hello i burnt a cd of 2010 beta but when i boot from my windows 7 ultimate it asks for a login which i say guest and password guest but it comes up with ls $ and i do not know what to put,should i burn another cd?
I don't quite understand what you mean when you say you boot from your Windows 7 ultimate?
Are you sure your booting from the live cd?
You must set the boot options in bios so that your cd/dvd drive is the 1st bootable device.
If you've done that,added guest and guest for username and password then perhaps your disc is faulty.If so try burning another disc at a nice slow speed around say 4x.
Hope this might help.
