Dual Booting XP with 7 - Now need to reinstall xp

[cube3d]

Hi All,
I have a pc that is dual booting with winXP (32) and win7 (64) both on seperate HD. Win XP was installed first followed by Win 7 using a guide from this site. On start up I get the option to boot 7 or my older system.... all has been fine but I know need to reinstall my winXP system.
I am a bit concerned if I reformat and install the XP drive this might mess up the dual booting into 7?? Can any one let me know if this is the case and whether i can, and how i reset this up?

Any advice greatly appreciated

You will need to install EasyBCD to XP, then just add Windows 7 to the boot entry. You may have to run your W7 install dvd to run a startup repair ( up to 3 X ) but it usually fixes it on the 1st go.

Make a Windows 7 system repair disc 1st, if you do not have a W7 install disc.

Thank you. Ill give that a go..
Can I just clarify... do you mean install easyBCD to the new XP install?

Guess i better back up on the basis of having to reinstall both just incase.

Here you go.. as mentioned Xp and 7 are on separate physical drives.

bootmgr and bootmenu is on winxp partition! If you format it... it's gone.
Simply reinstall winxp
Then perform a startup repair from win7 installation CD or win7 rescue CD.
Then add winxp to the win7 bootmenu using easybcd

On the left side of EasyBCD, click on the Add New Entry button. (See screenshot below)

A) In the top section under Operating Systems, click on the Windows tab. (See screenshot below)
​

B) To the right of Type, select Windows NT/2k/XP/2k3 from the drop down menu. (See screenshot below)

WARNING: Be sure to leave the Automatically detect correct drive box checked.

C) To the right of Name, you can leave the default Microsoft Windows XP as the name to be displayed in the Windows Boot Manager, or you can type whatever name you would like to have instead. (See screenshot below)
​

D) Click on the Add Entry button. (See screenshot below)

You must unplug the XP HD first, plug its data cable into WIn7 HD or reboot into BIOS setup to set WIn7 HD first to boot (after DVD drive),

then mark the Win7 partition Active before running Startup Repair - Run 3 Separate Times
or it will not write the System boot files to Win7 HD.
