Windows installation is very simple and works on Windows 2000 / XP, Vista and Seven. First, fetch the Windows installer from this link here and extract the contents to a folder.
Next up, run the program called “setup.exe”, you may receive a UAC prompt if running Vista or later. This is because the Raspbmc installer needs to run as an Administrator on your system to write to the SD card at block device level.
You will now be presented with an interface such as this:
Your SD card should be shown on the list. Simply check the checkbox and click Install to complete the installation. Note, if you have not inserted your card yet, you can do so now and click Refresh to update the devices list.
WARNING: This program enumerates ALL removable devices on the system, data loss can occur and I will not be responsible if you image the wrong device. It is recommended to remove all devices you are not imaging for safety purposes.
Note if you want to use your SD card for purposes other than Raspbmc and the card only appears to be about 60MB in Windows: That’s because Windows does not recognise the Linux partitions that Raspbmc uses. There is a simple fix for this though — rerun the Windows installer and click “Restore SD card for formatting”. You will now be able to see the full size of your SD card as a “Removable Device” for formatting in Windows. On new versions of Windows, you will be automatically prompted to format the device upon clicking this button. Simply format the device and your SD card can be used for storing content again.
