Dual boot from 2nd drive

I purchased a new ACER with Vista Home Premium.

Put the old drive with XP Pro - both SATA drives - in the new computer.

I have re-installed some of my programs to the new drive but still have about 2 dozen on the old drive.

My problem -

I can get to and use my data from the old drive - and have also tnx my data to the new drive as well - but can't, of course, use any of the old programs.

Can I set up a dual boot to the XP drive? (I have tried to boot from it but it won't do so?)

If not, is there any way other than re-installing all my programs to the new drive? (I have seen something about cloning a drive but don't, of course, want to clone everything to the new drive.)

Tks for your time and have a great day - jb
