I got a trojan from a key generator that my sister installed on my computer and now I can't reformat it... I have the Windows XP Pro CD. I've tried booting from the cd but it won't let me and I've also tried running it from Windows and when I click on Install a message pops up saying the setup cannot continue because the version I have on my computer is newer than the one on the CD and that if I choose to delete the newer version everything will be lost, etc. There's a continue button that is "blocked", and the only enabled ones are Cancel and Details. Basically, it won't allow me to re-install Windows XP. Is there any other way to reformat? What keys do I press to make it boot from the CD? Please help me!! :)

Oh, and I've tried System Restore as well, and it removed all my previous restore points! :)

Can you go into the BIOS and set the boot order so the computer first boots off the cdrom drive then the hard drive? Usually the Escape key while the computer is booting up will get you into the BIOS. Using the arrow keys and the enter key will move you around the bios and open up new windows to make changes. Escape key gets you out of windows and F10 usually gets you to the save changes window to get out of the bios. Then rebooting with the XP cd in the drive will let you boot to the CD and wipe the drive and reinstall XP.

_________________________

First thing to do, after you've done all the preparatory backing up of data and

collecting together of the various bits ‘n' pieces you'll need set up your system

again afterwards, is to reboot your system, go into BIOS setup and ensure that your

system is set to Boot from CD-ROM as ‘1st Boot Device', and your primary Hard Drive

as ‘2nd Boot device'. Make the change(s), if necessary, and then pop your Windows XP

CD into the drive, save and exit from BIOS setup, and watch for the text message to

pop up asking for you to ‘Press a key to boot from CD-ROM”. Make sure you do so!

You will be asked if you wish to install Windows XP. Press <ENTER> to begin the

process. You will then be presented with an ‘End User License Agreement' . Read it if

you wish (you really should, you know, but very few people actually do) and you

should press <F8> to accept the terms and continue.

Because an existing Windows XP installation is detected, you will be presented with a

screen asking if you wish to repair it. Press <Esc> to bypass the process (do not

repair).

Wiping your Hard Drives clean


The next screen you are presented with is where most people have difficulty. You will

be presented with a screen offering some choices of action, and a list of existing

hard drive partitions which also indicate existing Windows installations. My

suggestion for the best course of action is this:

* Remove existing partitions
* Create new NTFS partitions
* Install Windows XP on the first partition of your Primary hard drive


Highlight the first partition, press <D> to indicate you wish to delete it, and

follow the prompts to remove the partition. Continue the process for other

partitions. When you've finished removing the partitions, and are left with a list

indicating the drives and the ‘Unpartitioned space' they contain, highlight your

primary drive and press <C> to indicate you wish to create a new partition. Type the

size (in Megabytes) you wish the partition to be, or press <ENTER> to create a

partition using all available space on the drive. Repeat the process until you've

created all the partitions you wish to have.

A more detailed description of the process can be found in the section “How to

partition and format your hard disk using Windows XP Setup” from the KnowledgeBase

article “ HOW TO: Partition and Format a Hard Disk in Windows XP”

Putting Windows XP on your System


When you've finished, highlight the partition you wish to install Windows XP to (the

first partition on your Primary Drive is the best) and press <ENTER>.

Follow onscreen prompts during the process of installation, and ensure you leave the

Windows XP CD in the drive whenever your system reboots during the process. If you

get another prompt to “Press any key to boot from CD” keep your hands in your

pockets! You don't want to go back and start over again!

Note : If you are using an XP Upgrade CD, you will be asked for a qualifying product

during installation. Pop the CD with your older version of Windows into the drive,

press <ENTER> or click ‘OK' as prompted, and return your Windows XP CD to the drive

when asked. You may be prompted to ‘Create a Startup disk' and you can safely

‘Cancel' from that step if you do not wish to create a Startup diskette.

Provide such local information as requested during installation, and also such

details of existing Local Networks that the system is connected to. Provide details

of User Accounts you wish to have on the system, and passwords if you choose to use

them. When the process has completed, you will be prompted to ‘Activate' Windows XP.

Opt out of Activation at this stage, because it's better to Activate after you got

your system fully set up, and have confirmed that all is working as it should. You

can also safely bypass the Product Registration, as it serves little practical

purpose.

When all is completed, you will need to enter your password, if you've set one, to

access the Windows XP Desktop.
