Can't boot into 7 after xp installed (dual boot)

http://answers.microsoft.com/en-us/windows/forum/window...

It's amazing what you can learn if you search the net first.

If you want to realize dual boot Windows 7 and XP under XP, you just need first install Xp and then shrink your hard drive to recreate a primary partition, and then install your Windows 7 on it. That’s OK. But if you want to realize dual boot under Windows 7, it’s a little hard.

First you need to prepare Windows 7 installation disc and Windows XP installation disc.

Step1. Under the Windows 7 OS, shrink your hard drive and create a primary partition for XP.

Step2. Start your computer from the Windows XP installation disc and install XP on the new-created partition. (Do not install at the wrong place or you may cover the WIN7 OS)

Step3. When the installation complete, now you will find you could only boot from Windows XP, the option Windows 7 is not at the boot menu.

Step4. Start your computer from Win 7 installation disc, select “Repair your Computer” at the main interface.

Step5. In next page, select “Command Prompt”.

In the pop-up window type the command below: one by one
bcdedit /create {ntldr} -d "Windows XP"
　　bcdedit /set {ntldr} device partition=D:
　　bcdedit /set {ntldr} path \ntldr
　　bcdedit /displayorder {ntldr} /addlast

After all of the command above works completely, now you could restart your computer and you may find a new entry for Windows 7 on your boot screen.

When dual booting microsoft OS's, you need to install from the oldest OS to newest. In this case, XP needed installed before windows 7. You can however rerun the windows 7 install and do a repair install and it should fix the bootloader.

You can no longer run a repair install of win7 from outside windows. You need to run the repair install from inside the build, which he can't do because it wont' boot. Read the KB article I posted, all the info is there.

thanks for the replies

I should have also noted I do not have a windows 7 disc. I looked into Paragon Rescue Kit Free but have had no success. If it comes down to it if I delete the windows xp partition will 7 work?

"I looked into Paragon Rescue Kit Free but have had no success. "

The lack of details/information is astounding. How do you install win7 without a disk? You do know that if you downloaded it you can burn it to a disk right? No success? Care to share the error msg? READ WHAT I POSTED! The KB article will fix the issue. I've used it twice now with no problems.

thanks got it 4745454b. i was selecting windows 7 in easy bcd which was not helping. this is a business laptop and was given to me with 7 installed i was not given a disc nor do they know what happened to the install disc. ill take a damaged self esteem for a fixed computer any day =).
