 Installing a Kernel from a Repository
 ---------------------------------------
 
+:::warning[Important: Reboot After System Update]
+
+Before using Kernel Manager to switch or install kernels, make sure to reboot your system if you recently performed a system update.
+
+**Why?**
+- Running kernel might be different from the installed one after update
+- Switching kernels without rebooting can cause `mkinitramfs` failures
+- System might become unbootable
+
+**Recommended workflow:**
+1. System update
+2. Reboot when prompted
+3. Then use Kernel Manager to switch/install kernels
+
+**Tip:** Enable system snapshots (like Snapper) for quick recovery if something goes wrong.
