F8 button not working for XP when Duol booting with 7

if we duol boot 7 with xp , f8 option works fine for 7 , but it will not even give you the f8 option to xp advanced option,
i have tried 100s times not working, i know there are other options to get to xp safe mode for example, by Run msconfig etc , and another way is to hold power button when starting windows next time it will ask you for advaced boot options ,
but i just wanna know is it possible to bring this advaced option ,i mean press f8 button after selecting xp to go for advanced boot option when duel booting with 7 thanks in advance.

thank you for the reply
here it is:

Pressing F8 should take you to the boot menu, select your boot device, press enter and immediately F8 again, you should now be where you want tot be.

Thank you so much you are totally right
We should tap F8 immediately after pressing enter , Previously i was taping F8 before presing enter obviously that's why it wouldn't bring up the advanced options , i didn't see that side of the picture ,but thanks to you i do now.

I appreciate your help , thank you so much
