When attempting to boot a black screen appears that reads "Loading PBR for descriptor 2...done." Below that: "A disk read error occurred/Press Ctrl+Alt+Del to restart" Re-starting, however, does nothing--the same message appears every time. The problem began when the computer's power source was accidentally cut so the device was improperly shut down.

Before you use the Recovery CD you need to backup your data because to restoring your laptop will wipe your data off the hard disk. To backup your data when you cannot boot up your laptop, remove the hard drive and connect it to an USB hard drive adapter. Connect this hard drive/USB adapter into the USB port of a working computer. The computer will see it as an external storage device, you can then open the folders and backup your data. You can then fit the hard drive back into the Dell laptop and boot up with the Dell recovery CD to reinstall Windows etc.
And again and again and drives you up the wall.OK-boot sector is corrupted, or hard drive is going south.What you can try is system restore.On boot see which button is designated for that-usually f10 or f12.Start tapping that button and follow instructions. If that failed, the only option is to reinstall OS.If you have a lot of stuff that you want to save, install Windows in different folder, say WindowsA.All your stuff will be saved on the Hard drive-My Documents.Good luck and keep us posted.
This is saying that the ntldr, which is a file necessary to start windows is missing. You will need to follow one of these steps in the links, below: Note, if you have Windows Vista or Windows 7, you'll need to boot from the Windows system disk and follow the prompts to repair Windows http://www.fixya.com/support/r4501608-when_windows_xp_start_primary_fix http://www.fixya.com/support/r4501848-when_windows_xp_start_secondary_fix
"Loading PBR for descriptor 2 ... failed" would be the exact error message if the MBR is unable to load the partition boot record for the second partition. There may be more, but here are three possible causes: 1) the partition table is corrupted so that the descriptor points to the wrong place (i.e., says the partition is one place when it's really somewhere else);
2) the partition table descriptor points to the right place, but the boot record there is corrupted or has been erased; 3) The hard disk is failing and having trouble reading the sector with the boot record.
To check (3), run hard disk diagnostic tests. Press F12 when the machine is starting and see if the bios boot menu offers you a hard disk diagnostic test that you can run. Or even better, if you know the brand of the hard disk, most manufacturers should have a free diagnostic utility you can download to test the hard disk.
If it's not (1) or (3), then use Ctrl+F11 to run the Dell restore utility to recreate the Windows partition.
That is the boot loader message to boot to the NTFS Primary boot partition (Primary Boot Record for Descriptor 1 is the Utility partition)
Normally, this message flashes and the system boots, since it is not there is a failure in the boot process.
#1 run diags on the Hard Drive (CTRL+ALT+D at boot) and see if it passes
If it does
#2 Boot to you XP CD, press R for recovery console, and run the COMMAND CHKDSK /R see if the system will boot
If no go, go back to recovery console, try the command BOOTCFG /Rebuild then see if the system will boot
If That fails, try reinstalling Windows
If Diags Fail or all the above fail, replace the hard drive
I suspect that the viruses had infected some of the files that windows needed to boot up. The moment you ran the Mcafee, the scanning might have deleted or quarantined those files. That is the reason you're having this Loading PBR message because it is now trying to boot from the network and not from the hard drive. You will need to repair windows using the CDs that came with the computer (the Operating system CD/DVD) and run CHKDSK /R at the screen where it says 'repair your computer using the command prompt". If this does not work, chances are, you may need to reinstall windows and everything and that all information in your hard drive will be wiped out.
AH yes, Kristen very familiar with your issue, it is trying to load the primary boot record from a device it dosen't see , ( re: a floppy thats not there) you need to check the BIOS and make sure the booting sequence is correct (re:disable floopy if one dose not exist, etc) please write back if you need help doing all of these things
Boot to the Diagnistics FN+POWER at boot, run hard drive diagnostics. The PBR Descriptor 2 message is part of the normal boot process (directing the boot loader to Primary Boot Recond 2, the C: Drive) but usually flashes on an off so fast most people never notice it. Since the boot process is not going past the re-direct it is indicative of a bad hdd (Since the re-image process crashed)
Most likely you are looking at a hard drive replacement.
Regardless you are going to need an XP CD (you'll have to reinstall windows or run recovery console at a minimum)
