What AMD driver is compatible for Windows 10?

Microsoft just notified me that I can reserve my free windows 10 upgrade. But when I checked my pc, it said that my AMD Radeon HD 8400 and my Bluetooth Audio Device might not work with Windows 10. Uhm, can I install another driver that will work with windows 10? Or this driver is like, permanently installed in my computer? Help me please. Thank you.

PS. My laptop is Lenovo Ideapad.

Added (1). Is there any possibilty that I can upgrade windows 8.1 with windows 10?

No just use windows xp

They might not work, correct.
HOPEFULLY, Lenovo or AMD will bring out the correct driver over the next month so that they WILL work. Otherwise, you will be complaining bitterly to them and they won't like that.
