I recently upgraded from my asus Mobo to a foxconn board because i needed a PCIx16 slot for my graphics card and, at first everything went fine, went into BIOS and set time/boot options etc but then when i went to boot it comes up with SYSTEM DISK ERROR. PLEASE INSERT BOOT DISK AND PRESS ENTER. My HDD that i'm using has XP Home installed on it. the PC worked before i changed board, and the new board is full-size ATX with 24-Pin Power socket, the power supply i'm using is 20-Pin. i found out it will work but i don't know whether this is the problem. the jumpers/connections are all set-up properly but if i don't get the above error i get a Disk Read Error, or no boot at all. Could it be because of the Power supply? or could it be a HDD problem? i need hellp on this.
