BIOS changed primary drive and I do not have password to change.

Recently I installed an external hard drive to my computer. After shutting down computer & re-starting, I get the DOS screen or I have to press F10 & the scrol to C Drive & press enter before my computer will start up. I bought this computer from a computer show & did not get any discs with it. The computer changed the primary drive to the external drive, but I want to put C drive as my primary. I need to know how I can do this.

Remove hdd password

You can change it but not 'remove' it. Simplest is to use '00000' as the default password.
1 Shut down your computer.
2 Press the power button on your computer. While it is booting, press F2 repeatedly (do not just hold it down) until you arrive at a system screen showing a series of
options. This screen is called the BIOS Setup.

Password Vault

3 Use the down arrow key on your keyboard to scroll down to "Security" in the left-hand column.
4 Arrow right to display a sub-menu under Security in the left-hand column.
5 Arrow down to "Internal HD PW" in the left-hand column. (That stands for Internal Hard Drive Password.)
6 Delete the old password (if any) and, in the same box, enter a new password of at least four characters in length in the main screen at right.
7 Write the password down and keep it in a safe place.
8 Hit Enter.
9 Hit the Escape button on your keyboard to exit the Internal HD PW menu, then hit Escape again to proceed to the Exit screen of the BIOS Setup.
10 Arrow right to save the changes you made to the password, then hit Enter on your keyboard to exit the BIOS Setup.
11 Restart your computer and use the password you created in the BIOS Setup to gain access to your hard drive.

Remove password from hardrive in bios

Before your computer loads your operating system, it starts by running the BIOS program, which is extremely important because of its various options.

You can even set a password on your hard drive so that nobody can use your laptop computer without your password.

Once you put in the password into your hard drive, you can only remove it by accessing the BIOS system and deleting the password completely from the memory of your computer.

Save all of your important files on an external hard drive or similar storage device.
This is a precaution to avoid losing all of your files when making changes to the BIOS.

Then, restart your computer.
Wait for your computer's operating system to ask you to access the BIOS menu.

This may be at different times, depending on the manufacturer of your computer.
It can ask you when the manufacturer's logo comes up, or on a separate screen indicating for you to click the "F2" button on your keyboard to start.

Access the BIOS menu by clicking the key or combination of keys that you are informed to click. This information can be found in your computer's manual, but it changes between different companies.

Commonly used keys for this process are "F10", "F2" and "Delete."
Go to the BIOS option that contains your hard disk drive password.

The option that will lead you to this password varies immensely due to different laptop models, but it may appear as something such as "Advanced" or "Security."

Look for the option for changing the password, which should say "User Password," and then click "Enter." Put in the existing password and then click "Enter."

Do not enter any password into the blank fields asking you to enter a new password, and this will remove the password.

Exit the menu by clicking "Save and Exit." Click "Enter."

Hard drive not being found

1 . Shut down the computer. Unplug all cables and peripheral devices.

2 . Remove the computer's side panel. (Cases vary. Some will require a small Phillips screwdriver for removal and others feature screw less designs. Please see your case manual if you are unsure.)

3 . Locate the newly installed hard drive. Check that two cables are running from the hard drive to the motherboard and to the power supply. If you see only one cable or if either of the cables are not securely seated, plug in the appropriate connector(s).

4 .
Leave the case's side panel off for now. Reconnect the power cable, monitor cable, and keyboard and mouse connections.

5 . Restart the computer. Enter your BIOS immediately. (Your BIOS usually alerts you to the key required to adjust settings. If your screen does not show this information or if you are unsure, consult your motherboard manual.)

6 . If it is an IDE hard drive, enter the IDE settings. The BIOS should show the hard drive. Configure it as primary or secondary, according to your computer's configuration. (If you have only one drive, set this to primary. Otherwise, set as secondary.)

7 . Save your settings, and exit the BIOS. Once you are certain that the the PC is recognizing the hard drive, replace the side panel.

Can I add an additional internal hard drive?


Yes, you can add additional hard drive.Please follow the below steps to add the drive sucessfully.


Make sure you have room for an extra hard drive, here's one way to do this:

1. Restart your computer and go into the BIOS menu as per below instruction.
Steps to enter BIOS:
After turning ON, immediately press the F10 key if your computer was built in 2006 or later (came with Vista). Press the F1 key if your computer was built before 2006 (XP or earlier). Press the key once every second until a BIOS Setup utility screen opens.
2. Go to the "Standard CMOS Settings."
3. In this menu, you will find four settings labeled as follows: PRIMARY MASTER:, AUTO/PRIMARY SLAVE:, SECONDARY MASTER:, SECONDARY SLAVE:. Change all fields to auto detection.
4. Reboot your computer.
5. On the first or second screen, you will see something like the screen above and it will say detecting (drive(prim/sec)) : (name of the drive if present). If any of them say none, remember which drive it is. If all of them have a drive name, all your bays are filled and you can't add a new hard drive without removing a disk drive or hard drive. Consider making an external USB drive.


1.Shut down your computer.
2.Unplug all of the cords from the back of your computer and pull the computer out from the desk.
3.Remove the case screws. If you're having difficulty, it's a good idea to consult your manual on how your particular case is removed. Put the screws in a safe place so you don't lose them. Remove the side panel and place it out of the way.
4.Find the area where all the flat ribbon cables (or SATA cables, which are smaller and usually red) connect to the main board. Find the cable that corresponds to the free drive either primary or secondary.


1.Set the jumpers so the drive knows whether to act as a master or slave. The jumpers are the set of pins on the back of the hard drive. They'll have a couple of rubber or plastic blocks covering some pins. Find the diagram or instructions for your new drive on to set the jumper for the master/slave.
2.Find the empty bay in your computer case. Using the screws that came with the drive or computer case, mount the drive.
3.Connect the cable to the hard drive. If it won't go in, make sure that the safety bump is aligned with the hole.
4.Connect a Molex power cable, (a smaller connector with red, yellow, and black wires.)
5.Put the side panel back on the computer and put the screws back in.
6.Plug all of the cables back into the rear of the computer, and connect them to their power sources if you unplugged them.
7.Boot up the computer. Go into your BIOS at startup.Check the BIOS auto detect to ensure the second drive is detected. On the screen that shows that primary master/slave,secondary master/slave you should see the name of your new hard drive.

Thanks & Regards

Computer crashed. Computer specialist restored drive. now cannot boot windows. Used restore disk. Did not work. computer boots dos screen then shuts down. boots again then shuts down.

Sounds like a Windows issue. Depending on how valuable it is to you to get your data off the drive, I would suggest buying a new hard drive (they are fairly cheap these days), installing Windows on that. Word of advice: Remove your old drive when doing the Windows install, so as not to accidentally select the hard drive your data is on. Once you have Windows installed, shut down your computer, remove the power cord, and install your old drive on a separate IDE channel or SATA connection. If your PC still tries to boot to the old drive, change the boot order in your PC's BIOS.

USB ports all seem troublesome

You cannot use wireless keyboard or USB keyboard in setting up the computer BIOS, what you need is a PS2 keyboard, if your motherboard supported USB booting, in Boot section of your BIOS change the Boot Priority to USB Generic Device, after you change the boot priority change the First Boot to Removable Device or USB Generic Device.. and after that save your configuration and restart the computer.. you must put the USB stick first before you configure the BIOS..

I want to boot from cd to change windows from xp to 98

enter the bios set up on start up. Go to boot sequence, change 1st option to cdrom instead of main drive. Save and exit. Let it boot up, put 98 disk in cdrom. Shut down, reboot and win 98 installation will begin asking you to over write existing ops sys. Choose yes and the install should be a breeze after this. Once xp is installed, dont forget to return to the bios and change back your boot sequence to hard drive as primary /master.

Frezes at verifying DMI settings. Already changed MB and Power supply. Lan connection only flashes green once in a while should be constant. Tried on a working terminal and does the same.

from pc help;
You did not say what operating system you are running but I assume Windows 95 or 98. It is possible some Windows
system files are corrupted or perhaps the system doesn't like your ram (if you added or installed ram recently). There
is also a possibility that there is something wrong with your BIOS and you *may* have to update it, but I would avoid
doing that if at all possible.
A quick fix - if the problem is software related - is to:
1. boot to a Windows startup disk (one that matches your operating system). this step assumes that your PC is setup
to boot to the A: drive before the C: drive (via the BIOS SETUP program). If you don't have a Windows startup disk,
you will have to make one on another person's computer that has the same version of Windows. You make one via:
2. run "scandisk c:" to make sure that any file corruption is fixed before going to next step
3. do a "sys c:" from the "a:" prompt to transfer a good copy of Windows system files to c: drive
4. remove the boot floppy, reboot the system and see if all is well.
If that does not solve the problem you may have to reinstall Windows 95/98. Ouch!
I recently had someone bring me a computer that had this DMI error message problem and I tried the "sys c:" method
(with the startup disk) without success and had to entirely reinstall windows 95 (and almost all applications except for
some programs that did not need to be placed in any Program Files directory or other special location) to cure the
problem. However nasty a job that is, it did cure the problem.
