Hi guys, I was playing with Grub2 conf files and had a few issues:
1) At boot grub loads the menu but there is no timeout, it just sits there waiting for me to press enter
2) I was not able to put a special menuentry as separator between ubuntu entries and windows entry: it shows in grub.cfg but doesn't in the boot menu...
can someone please help me figure out what the problem is? thank you!!
here are my configuration files:
/boot/grub/grub.cfg
