Hello,
In Windows Vista, even though you are logged in as an administrator, the
programs you run are only given "normal user" access to your system. You
must explicitly authorize a program to run with administrator permission.
To do this for command-line programs, you need to open an "administrator"
command prompt, and then any program you run from that command prompt will
have the administrator permission you need.
- Click start
- Type: cmd
- Right-click cmd when it appears under Programs
- Click Run As Administrator
You will then be able to run bcdedit or any other administrative tool from
within that command prompt
