I found the answer with another search. I turned off tpm and was able to install without without bitlocker
When i installed windows on an unlocked new drive it came up as bitlocked drive in disk manager after install. I removed the drive and cleaned it in another computer. I want to reinstall windows 10 without bitlocker so I can dual boot another operating system.. Is there something in the BIOs hard drive security that will allow me to do this?
