Windows 7: Boot manager screen not showing on bootup

Hi all,
New here, and seems a very imformative forum.
I have two computers, one with Windows 7 64bit on one drive, and Windows seven 32bit on another drive. When I boot up, I get a boot manager screen, and can choose which OS to boot from. Perfect
On my second computer, I have a SATA drive with Windows 7 64bit loaded, and a second drive with Windows XP loaded. Both systems work fine. However, when I boot up, I do not get a boot manager screen, giving me the option of booting into Windows 7 or XP.
Obviously, going to BIOS and changing boot priority works fine, but this is a pain. As computer one shows an option screen, why does computer two not display the same.
I have been into the Control Panel route to boot manager, and it only lists Windows 7. No sign of XP. Is this an XP/7 clash. I seem to remember a while back, having two XP drives, I was given the option of which drive to boot from.
Sorry this is long winded, but it explains exactly what is happening

Boot Win 7 then download and install EasyBCD Community Edition 2.2.0.182 Free - Softpedia
Next boot you will get the boot selection menu.

Why do you go into BIOS to change the boot order. That's what the one-time BIOS Boot Menu shortcut key is for. Try that.

If you don't like that method then set Windows 7 first to boot in BIOS setup, boot into it to install EasyBCD as suggested, add XP on Add OS Entry tab.

Solved thanks....used the EasyBCD method......great stuff fellas
