I have two desk top computers #1 is for the internet and #2 is for my work(consulting). #2 is never used on the internet I mean never. # 1 has an 80g hard drive with XP_PRO. #2 has an 250g hard drive with XP_PRO and a 300g slave. #1, the internet computer decided to take a permanent vacation and went south. So I bought a duo core computer with a 80g hard drive and XP Home. Let call this computer #3. I wanted to used the new computer #3 as my consulting computer( replacing #2). And then use #2 as my internet computer. I wanted to take the 80g hard drive with XP_PRO from # 1 and put it in #2 ( this drive has all my internet records- bookmarks, correspondent and I didn’t want to start over.) . I wanted to remove the 250g hard drive with XP_PRO and a 300g slave and uses them in #3 . The 80g hard drive with XP_PRO would not boot-up in computer #2. I was told this was caused by Microsoft. Is there a way to make this happen. What is wrong with Microsoft! Why must one go thru such pain to upgrade a computer or make a change in the hardware.
