Been everywhere trying to figure out this problem. Emachines ET-1831-03 box, with Intel ES-300 dual core 2.6 ghz processors,. Ran fine, then SATA Seagate 750 gb HD failed. Received the correct system restore CD's from both emachines and Asus. Attempted to reinstall Windows 7 home Premium 64 bit on alternative 80 gb WD IDE hard drive (having removed the defective 750 gb Seagate Barracuda 7200.11 from the machine). Also installed 2 gb DDR2 which tested fine, to insure no RAM errors. Recovery CD's go thru entire restore process, and say to remove the last CD and restart. On restart - I get only the black screen with the "MBR01 Error" message.
RAM has been tested. Obviously the motherboard and CPU are OK, because it loads the system CD, and does the complete recovery install process. I am a retired IT professional, and this is the first time I have been stymied by an operating system re-install. I've tried variations in the BIOS settings for about 10 tries, with the same negative results. What am I missing?
