Introduction
When booting up a computer, it is common to see a series of startup messages before the operating system (OS) loads. These messages can provide valuable information for troubleshooting and debugging, but they can also be overwhelming and confusing for the average user. Many OSes have the option to hide these messages during boot, but there may be situations where it is necessary to view or disable these messages.
Windows
In Windows, the startup messages are controlled by the system's boot configuration data (BCD). To disable the startup messages, follow these steps:
- Press the Windows key + X and select "Command Prompt (Admin)" or "PowerShell (Admin)" from the menu.
- Type
bcdedit /set {bootmgr} displaybootmenu yesand press Enter. - Restart the computer and press F8 during boot to access the Advanced Boot Options menu.
- Select "Disable Boot Menu" and press Enter.
To re-enable the startup messages, follow the same steps but select "Enable Boot Menu" instead.
Linux
In Linux, the startup messages are controlled by the kernel command line. To disable the startup messages, follow these steps:
- Edit the GRUB boot configuration file (usually located at /etc/default/grub).
- Find the line that starts with
GRUB_CMDLINE_LINUX_DEFAULTand addquietto the list of options. - Run
sudo update-grubto apply the changes.
To re-enable the startup messages, remove the quiet option from the GRUB_CMDLINE_LINUX_DEFAULT line and run sudo update-grub again.
macOS
In macOS, the startup messages are controlled by the NVRAM (Non-Volatile Random-Access Memory) variables. To disable the startup messages, follow these steps:
- Restart the computer and immediately hold down the Command + R keys to enter Recovery Mode.
- From the Utilities menu, select "Terminal".
- Type
nvram boot-args="-v"and press Enter. - Type
rebootand press Enter to restart the computer.
To re-enable the startup messages, follow the same steps but replace -v with -x in the nvram boot-args command.
Disabling the hide boot startup messages can be useful for troubleshooting and debugging, but it is not recommended for everyday use. The steps to disable and re-enable the startup messages vary by OS, but they are generally straightforward and can be performed by a user with basic technical skills.
