There was no /etc/default/grub file, so how come my system was able to boot?
I'm running Ubuntu 13.10. I wanted to change the GRUB timeout by editing the /etc/default/grub file. But there was no such file in my system.
On startup the GRUB menu is displayed and I'm not experiencing any boot problems. If this file was so important for booting, why am I nit experiencing any boot problems?

Do you have this line in /boot/grub/grub.cfg### END /etc/grub.d/00_header ###? if so, you could try addingset timeout=-1just ahead of that line. If you want a short time out use 2 or 5 instead of -1. That is where timeout is in my .cfg file

Reinstall the package and hope for the best:
sudo apt-get --reinstall install grub-pc
Actually the file is not critical for the boot, just to configure the boot when you execute sudo update-grub. If the file doesn't exist, then all values are default ones, like you didn't set them up.

Do you have this line in /boot/grub/grub.cfg
### END /etc/grub.d/00_header ###? if so, you could try addingset timeout=-1just ahead of that line. If you want a short time out use 2 or 5 instead of -1. That is where timeout is in my .cfg file– user3121023
