I recently got a new computer and have been trying to upgrade from windows 10 32 bit to 64 bit. i am fairly certain i have done everything correctly as windows downloaded, however, when i try to boot from my new hard drive (the drive i downloaded windows onto) it just sits at a black screen with a white blinking dash. I have also talked to windows support for like 3 hours which didn't help and was a waste of time. please help!!
