There is currently something wrong with my laptop and I have lost all functionality in normal mode and most in safe mode. So far here is what I have tried to do to fix the issue:
1. Boot in safe mode and try and format the C drive. I have tried doing this using the command prompt and also by right clicking the drive and selecting format. Unfortunately this has not worked as neither method recognises any of the drives.
2. Try to boot from CD/USB which contains a live Ubuntu CD/USB but it just boots into windows.
3. I tried to select the order of boot devices but it won't let me choose USB or CD.
There is nothing important on the hard drive so I don't mind wiping everything and starting again. Ideally I want to wipe the hard drive and install Ubuntu. Any suggestions on what I can try now?
