HANG AT "VERIFYING DMI POOL DATA"
One day you are booting your computer and it stops on a black screen with a single message on it:
"Verifying DMI Pool Data"
This can happen for one or more of several reasons: (1) the boot files on your hard drive are corrupted. (2) the settings for your hard disk drive in the CMOS are incorrect. (3) the order of the boot devices in the BIOS is incorrect. (4) the BIOS is corrupt or has some incorrect setting. (5) there are loose connections to your hard drive. (6) the disk drive has gone bad.
If the boot files on your hard drive are missing or corrupt, you need to boot to a bootable floppy diskette which was made from the same version of Windows as your computer's operating system. When you reach the "A:\" prompt, type the command "sys c:" and press the Enter key. This should give you a message "File system transferred." Now you can try to reboot to your hard drive, after removing the diskette.
If you still cannot boot, you can boot to the bootable floppy again, and at the "A:\" prompt try using the command "fdisk /mbr" to rebuild the hard disk's Master Boot Record.
The settings for your hard drive in the CMOS may be incorrect. Use the key sequence required for you to enter the BIOS (usually, you see a message on the screen as the computer is starting up that says something like "Press Del to enter System Setup", which in this example is telling you that the Delete key is used to enter the BIOS.) Verify that the settings for the hard disk are on Auto Detect, or have the proper values. You can also verify that the order of the boot devices has been set correctly in the BIOS. Usually, the primary boot device is the floppy drive, and the secondary is the hard drive, with the third device (if any) being specified as the CD-ROM drive.
If none of the above corrects the problem, you may need to choose the option to reset the CMOS settings to the factory or default settings.
Perhaps you recently moved the computer or had new hardware installed in it. This could have caused connections to become loose or even broken. Verify that the cables for your hard drive, floppy drive, and CD-ROM drive are all properly connected.
If none of the above measures corrects the problem, your hard disk may have gone bad.
