After installation of Linux distro alongside with Windows 10 or other Linux distro, the GRUB boot menu will appear for you to select the operating system on every startup. Set the main option to be highlighted as your primary operating system at every first boot is definitely useful.
First of all, know what are the options available in your GRUB menu. Let's say if the GRUB menu looks like this:
- Ubuntu
- elementary OS
- Advanced options for elementary OS
- Windows 10
Open Terminal,
- Type sudo nano /etc/default/grub
- If you want Windows 10 to boot by default, look for the line GRUB_DEFAULT=0 and replace with GRUB_DEFAULT=3
- To save the file and exit, press Ctrl+O and then Ctrl+X.
- Update GRUB by typing sudo update-grub
- Done. You may reboot and see the changes in GRUB menu.
If you want to boot elementary OS by default taking the options in the GRUB menu above mentioned as example, replace GRUB_DEFAULT=0 and replace with GRUB_DEFAULT=1. The entry options are starting from 0 to 3 in sequence.

ReplyDeleteHow to boot a Mac from USB media
ReplyDeleteGetting your Mac to load from a USB drive is fairly straightforward.
Insert the USB boot media into an open USB slot.
Press the Power button to turn on your Mac (or Restart your Mac if it’s already on).
When you hear the startup chime, press and hold the Option key. Holding that key gives you access to OS X’s Startup Manager. Once the Startup Manager screen appears, release the Option key. The utility will look for any available drives that include bootable content.
Using either the pointer or arrow keys on the keyboard, select the USB drive you wish to boot from.
Once selected, either hit the Return key or double-click your selection. The machine will start to boot from the USB drive.ds emulator jiofi login
