I have dual boot Windows 8.1 and Ubuntu 14.04. When Ubuntu installed GRUB, it created two entries for Windows 8.1, one for /dev/sda1 and one for /dev/sda2.

How do I change the boot menu entries to remove the redundant choice? Also, how do I extend the boot menu delay time?

  • Are the entries identical? Often, you will see entries for each partition (recovery partition, main Windows partition, sometimes it will even setup GRUB so you can boot on other partitions). They will appear as sdax where "x" is a different number for each partition. – fixer1234 Feb 12 '15 at 9:33
  • both the entries are on different partition.It is showing Windows 8 (loader) on dev/sda1and Windows 8 (loader) on dev/sda2. – Aravind S Feb 13 '15 at 11:12
  • One is probably the hidden system partition. See this: askubuntu.com/questions/280026/how-do-i-hide-an-entry-from-grub – dkanejs Feb 13 '15 at 19:57

The GRUB can be modified using an GUI application called the GRUB CUSTOMIZER .

To install GRUB CUSTOMIZER follow the below steps-

  • Open Terminal
  • Type the following command: sudo add-apt-repository ppa:danielrichter2007/grub-customizer .This PPA contains the latest release of Grub Customizer and adds a repository for Grub Customizer .
  • Next update your repositories by typing :sudo apt-get update , since a new repository has been added.
  • Next download the grub-customizer by typing : sudo apt-get install grub-customizer.
