Dual Boot with Xp

I have a dell vostro 200 with 3gb of ram and I want to dual boot with windows xp pro on the computer I added a second hard drive and installed xp and still have vista on the C: drive

Xp is on the D: drive

I have a copy of easyBCD on a thumb drive but I haven't used it in a long time.

Can some one walk me through the process of reloading the Master Boot Record

I know how to use the program but It's been so long I just forgot what tab to click to load up the new boot entry

If anyone can help me it will really be great.

I Have vista installed first just want to reload the boot loader with xp added to the menu.

It depends if now you are booting into XP or Vista.

If now your computer boots straight to Vista:
- Click Add/Remove entries, in Add Entry section from drop down menu select Windows NT/2K/XP, select D:. Click on Add Entry

if you are booting to XP:
- In EasyBCD click Manage Bootloader. Select Reinstall bootloader, then click Write MBR
- Click Add/Remove entries, in Add Entry section from drop down menu select Windows Vista/Longhorn, select C:. Click on Add Entry
