First, I meant to say "Can't I boot into Ubuntu". I installed Ubuntu into my laptop for the second time after wiping the partition from the first one. I don't know if it is the newest Windows update but the Grub menu doesn't show up anymore when I power it on. It was a couple of days ago, but not today.

I tried going into Ubuntu through the USB I installed off of and changing the boot order through efibootmgr, but it didn't work.
I go into the BIOS but the Grub boot menu is not even an option on the list.

I just want the Grub boot menu back.

I am using an Acer Aspire E5-575G-562T with UEFI BIOS.
Please help.

I assume GRUB got replaced by Windows's bootloader? If so, then boot into a Linux Live disk (does not have to be Ubuntu; any Linux distro is fine). Then mount your Linux partition. Then run grub-install on it.

Example, if you mounted /dev/sda to /mnt
# grub-install --root-directory=/mnt /dev/sda

Obviously, that's an example. You should modify that command to whatever your mount is. Also, you need to run this as root (or via sudo).

What would I type into terminal to do that, assuming I installed in /dev/sda2?

Would I be able to have that be there when I turn on the laptop, like with the GRUB menu?
