I am new to Raspberry Pi and I have downloaded the NOOBS setup zip file. I am using an HDMI to VGA converter to display contents on my monitor. It seems I need to edit the config.txt file to make it work. I have found the file in boot.tar.xz which opens using WinRAR. I am also able to edit the file using Notepad.

However when I save the file and open it again the edits are reverted to the original state. How do I edit the config.txt file?


  • Super user elevation is required to edit config. The boot partition should be fat32 and therefore readable in Windows. Or, while booted to your desired OS, CTRL+ALT+T for a Terminal window then input; sudo nano /boot/config.txt – Andy Anderson Nov 7 '17 at 8:33

Use 7-zip. Here's the download link: http://www.7-zip.org/download.html

  • Will it work? This page here says that XZ is not compatible with 7zip. – Dmitry Grigoryev Feb 16 '17 at 3:23
  • @DmitryGrigoryev Try it yourself. – PNDA Feb 17 '17 at 1:19

First copy the file to the desktop, edit it, then drag and drop it in the folder opened with WinRar.
