Due to a virus and boot up loop, I have completed a PC Recovery on a Compaq Presario with Windows XP SP 2. The hard drive now has a partition with C maintaining my old files and PR (D) the recovery partition which the system now boots into. I am able to copy or move files from the C partition onto the desktop D partition, but the D partition is very small (according to disk management). Should the system be booting into the D partition and if so, do I need to resize it and how? Also how do I get the programs residing in the C partition (such as McAfee) to run in the D partition?

virus is the cause. You are going to have to put in your windows cd and boot from it. Then do a "repair" and hopefully recovery your system if not you are going to have to do a total system wipe.

which operating system ??
Shut down your computer and restart it.
Watch for the Compaq logo, then press the "F1" key to enter setup.
Press the right arrow within setup to go to the Boot menu.
Press the down arrow to access the "Boot Device Priority" option.
Change the first boot device to CD-ROM by pressing the down arrow until "CD-ROM" is displayed.
Eject the CD tray and place the recovery CD that came with your computer into the tray.
If you do not have a recovery CD, you can order one directly from Hewlett Packard.
Shut down and restart the computer.
The Presario will automatically boot from the CD and begin the recovery process.
Select the operating system your computer shipped with.
Many Compaq recovery CDs support multiple operating systems, so be sure to choose the operating system your computer shipped with.
Insert the operating system CD when prompted.
Enter the license key for the operating system when prompted.
The license key is typically found on a small tag located on the top or side of the computer.

There are multiple instances when you would want to wipe your PC's memory clean and reset it to the factory defaults.
Called "formatting," it is often the last-ditch effort to restore a PC to functionality.
You will also have to format your PC if it gets crippled by viruses.
Although these instructions are for the Compaq Presario, the steps are essentially the same for all Windows-based PCs.
Be sure that you want to delete everything--this process is irreversible.

Back up any data that you want to keep by saving it to removable media, such as external hard drives, flash drives, DVD-R, etc.
Unplug all peripheral devices, except for the keyboard and mouse.
Turn on the computer.
As the computer is starting, repeatedly press F1 to initiate the recovery process.
When the BIOS setup screen appears, press the right arrow key to select "Boot". Press the down arrow key to select "Boot Device Priority" and press "Enter".
Press the down arrow key to select "CD-ROM" and press "+" to move it to the top of the list.
Open the CD-ROM tray, and insert the system recovery disk.
Exit the BIOS setup by pressing "F10". Be sure to select "Save Changes and Exit".
System recovery should initiate.
If it does not, and the PC loads Windows, then you have either failed to set the CD-ROM at the top of the boot priority list or you exited the BIOS setup without saving.
Press "R" to begin the recovery process.
When prompted, select "Full System Recovery".
Restart the computer when the process has completed.

Hope this helps.

Your computer is infected with viruses. Solution: install and update anti-virus. You can use anti-virus free (Avira or AVG). Perform a virus scan process, with the option, if a virus is detected, the primary action "Repair" and secondary action "Quarantine".

hopefully help

if you still have an installation disk, put it in, restart, and run a startup repair. if that doesn't work, try to do a system restore. if that doesn't do anything you'll have to completely re-install windows.

Sounds like a virus. That kind of virus is almost impossible to remove. It is easier to reformat and fresh install Windows.

You could have a Boot Sector Virus. you would need to run anti-virus software to try and remove this issue. I would recommend Avast or AVG. I have attached a link of website that microsoft recommends. http://support.microsoft.com/kb/49500/EN-US/
