How to Access the GRUB Menu in Virtual Machine
|
||||
======
|
||||
|
||||
Most modern VMs are configured to skip the [GRUB bootloader][1] for a seamless experience.
|
||||
|
||||
However, you might need to access the GRUB menu at times. For example, if you want to switch back to the older kernel or get into recovery mode for [resetting the password][2].
|
||||
|
||||
> 💡 Reboot your VM and keep the Shift key pressed when it is booting up again. This should give you the GRUB menu.
|
||||
|
||||
In this quick article, I will be showing you two ways to access the GRUB menu in Linux running in a virtual machine:
|
||||
|
||||
- A temporary solution (when you have to access GRUB once or twice)
|
||||
- A permanent solution (will show GRUB at every boot)
|
||||
|
||||
As most of the users are not going to interact with the grub on a daily basis, I will start with a temporary solution in which you can access the grub without any tweaks.
|
||||
|
||||
> 📋 I have used Ubuntu in the tutorial here but the steps should be valid for other Linux distributions as well.
|
||||
|
||||
### Access the GRUB bootloader in VM (Quick way)
|
||||
|
||||
If you want to access the GRUB occasionally, this is supposed to be the best way as it does not require any configuration.
|
||||
|
||||
Just reboot your system and keep the `shift` key pressed.
|
||||
|
||||
That's it!
|
||||
|
||||
You will have your grub menu without any time limit:
|
||||
|
||||
![Accessing grub menu in VM using shift key][3]
|
||||
|
||||
Pretty simple way. Isn't it?
|
||||
|
||||
But it will work for that specific boot only. So what if you want to have the grub on every boot? Refer to the given method.
|
||||
|
||||
### Enable Grub menu in virtual machines permanently (if you want to)
|
||||
|
||||
> 🚧 This method requires changing Grub config file in the command line. Please ensure that you are comfortable doing the edits in the terminal.
|
||||
|
||||
If you have to deal with the grub menu to access the other operating systems or change[boot from the older kernels][4] often, this method is just for you.
|
||||
|
||||
To make the grub accessible at every boot, you must make changes in the configuration file.
|
||||
|
||||
First, open the grub config file using the following command:
|
||||
|
||||
```
|
||||
sudo nano /etc/default/grub
|
||||
```
|
||||
|
||||
Here, change the `GRUB_TIMEOUT_STYLE=hidden` to the `GRUB_TIMEOUT_STYLE=menu`:
|
||||
|
||||
![change grub timeout style][5]
|
||||
|
||||
Next, in the same config file, specify for how many seconds you want the grub to be displayed.
|
||||
|
||||
I would recommend 5 seconds as it seems to balance between not too long and short (yep, quite relatable):
|
||||
|
||||
```
|
||||
GRUB_TIMEOUT=5
|
||||
```
|
||||
|
||||
![configure grub timeout in ubuntu][6]
|
||||
|
||||
And finally, you can [save the changes and exit from the nano][7] text editor.
|
||||
|
||||
To activate the changes you made to the config file, update the grub using the following command:
|
||||
|
||||
```
|
||||
sudo update-grub
|
||||
```
|
||||
|
||||
That's it. Reboot your system and the grub should be there for 5 seconds.
|
||||
|
||||
### How about theming GRUB?
|
||||
|
||||
You will get the grub bootloader in most of the Linux distros as it is quite simple to configure and gets the job done.
|
||||
|
||||
But by default, it's nothing apart from the black background and plain text. So we made a guide on how you can make it look dope:
|
||||
|
||||
I hope you will find this guide helpful and if you have any queries, let me know in the comments.
