to Windows 8.1 each time. I don't have access to error codes or pictures atm, I'm on my phone. Any help would be appreciated (i have intergrated graphics from intel if it helps)
