Hi, Sandra -

You might want to read this post about using two drives. I used to do it Noel's way (going into BIOS and selecting which disk I wanted to boot from). I didn't have any problems with this.

When you do that, your boot drive will (by default) be the C: drive and the other drive will show up as the D: drive. This assumes there are no other partitions on either disk. So, if you boot to the Win7 drive, Win7 will be C: and you'll see the XP drive as D:. Conversely, if you select the XP drive to boot from, XP will be C: and Win7 will be D:. However, what I do once I get everything set up is to go into "Manage Disks" and change the drive letter of the non-booted OS to the Z: drive. That puts it in the bottom of the list and prevents me from accidentally selecting it and maybe deleting something important.

This method (as Noel said) avoids having a boot manager, which can work, but sometimes gets screwed up when Windows does updates. That's why I preferred Noel's method.
