Dual Boot Vista And Xp Without Disk

New To A Help Board... But Trying In Desperation As Cant Find Solution.

Got New Laptop But Only Could Get With Vista Not Xp. Some Of My Programs Wouldnt Run On Vista, And Vista Was Slower Than Xp, So I Would Like To Run Xp And Vista Together.

I Have Read The Tutorials Here, They Say Partition, Then Load Xp, Then Reinstate Vista For Booting, By Inserting The Vista Disc And Repairing.

Question.. How Do I Do This If The Computor Came With A Recovery Disc Only, Which Wipes My New Partion An Reinstals Vista Only With The Original Programs.

Question... Supose I Partition, Then Load Xp, And When Vista Dissapears Load A Commercial "boot Many Operating Systems" Will This Do It?

Miniquestion...when Make New Primary Partioin Do I Set It Active Then Instal Xp, Or Not Set Active And Let Xp Change It.

Miniquestion Can I Copy The Vista Mbr Before I Load Xp, And Copy It Back After? How?

Please Someone Help, (ps I Have Only A Vague Understanding Of Mbr Etc Please Eccuse My Lack Of Knowledge)
