    Hi jaranya8 and others,

    My dual boot problem is related to the fact that I had TWO separate PCs---one with XP 32 loaded and on the second PC I had XP 64 loaded. They were on separate computers but now in one computer.

    I took the hard drive with XP 32 out of one PC and placed it in the PC where XP 64 is on its own hard drive. So, I wind up with a PC cabinet with a different operating system on each of the two separate drives.

    The two drives are both SATA drives and they are setup correctly and I can access both my hard drives from the one PC. It boots automatically to the XP 64 drive becaue it was there first BUT I don't know how I can tell the PC that I want to boot to the XP 32 drive when I want to use that drive.

    The question is: How do I make it into a dual boot system when the operating sytems were installed initially on two separate hard drives on two different PCs and then I took the XP 32 hard drive and placed it into the box with the XP 64 on a separate hard drive which it only recognizes right now.

Ok, I expect that you don't really want to re-install a windows system on one of the drives to accomplish this. For one, you may lose saved files. What you need is to install a boot manager. See It looks to be free, downloadable, plenty of support information, and just what you want.
If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

So you want to merge those to make it as dual boot system on one harddrive, right? Try these steps:

1. Go to start, control panel
2. Performance and Maintenance
3. Administrative Tools
4. Computer Management -> expand storage, click Disk Management
5. Right Click the drive containing XP32 that you want to use, click format... Choose NTFS then make it as Extended Partition.
6. Reboot your computer and try to see by Pressing F8 if there's an option of what operating system you are going to use.

*Drop me a comment if that works or not so I can assist you further.

The setup is as straightforward as any dual boot situation. Pop the CD in and reboot. The system should boot to the CD, and installation will begin. You will be prompted somewhere along the line where you want the OS to reside, with which you will just pick the drive letter of the other physical drive. The system should install the OS no problem, and upon reboot you should get a selection screen after POST asking which OS you'd like to start. By default, if no selection is made within 30 seconds, it will go to whatever one is highlighted.

You need to start with a fresh, fully formatted hard drive (which also checks the physical surface of the drive for errors). Don't choose fast format. Insure that you have enough free space on the partition or hard drive.

Memory confusion different readings

It sounds like something isnt working right, what operating system are you using, Vista? I would take out the original 512 and see what it says after, often ram isnt compatible if it is too different in size and speeds. Also, if your motherboard supports dual channel ram and you have the extra 512 chip it wont run in dual channel mode, you would run better with just the 2 chips then the added 512 chip.
