Windows 7: XP disappeared after 7 and ....

This is not a difficult thing to do, especially if you are familiar with using the command prompt.

Really ? It is a process thet generally never fails in this situation.
In first pic, click on the red bordered button : the 2nd pic will appear. click on the red bordered button, select win xp/nt/2k/2k3, and then in the third pic, click the red bordered button, thats all.

But my dear friend, whatever method of fixing the issue you may follow, restart/reboot is the must at the end to take the process effect. It is unavoidable.

Edit : you may try softpedia.com/EasyBCD insted of the beta if you want.

This is not a difficult thing to do, especially if you are familiar with using the command prompt. You will create the menu entry for XP manually. Hopefully, the necessary files are still there, if not, if it doesn't work the first time, we can find the correct files and move them to where the need to be.

From Windows 7 open an elevated command prompt: "Start", "All Programs", "Accessories", right click on command prompt and run as administrator.

Then type these four lines, one at a time, press enter in between.

Bcdedit /create {legacy} /d “WinXP”

Bcdedit /set {legacy} device boot

Bcdedit /set {legacy} path \ntldr

Bcdedit /displayorder {legacy} /addlast

At the reboot, you should have a menu entry for your XP. If not, we need to look at your system in more detail:

You would need to attach a picture of the Drive Management Utility drive map:

After rebooting and choosing WinXP :
" Windows could not start because the following file is missing or corrupted:
<Windows root>\system32\ntoskrnl.exe
Please re-install a copy of teh baove file. "

I didn't remove anything, i tried but i couldn't.

This is not difficult to fix. You have given good information above. There are three XP files that must be in the "Boot" partition so you can dual boot, as shown in the link provided above:

"Three files must be copied: boot.ini, NTDETECT.COM, and ntldr. Folder options must be set to "Show Hidden Files". I had to use "Properties" to give my user permission to access the files. Then it was a simple copy and paste. These steps are detailed here: Solve Dual Boot Problem with Windows 7."

Before proceeding, we must have a screen shot of your drive map. The links quoted above will show you how to do that. It should look something like this:

If you look carefully in the C folder, there is no boot.ini file!!

You can search for it.

You can create a new text file, copy this into the file:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

Save the file as: boot.ini

and try to boot to XP again ...

Oh, yes;
But this one only has one OS, if i enter this, wouldn't it show only XP at the beginning for choosing OS ?
