\"Grub\"<\/p>\n

After installing recent updates in my Ubuntu 18.04 via Software Updater, Grub2 boot-loader menu is not showing on startup. The dual-boot (or triple-boot) operating system is no longer available<\/b> when you press Shift<\/code> (or Esc<\/code>) to show the menu entry.<\/p>\n

It seems to be a grub2 package issue in the recent update, though I’m not sure. And sudo update-grub<\/code> can’t detect operating systems outside the current Ubuntu release.<\/p>\n

\"\"<\/p>\n

If you happened to have the similar issue, try following steps to fix the problem.<\/p>\n

1.)<\/b> Open terminal<\/u> and run following commands one by one to install grub-customizer<\/a>:<\/p>\n

sudo add-apt-repository ppa:danielrichter2007\/grub-customizer\r\n\r\nsudo apt update\r\n\r\nsudo apt install grub-customizer<\/pre>\n
For Ubuntu 19.04<\/b> and higher, grub-customizer can be easily installed from Ubuntu Software.<\/p>\n
2.)<\/b> Launch Grub Customizer. When it opens, do:<\/p>\n
    \n
  1. navigate to General Settings<\/b> tab.<\/li>\n
  2. check the first two check-boxes under visibility to show menu, check for other OSes.<\/li>\n
  3. click on the Save<\/b> button.<\/li>\n<\/ol>\n
    \"\"<\/p>\n
    3.)<\/b> After saving the changes, navigate to ‘List configuration<\/i>‘ tab, and click on Refresh<\/b> button.<\/p>\n
    \"\"<\/p>\n
