How to Delete an Operating System Listed in Windows Boot Manager
I am facing problem in my laptop, I'm having dualboot of Windows 10 and Windows 7. I installed Ubuntu 17.04 in external HDD and using the same for few days. later I removed Ubuntu from external HDD but I am unable to clear OS Ubuntu boot option from Boot menu. I tried bcdedit command, used easybcd and msconfig but it is not getting removed.
Any suggestion for how to clear it.....
