# Boot Management
|
|
|
|
## Bring up the boot menu with no timeout set?
|
|
|
|
By default, EFI installs will not show the boot menu and boot directly into Solus. By hitting space bar (repeatedly) during boot, the boot menu will appear (it may take a couple of goes to get the timing right).
|
|
|
|
## Appending kernel parameters to Solus boot
|
|
|
|
Kernel parameters can be appended to boot via creating a file for `clr-boot-manager` to use when updating kernels. For example, to add `nomodeset` to boot options, you would create the file `/etc/kernel/cmdline` (as sudo):
|
|
|
|
```
|
|
echo 'nomodeset' | sudo tee /etc/kernel/cmdline
|
|
```
|
|
|
|
The settings should be on one line with a space between them. You will need to run `sudo clr-boot-manager update` for the options to be appended to boot.
|
|
|
|
## Displaying the Solus boot menu by default on boot
|
|
|
|
The following command will set the timeout of the boot loader so that it appears by default.
|
|
|
|
```
|
|
sudo clr-boot-manager set-timeout 5 && sudo clr-boot-manager update
|
|
```
|
|
|
|
## Installing an alternative kernel
|
|
|
|
By default from `Solus 3`, the ISO ships with the `linux-current` kernel. The separate kernel branches can be added by installing the `linux-lts` or `linux-current` packages. Note that each kernel has separate module packages, so if you use these kernel modules, you'll need to install the one related to the kernel you are adding.

### Change the default kernel branch to boot
|
|
|
|
After successfully booting into a kernel from the `current` or `lts` branches running `sudo clr-boot-manager update` will make the booted kernel branch the default boot option going forward.
