Ubuntu only Boots after Booting Windows and Restarting

Question

I have been trying to get Ubuntu 16.04 to work on my computer alongside Windows 10. I followed the instructions for how to install it (I used the option to "install alongside Windows").

The Problem

The problem is really bizarre: When I first suspended Ubuntu and then tried to start up the computer again, it completely froze and I had to hard-reset the computer. Once I rebooted Ubuntu, it just loops forever with a blank screen and the "Ubuntu drum sound", occasionally blinking the login screen every once in a while.

My Attempts at Fixing it

There is one weird "fix" to this that I figured out; if I boot Windows 10, restart from there, and then choose to boot Ubuntu after the restart, then everything works smoothly. There seems to be something wrong connected to "booting the computer from after being turned off".

Another "fix" I had to do before discovering the above was to reinstall Ubuntu, in which case it works normally until I try to suspend it again.

My Question

Does anyone know what might be causing this? It is rather annoying to have to boot Windows, restart it and boot Ubuntu everytime I want to use it, let alone have to reinstall it.

In case this is helpful: I tried to install to Ubuntu 18.04 instead, but I receive similar problems -- the system breaks after trying to suspend, locking me at login.

Thanks in advance!

your graphics card might be causing this.

try to enter into ubuntu with "nomodeset"

1. when you see the grub, highlight to "Ubuntu" and press e to edit the kernal parameters.
2. go to the line starting with "linux" and find the string ro quiet splash
3. add the text nomodeset in between "ro quiet splash". now it should look like this ro nomodeset quiet splash
4. press Ctrl+x or F10 to boot.
5. Once you enter into Ubuntu.. try to install the rite drivers for your graphics card.
