dual boot (WIn XP & Win 7). Problem!!

Before installing Win 7, I have been using Windows XP. I wanted to make dual boot (Win 7 & Win XP). After installing Win 7 (on 2nd partition, not the same as Xp), it didn't recognize Win XP and now I only have Win 7. I cannot run Xp, but it is installed on my PC..
According to this situation, are there any ways to access my Xp, and if is possible to have two Operating System in good working?

If you go to the start menu search box type msconfig and hit enter.
in the window that pops up what does it have listed in the boot tab (please don't change anything yet, just want to know)

The instruction helped me to solve the problem with dual boot. Thanks

Now, when I start my Pc it shows me Win 7 & Xp, but i got another problem. When I chose Xp, it tells me that I need to install it again, because one file is missing. If I do that (install Xp), will I lost Win 7?

When I choose XP, I got this on my screen

Windows Boot Manager

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Win installation disc and restart your computer
2. Choose your language settings and click next
3. Check repair computer

If you do not have the disc contact your system admin for assistance.

File: \ntldr
status: 0xc000000f

Info: The selected entry could not be loaded because application is missing or corrupt.


That's what I got on the screen!

You get "ntldr missing or corrupt" or similar messages because the XP install puts ntldr and ntdetect.com on the first partition. The boot loader sends it to the XP partition and no boot files. Boot into a command prompt using the XP install CD and copy the files ntldr and ntdetect.com to the XP partition. It should boot from then on.

Just do a dir /s ntdetect.com in the booted command prompt to find the files on the XP disc to copy.

Could you give me more details how to do that, please. I am not a professional as you.

Please post back a screenshot of your full Disk Management drive map using Snipping Tool in Start Menu.

It's likely you only need to install EasyBCD 2.0 to Windows 7 to Add XP on the Add OS tab, as it will copy the needed files to Windows 7. But we need to see if there are any problems with the setup so far.
