In my SY-KT333 Dragon Ultra Pt./AthlonXP 2100 I have replaced a failed Maxtor 30 with a new Maxtor 30. On boot I get the message "NTLRD missing" and instruction to restart. I have tried booting directly to WinXP disc but get the same message. I built machine last Feb. and have not flashed BIOS. In Feb. I booted directly to WinXP and got smooth install and subsequent good service. With this new HDD I used the Maxtor instal. disk, followed instructions and subsequently tried all remedies in th instr. book for this boot problem problem. Any assistance will be greatly appreciated.
