I have an issue with windows 10. I loaded windows 10 before reading the Alienware advise that it wasn't compatible with the version of computer that I have and now window 7 that I had before isn't anywhere to be found on my computer due to me trying to get back to it and reinstating windows 10 instead which cleaned out all the programs it didn't like. I need a boot disk for windows 7 and for Alienware's running system as windows 10 didn't like that either. It seems that without a warranty alienware doesn't care about its older systems that aren't compatible with windows 10. Can anyone help? I have tried to reboot but window 10 is the only option.
If this does not work, you could always try a clean install of Win 10 that fixes most issues - http://bit.ly/1VxGDgb
If you choose to reinstall Win 7 on the system, since your system warranty has expired, if you are living in the US / UK, you could order the Dell OEM discs online - http://dell.to/12vcZ27 - this will include the OS disc and drivers / resource disc.
