I am new to this and was curious about running Ubuntu on my laptop running windows 10..
I couldn't not find the Grub menu after installing ubuntu so I went back into windows and found a so called hack...https://askubuntu.com/a/816347/970928
After doing following the steps I used ubuntu successfully from the Grub2 menu , now I wanna go back to windows but whenever I enter the Grub menu and select the option :
windows boot manager (on dev/sda1)
It opens the Grub menu again and again!!
What can I do to fix this guy's?
