## Booting with a Previous Kernel

If your system fails to start after a kernel update, you can try booting with an **earlier kernel version**. Here’s how:

### 1. Boot into GRUB

Turn on your laptop and **repeatedly tap the `Esc` key** as it starts up.

Stop pressing it once the **Star Labs logo disappears** — this should bring up the GRUB menu, as shown below:

### 2. If You Press `Esc` Too Many Times

If you see the screen below, you’ve gone one step too far.

At the GRUB command line, type:

`normal
`

Then press `Enter`, and tap `Esc` again until the menu appears.

If that doesn’t work, simply **restart the laptop** and repeat step 1.

### 3. Select a Previous Kernel

Use the **arrow keys** to highlight **“Advanced options for Ubuntu”**, then press `Enter`.

You’ll see a list of available kernels.
When troubleshooting, it’s usually best to choose the **oldest version** (listed near the bottom) — just make sure to select one **without “(recovery mode)”** at the end.

### 4. Boot the Selected Kernel

Press `Enter` to start your laptop using the kernel you selected.
