    How to reformat my XP partition and reinstall XP??

    Hey guys, I need help, and maybe this can fix it. My XP always freezes when playing a game, usually after the first few seconds. My Vista doesn't have that problem. I want to go back to XP, but that freezing problem is not letting me go back. I have 2 partitions, one with Vista,and one with XP. How would I go about reformatting only my XP partition and stuff, without touching my Vista partition? Is there a good free program that can do it?

    Thanks.

    I think the bootloader is located in the vista partition, but I am not sure.

    Going to check it out, wait a moment.

    Alright here I am

    The full explanation is in the spoiler tags, do NOT try this unless you know what you are doing!!! so at your own risk.
    This is one way, there may be others, this is at your own risk, and can cause the loss of data.

    First you want to fully delete your xp partition:

    Finally happy with Vista, and want to remove the old XP from your system? A few changes to the boot loader have been made in vista, but the steps are very similar.

    not too difficult, simply load into Vista and format the partition XP is currently installed on. Since the Vista bootloader has control of the boot, there is no need to modify the boot.ini of XP.

    Restart your computer with either Vista CD 1 or your Vista DVD in the drive, if you don't you will be prompted to pick an operating system. Once into setup, choose repair console from the first screen (not install).

    Now the last option is for a DOS prompt, pick that.

    A DOS prompt appears, and type the following:
    bootrec.exe /fixmbr
    *this will essentially remove XP from the Vista bootloader

    bootrec.exe /fixboot
    *this will check that XP is no longer present in Vista's boot.ini

    Restart and XP is history.

    now you will need to reinstall XP.


    Tutorial Summary: We're going to use the DISKPART on the Vista DVD to shrink the Vista partition on the hard disk and create enough space for an installation of Vista. We'll then install XP, repair the Vista bootloader which will be overwritten during the XP installation, and then use the EasyBCD utility to configure Vista's bootloader to boot the XP partition.
    This is an updated tutorial, based on our first Windows Vista/XP dual-booting workshop. The main difference is that EasyBCD has been updated, but the processes are essentially unchanged.
    This tutorial was tested on a VMWare 6 Workstation and an AcerPower SK50 system.
    Prepare Windows Vista

    This tutorial assumes that Vista has been installed on a partition which takes up 100% of the hard drive, so we need to create some space. Boot off the Vista DVD. Hit Next from the start screen and then select “Install now”. (If Vista came preinstalled on your machine and you don't have a Vista install DVD, you can use the Gnome Partition Editor Gparted to do it. Our earlier tutorial on dual-booting XP and Vista if you've installed XP first describes how to use it.)

    Install Vista

    Don’t type in your product key and untick “Automatically activate Windows when I’m online”, then hit “Next”, and “No” when asked whether you want to enter the key.
    Vista Product Key

    When prompted to choose the edition of Vista you’re installing you can actually select any of them as we’re not doing a Vista install at this point. Also tick “I have selected the edition of Windows that I purchased” and hit “Next”.
    Vista Version

    Accept the license terms and hit “Next” again, then choose a Custom installation.
    On the screen where you’re asked where you want to install Windows, you should see a single large partition marked Primary – this is where Vista is already installed.
    Vista Partition

    Press SHIFT + F10. This is a Windows PE 2.0 shortcut to open up a command window – very useful trick.
    Command Tool

    Type in DISKPART and press Enter. This opens the Microsoft DiskPart application. You need to select the active disk, so type in:
    list disk
    The primary disk is generally Disk 0, so type in:
    select disk 0
    DISKPART Disk

    Now we need a list of volumes on this disk, so type in:
    list volume
    In this case Volume 0 is the one we want, so type in:
    select volume 0
    DISKPART Volume

    Now type in:
    shrink
    DISKPART Shrink

    DiskPart will go off and reclaim as much of the drive as it can – you should get at least 50% of the space back.
    Now type
    EXIT
    and
    EXIT (again)
    to quit the command window and get back to the install screen. Click Refresh and the partition window will update – you should now see the original Primary partition plus a brand new partition.
    New Partitions
    This is where we will install Windows XP. Eject the DVD, restart the machine (just hit the reset button) and boot off the Windows XP CD.
    Now, install Windows XP

    When the Windows XP setup reaches the point where you’re prompted where it is to be installed, you’ll see that while XP can see the space we created earlier, it can also see the partition with Vista on it.
    XP Partition

    You should be able to see the space you reclaimed on the disk earlier which has become "unallocated space".
    Create a second partition using the Windows XP installer screen above by selecting the free space on the drive and pressing "C" to create a partition (if prompted, choose NTFS as the file system.)
    Irritatingly, XP assigns a drive letter to this partition (C which means that it will use the next available drive letter after all the other physical drives have been taken into account.
    This means that the system drive of the XP installation won’t be C:.
    From XP’s perspective this isn’t really a problem – it’s smart enough to figure out where everything should go – but some applications make assumptions about where they should install to, and can’t cope with a non-standard Windows configuration.
    This was also the case with our tutorial on dualbooting Ubuntu and XP, where Ubuntu had been installed first. However in that scenario, even though the XP system drive had a non-standard drive letter, it couldn’t read the Linux partitions so there was no danger of the two systems overlapping. This is not the case with Vista/XP.
    Nonetheless, install XP as normal – there’s no need to do anything differently.
    IMPORTANT NOTEafter the initial file copy, Windows XP reboots and loads up the GUI-based component of the install. You may get the following error: “A disk read error occurred – press Ctrl-Alt-Del to continue”. This is caused by a corrupt bootloader – click here to see how to fix this problem.
    When the system reboots it won’t bring up a boot menu. Although XP recognises the Vista partition it doesn’t recognise Vista itself.
    The Windows XP bootloader gets installed to the MBR and Vista can no longer boot.
    When XP loads, open up Windows Explorer and you’ll see something interesting – a C: and (in this case) an E: drive.
    The C: drive contains Windows Vista, and as Windows XP can read NTFS partitions, it can browse and modify Vista’s file structure.
    More importantly, applications which have installation paths hard-coded into their install scripts rather than using Windows system parameter variables could easily dump files into C: when they should be installing to E:. This isn’t such a great situation.
    Two Drives
    Restoring Vista and dual booting

    Because you can’t use the Windows XP bootloader to boot Vista, we have to reinstate Vista’s bootloader to the MBR and configure it to manage both operating systems.
    Compared with scenarios involving Ubuntu where you have to reinstall the GRUB bootloader, getting Vista up and operational again is very easy.
    Boot from the Vista DVD and on the screen where you’re prompted to “Install now”, select “Repair your computer”.
    Repair Vista

    The next screen searches for local Vista installations – there should only be one, so click Next.
    Choose Vista

    This loads the System Recovery Options screen. Select the first option – Startup Repair. This looks for problems which would prevent Vista from loading (like a missing bootloader) and automatically fixes them.
    Startup Repair

    If you click on “Click here for diagnostic and repair details” and scroll to the bottom of the list, it shows that the problem detected and repaired was a corrupt boot sector (according to Vista, anyway).
    Repair Diagnostics

    Click Close and then Finish, and the system will restart and boot into Vista.
    Now we need to enable dualbooting with XP, and EasyBCD is the best application to achieve this.
    Download and install EasyBCD.
    Launch the app and go to Add/Remove Entries.
    Under “Add an Entry” and under the Windows tab and select in the Version drop-down list “Windows NT/2k/XP/2k3”.
    Change the Drive to E:\ and the name to “Windows XP”, then click “Add Entry” and “Save”.
    Vista & XP - EasyBCD

    Reboot the system and you’ll have two entries in the Vista bootloader, and can boot into either operating system.
    Vista Bootloader
    Removing Windows XP

    If you eventually decide that dualbooting XP as the second OS isn’t all it’s cracked up to be, it’s pretty easy to undo the changes made.
    Use EasyBCD to remove the Windows XP boot entry, and then go into Computer Management (right-click on Computer, Manage) and go to Disk Management.
    Right-click E: drive (the Windows XP partition) and select Delete Volume.
    Right-click the newly-created partition and select Delete Partition.
    Then right-click the C: drive (the Vista system partition) and click Extend Volume – this opens up the Extend Volume Wizard.

    Extend Volume Wizard
    The wizard gives you a readout on how much space is actually available to extend the partition – enter in how much you want to use and press Next. Vista will extend the system partition to reclaim the disk and Windows is well and truly gone.
    Fixing the corrupt bootloader

    If the Windows XP bootload corrupts during the install, performing a reinstall won’t fix it, nor will going into the XP Recovery Mode and attempting to repair the MBR.
    Luckily, the install was up to the stage where all you need to do is be able to boot from the Windows XP partition, and the install will pick up from where it left off.
    To achieve this, follow the procedure outlined above to restore the Vista bootloader (under "Restoring Vista and Dualbooting").
    This allows the system to boot into Vista, and then you can use EasyBCD to create an XP boot entry and boot into that to continue on with XP's installation. (For details on using EasyBCD, also see the section "Restoring Vista and Dualbooting".)
