Question

Lap only boots to startup config screen (safe mode/last known good etc. won't go to any of these - just keeps rebooting.) Tried the xp floppy boot disc (on ext. drive) & GET THE SAME RESULT.Don't know how to get to recovery screen (if it has one !)tried F10/11 However,it will go to BIOS screen. I don't have the original disc to reformat the drive & I can't see any support button on the Evesham site to get one.Can you advise, Many Thanks, icebreaker
