I've installed ubuntu alongside windows7 in laptop. When I restart after installation, it is directly entering Ubuntu OS. It is not showing the option which OS to choose. Windows is not deleted because I can access the files and other things that are in windows OS and 'disk usage analyser' is showing the assigned memory of ubuntu while partitioning. How can I fix this GRUB error.

while your system is turning on, press and hold shift until grub menu loads.

check whether grub lists your windows partition, if it didn't show, try updating grub by using

sudo update-grub

if still it doesn't work, use boot-repair

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
