Dual Boot, cannot see XP

I had installed Windows 7 RC and it was working fine dual booting with XP64. I just installed Windows 7 Pro 64 but on the same parition that RC was installed on. When I first booted up it did not ask me if I wanted to go to an "Earlier Version of Windows". So I tried going to startup and recovery to see if XP was showing up under the Default operating system pulldown and it wasn't. So I downloaded Easy BCD and added XP. When I did this it gave me an error about NTLDR not found. The entry in BCD lloks like this

Entry #2

Name: Windows XP64
BCD ID: {ofba9664-f712-11de-a494-d8761eo8b88f}
Drive:\Device\HarddiskVolume1
Bootloader Path: \NTLDR

Now when I boot it gives me the option of either operating system. When I choose XP64 it says I am missing \NTLDR and I need to use the XP64 disc to repair it. How do I get back to dual booting with XP64????

I just wanted to add more detail. Windows XP64 is installed on D: Windows 7 is installed on C:. I have done many searches on this and looked at several different methods to get XP64 to boot but to no avail. I have been using the bcdedit command and easy BCD (for Vista). I have copied NTLDR from my wondows XP64 dvd to D:\. Now when I choose Windows XP64 from the boot menu it says:
Invalid Boot.ini file
Booting from C:\windows\
NTDETECT failed

I have a lot of apps on win XP64 that I need for my business. Any help would be appreciated.

Hi hammerpe33. When you boot into Windows 7, can you see your XP partition in Computer? If so, what is the drive letter?

*Edit never mind, I was typing while you posted the last set of information*.

I just tried following the instructions from x(perts) 64. I booted using Windows Xp 64 Disc. Went into repair mode. Went to my windows installation on D:. Entered my administrator password. Ran Bootfix. It wrote a new bootsector on Partition C:. I ran bootcfg /rebuild. I got:

Error: Failed to successfully scan disks for windows installations. This error may be caused by a corrupt file system, which would prevent Bootcfg from sucessfully scanning. Use chkdsk to detect any disk errors.

chkdsk does not return anything unusual. Now it will not boot at all. It just says NTDLR is missing. I don't care if I have to re-install windows 7. I really need to get WinXP back.

Try booting from the Win7 dvd and open a command prompt (print this page for more help) and restoring Win7's MBR. See here

Quote:
Use Bootsect.exe to restore the Windows Vista MBR and the boot code that transfers control to the Windows Boot Manager program. To do this, type the following command at a command prompt: Drive:\boot\Bootsect.exe /NT60 All
The link also outlines how to restore your XP dual boot.

Thanks you for your prompt answer. I followed the instructions. There were however some differences. Once in the command prompt fromt the Windows 7 DVD: Typing Drive:\boot\Bootsect.exe /NT60 All (I used the drive letter in place of Drive gave me an error. I had to change to the directory Drive:\windows\boot then run Bootsect.exe /NT60. That gave me an error telling me that the drive that windows 7 was on was access denied, but it did run the executable on it. After re-booting I did see the choice for Windows XP64 (thats what I named it). When I tried booting windows xp64 up it said:

Invalid Boot.ini file
Booting from C:\windows\
NTDETECT failed

Windows 7 does work again! Progress!

Oh one more thing the document says I need the following files:

  • Ntldr
  • Boot.ini
  • Bootfont.bin

    Note You need to use this file when you install the Windows versions of the East Asian languages.
  • NTDetect.com
I cannot find bootfont anywhere. Also these files are currently in d:\ but it seems they are supposed to be in d:\boot???

Bootfont.bin is not needed unless you have an Asian version of Windows. Ntldr, boot.ini and NTDetect.com should all be in your D:\ directory.

Sounds like you need to have another shot at running bootcfg /rebuild in the XP Recovery Console.

See here.

No luck. This is what I did. Booted up using the Windows XP dvd. Went into the repair console. Chose the D: drive (this is where XP 64 is) typed bootcfg /list. It says There are currently no boot entries available to display. Then I type bootcfg /rebuild and it says: Error: Failed to successfully scan disks for windows installations. This error may be caused by a corrupt file system, which would prevent Bootcfg from sucessfully scanning. Use chkdsk to detect any disk errors.

Not yet. I am going to ask for help from another Mod who has more experience with this type of issue than I do. In the meantime, back up as much data as you can to removable media.

Ok, I have sent Murf a message but it might be a few hours before he can reply (depends on timezones).
