Question

My computer is not starting and says there is no operating system. How I can reinstall Windows 7 with my CD?

Community Answer

Get into your PC'c BIOS by hitting DEL or F12 or F11 or F2. While the computer is booting up, then either select the CD drive, or go to boot order, and set your PC to boot from the drive. Usually it will tell you what key to press when it shows your PC's manufacturer while booting up.

Question

How do I rename a file with this?

Community Answer

Open the Command Prompt (DOS) and type in "RENAME [drive:][path]filename". Replace "[drive:]" with the drive the file is located in, such as the "C" drive. Replace "[path]" with the directory the file is located in. It should look something like "[drive:]WINDOWS\Users\user\Documents". Replace "filename" with the file you would like to rename.

Question

How can I change the color of the command prompt?

Isendrak

Community Answer

Use the command "color" followed by a two-character sequence specifying the fore- and background colors. For "Matrix-style" (green text on black background), it's "color 0a". For more information use the command "color /?".
