Using the Gateway recovery disk that came with my computer.

The following window has came up:

• /ini f - get string and settings from INI file f
• /disk n - use physical drive n[1..9]
• /stealth - force installation of the one sector MBR that hides the SmartImage partition in stealth mode

• /active n - activate partition n [1..4]
• /r - force recovery boot on next system start
• /s - force service boot on next system start
• /u - force user boot on next system start
• /b file - save backup of old MBR to file
• /mbr file - get new mbr from file
