Hey i'm having trouble booting to Ubuntu. Please bear with me it's my first time posting here.

I was going through a couple of tutorials on speeding up your system and edited one of the values in the grub file located /etc/default/grub

Now the GRUB_TIMEOUT is set to '0' and when I start up my laptop it goes to the default os boot menu which is Ubuntu. But it boots to Windows instead of Ubuntu which makes it very difficult to fix from Windows.

I have downloaded ext2explore to change the value which I can do but I can't update the grub so it doesn't work.

Thanks for any help or suggestions.

Try to run Ubuntu from a DVD or USB and use the program "Boot-Repair". That should fix the GRUB for you.
