1. The Windows key is embedded inside the BIOS so you don't have to worry about losing it as long as you didn't change the motherboard
2. Depending on your Windows 8 version, if it's home, you can switch to Windows 10 Home. If it's Windows 8 Pro, you can switch to Windows 10 Pro
3. Install Windows 10 directly instead of Windows 8. Windows 8 is slow, outdated & has lots of issues
4. Refer to my signature on how to prepare a Windows 10 USB installer
5. Enable Secure Boot (if available) in your laptop BIOS
6. Disable CSM or legacy BIOS in your laptop BIOS
7. Enable Fast Boot (if available) in your laptop BIOS
