Hard Disk Not Present
My daughter’s laptop, an HP Compaq 6510b, started to boot slower than usual, sometimes even fail to boot up. She has not updated her antivirus and she copied a file from a classmate which was infected with a virus. It would not boot up past the bootup options of Safe Mode, Safe Mode with Command Prompt, Boot Using the Last Configuration that Worked, etc. I do not know exactly what the problem was so I tried to reinstall the operating system to get to the repair option. I could not access the hard disk for some reason. It says the hard disk is not present.
Virus – the Culprit
I suspected there are boot viruses in the laptop that prevented me from accessing the hard drive. I searched the net for antivirus solutions and decided to download and burn a freeKaspersky Rescue CD from a selection of antivirus softwares.
I ran the 112 MB utility apprehensive of what will happen. I found out that the Kaspersky Rescue CD uses a Linux distribution kernel and it booted up just like when I installed Linux distributions, listing all those commands on-screen. After a few minutes, I arrived to the graphical user interface (GUI) which allowed me to scan the hard disk. The hard disk was present and it took about two hours of thorough disk scanning for malicious codes. The rescue CD detected five viruses, including a Trojan.bat.shutdown.bi, Autoit virus, and a worm. I was prompted to delete the virus once detected and I did.
Using Kaspersky X File Explorer (XFE)
I tried to boot again using the hard disk, confident that the virus causing the laptop to shutdown was removed. Still it would’nt boot. I replaced the Kaspersky rescue CD once again to try saving the precious files of my daughter before deciding to wipe all the possible viruses that may have been left out after scanning since the Kaspersky rescue CD could not be updated as I am offline.
The CD booted as usual but I could not see the USB flash drive after I inserted it when I got to the GUI. I thought I needed to reboot inserting the flash drive right away on the USB slot, so that the application will detect the flash drive’s presence. It did and I learned how to use the rescue CD to save the files from the laptop to the flash drive.
To access the disc, just close the scanning window interface and click the “K” symbol. Find the File Manager and look for the folder with the label “Disc”. Clicking it should reveal the hard drive and the flash drive. I had a C and D partition then, and E folder appeared, with the flash drive’s name on it. Files from the hard drive can be compiled easily by just copying the files (or folder) and pasting them on the USB flash drive. I was able to save the precious files of my daughter and saved the day.
Final Touches
One more thing, I realized I need to make some changes in the default configuration of the setup setting before installing a fresh copy of the operating system (OS). In HP 6510b, this requires hitting F10 at boot, then executing the following:
1. Go to System Configuration
2. Go to Device Configuration
3. Go to SATA Native Mode (default setting to set to enable)
4. Change setting to Disable then press F10 to save/accept changes.
5. Exit and save, then reboot.
I was now able to boot the computer and successfully installed the original Windows XP Home Edition operating system. It has some defective files, however, and the installation would not complete. Luckily, I made a backup copy and reinstalled the operating system. It worked.
