The typical steps for installing involves using a USB-bootable version of Debian and then partitioning the hard-drive for the new OS. Unfortunately, my BIOS has been locked and for various reasons, I can't get the password.
The current OSs on the system are: 1. Windows XP 2. Ubuntu 11.10
Someone told me that I could install Debian from within Ubuntu 11.10 but that would be "risky".
Could someone please help me with detailed step-by-step instructions on how to install Debian alongside Ubuntu when the only boot option is from the Hard-Drive, and not from USB or CD media? More details about the system will be provided on asking.
