Password reset on dell 518


Reset Your Windows Password Using the Command Prompt

1. Boot your computer using your Windows installation disc.
2. Wait for the setup files to load, and select your language. Click Next.
3. Click the Repair your computer link on the Install Windows screen.
4. Select the operating system to repair, and note the drive letter on which the OS is installed (it is probably C: or D:). Click Next.
5. Click Command Prompt at the bottom of the list of recovery tools.
Now you need to overwrite the Sticky Keys executable with the Command Prompt executable. Sticky Keys is an accessibility feature that allows a user to tap the Shift, Ctrl, Alt, or Windows key once to achieve the same effect as holding the key down. Ordinarily, tapping Shift five times activates Sticky Keys--but with this trick, you are going to make tapping Shift five times activate the Windows Command Prompt instead.
The instructions below use drive letter C: as an example. If your operating system is installed on another drive, replace C: with the appropriate drive letter.
1. In the Command Prompt window, type copy c:\windows\system32\sethc.exe c:\ and press Enter.
2. Type copy /y c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe and press Enter.
3. Exit the Command Prompt and reboot the computer. At the login screen, tap Shift five times. The Command Prompt will pop up.
4. Type net user username password, replacing username with your username and password with a new password.
5. Exit the Command Prompt, and log in using your new password.
To prevent another user from exploiting the same trick to reset your password, you can restore Sticky Keys as follows:
1. Step through the instructions above to boot the PC using your Windows installation disc, open the recovery tools, and launch the Command Prompt.
2. Type copy /y c:\sethc.exe c:\windows\system32\sethc.exe and press Enter.
3. Exit the Command Prompt and reboot the computer. Pressing Shift five times will now activate Sticky Keys instead of the Command Prompt. Store your Windows installation disc in a secure location.

How to boot from usb flash drive


There are many good reasons for booting your computer from a USB drive. For instance, if you want to try out another operating system without disturbing the main hard drive on your computer, then installing the new OS on an external drive is a great way to run the system through its paces and decide whether you like it.

This approach will offer you the flexibility of being able to run both operating systems on your computer. However, before you can boot the new operating system from the USB drive, you will need to change the boot order for your computer in the system BIOS.

Connect the external USB drive or pen drive to the computer before you power it on. Press the "Delete" key as the computer performs the "Power On Self Test" (POST) to enter the BIOS area of the computer firmware. The POST performs a diagnostic of components on the motherboard and does a cursory check of the hard drive, memory and processor. The POST only lasts a few seconds; therefore, press the "Delete" key quickly. Enter the administrative BIOS password if prompted to do so. Once you enter the correct password, you will see the main BIOS screen. Use the right-arrow key to navigate to the "BOOT" menu option at the top of the screen, and press the "Enter" key. Press the down-arrow key until the cursor is on the "Boot Device Priority" label. Hit "Enter," and press the down-arrow key again to highlight the "1st Boot Device" option. Press the "+" or "-" keys to scroll through the available boot options until the "USB Drive" or "USB-HDD0" label is the highlighted option. Press the "F10" key to save changes and exit the BIOS setup program. When the computer restarts, wait for the "press any key to boot from external drive" prompt to display, and then press any key on the keyboard to boot from the USB drive. Award or Phoenix BIOS Connect the USB drive to the computer. Wait for the POST to display on the screen, and press the "Delete" key to enter the BIOS. Enter the BIOS password if prompted to do so. Tap the right-arrow key until the cursor is over the "BOOT" menu option. Press the "Enter" key. Press the down-arrow key until the highlighted cursor is on the "Removable Devices" option. Press the "+" key until the "Removable Devices" label is on the top of the boot device list. Press the "F10" key to save the changes for the boot order in the BIOS and to exit the utility. After the computer restarts, press any key on the keyboard to boot from the USB drive when prompted to do so.

Bootable USB guide, here we assume that you are using either Vista or Windows 7 to create a bootable USB.
1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable.

2. Open elevated Command Prompt. To do this, type in CMD in Start menu search field and hit Ctrl + Shift + Enter. Alternatively, navigate to Start > All programs >Accessories > right click on Command Prompt and select run as administrator.

3. When the Command Prompt opens, enter the following command:
DISKPART and hit enter.
LIST DISK and hit enter.
Once you enter the LIST DISK command, it will show the disk number of your USB drive. In the below image my USB drive disk no is Disk 1.

4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do.
SELECT DISK 1 (Replace DISK 1 with your disk number)
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
(Format process may take few seconds)
ASSIGN
EXIT
Don't close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use "D" as my optical (DVD) drive letter and "H" as my USB drive letter.

6. Go back to command prompt and execute the following commands:
D:CD BOOT and hit enter. Where "D" is your DVD drive letter.
CD BOOT and hit enter to see the below message.
BOOTSECT.EXE/NT60 H:
(Where "H" is your USB drive letter)

7. Copy Windows DVD contents to USB.
You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).
Note that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.

Emachines T4010 won't start up, says image checksum, and that an image is corrupted


Receiving a bad image checksum error message when upgrading a computer to Windows XP means that a Windows system file such as user32.dll is damaged. This error occurs when any damaged system file is encountered that isn't overwritten during Setup. The repair process for this error involves voiding the damaged dynamic link library file from the DOS command line prompt and replacing it with a new copy from the Windows XP disk.

Insert a clean Microsoft Windows Millennium Edition (ME) or Microsoft Windows 98 Edition startup disk into the computer, and hold the reset button on the front of the computer until the system commences rebooting. Navigate the Windows startup menu with the keyboard's directional keys and select 'Start Computer with CD-ROM Support'. Hit "Enter" to continue. Write down your CD-ROM's drive letter on a piece of paper. At the command prompt, type "Drive:" without quotes (Drive should be replaced with the drive letter on which Windows is installed), and press "Enter." Type "cd windows\system32" without quotes, and press "Enter." Type "ren user32.dll user32.old" without quotes and again press "Enter." This renames your damaged user32.dll file so it is not recognized by the system, but still physically exists as a backup if needed in the future. Eject the Windows ME or 98 disk, and insert the Windows XP disk. At the command prompt, type "extract CDROMDrive:\i386\user32.dl_ Drive:\windows\system32\user32.dll" without quotes, replacing CDROMDrive with the CD-ROM's drive letter that you made a note of earlier, and replacing Drive with the system's drive letter on which Windows is installed. Hit "Enter" to execute the command. This process extracts a new copy of the user32.dll file to your hard disk, from the Windows XP CD. The new file will be found in the Windows/System32 directory. Restart the system by holding the reset button on the front of the tower until reboot commences.
