Lost boot menu

Need help.
I have installed Win 7 on my F:\ =slave HD
Unfortunately I have lost the boot menu at which I can boot my Win XP or my Win 7.

At the moment I can only use my Win XP.

Any help in this is appreciated.

You might need to reinsert the Windows 7 CD and do a "startup repair" from the options menu.

If that doesn't work, try using BCDEDIT to edit your boot config. There's a good article on that here:

Thanks Ian for your support.
But non of the suggested works for me. Probably bec. I do not understand.

I cannot find any obtion to repair start when inserting the Win 7 DVD.
It just wants to install again!!!

Have read the article suggested. But that one I understand can only be used if one can boot into Win 7 which I cannot.
I can only boot into Win XP

I am sorry maybe I am not enough skilled for this.
