Hi,I am new user of MSI note book that just buy without include OS,I try to set XP to it.at the first I follow the instruction to set up window,that I must first is to use in comand dos by using fdisk,after that I delete the primary and try to devide drive in to 2 part,but after I finish it,I forgot to set active partition, so after I reboot, I can't use dos like before and I see only the black screen with message "no active partition found"....Now my problem is that I can't use comand dos.My question is that : Is there any way to get back the dos to use command again,if now I can use only BIOS.
