bios update windows 7

Your computer's BIOS (Basic Input/Output System) is the first software your PC loads. It sets the stage for your operating system, so to speak, by finding all your PC's various hardware components and letting the operating system know it can use them.

As with any software, your computer or motherboard manufacturer periodically updates the BIOS to fix bugs, add compatibility with new devices, improve caching functions, and make several other hardware tweaks that can speed up your boot time and fix annoying issues. These updates are available at the manufacturer's site. But if you make a mistake in the update process, you risk rendering your PC unbootable. Here's how to make sure your BIOS update goes without a hitch.

Step 1: Identify your current BIOS version.

Check your BIOS version, without restarting your PC, by using msinfo32.exe (as described in the text).

The easiest way to find your BIOS version is to open up the System Information app in Windows--just type msinfo32 into the search bar (for Windows 7/Vista) or the Run box (XP), and click System Summary; your BIOS version should now show up on the right under your processor speed. Record your version number (and the date that appears afterwards, if applicable).

Step 2: Check your PC/motherboard manufacturer's Website for BIOS updates.

Most PC manufacturers handle BIOS updates based on your specific line and model, so head over to your manufacturer's support page and check its listings for your PC, because if you download and install a BIOS intended for a different model, your PC probably won't work (although most BIOS updaters are smart enough to notice if you try to install them on the wrong hardware). If there is a BIOS update file available, grab it--along with any documentation it comes with, because often warnings and specific instructions are contained in the Read Me docs.

Those of you who assembled your PC yourself will need to look for BIOS updates from your motherboard manufacturer's Website. If you don't remember your motherboard's model number, you can look it up without opening up the case by downloading and running CPU-Z and clicking on the Mainboard tab.

Step 3: Read the included documentation.

Your PC's BIOS handles a lot of the nuts and bolts.

The BIOS updater's Read Me file will most likely include a list of fixes and new functions, often to support new hardware. Updating the BIOS for my Lenovo Thinkpad T500, for example, added support for a new AC adapter and a 1600-by-900-pixel screen resolution on an external monitor; the update also fixed fan speed and Webcam issues that could not have been handled by updating Windows or my specific device driver software.

More important, however, were these notes in the Read Me file: If I was running Vista on my T500, I'd need to make sure that I had a certain patch installed; and if my T500 had a certain graphics card, I would need to update its drivers above a certain version before updating my BIOS. Read and reread your docs, or you might make your PC unable to boot without even knowing why.

Step 4: Update your BIOS.

Most newer PCs have a fairly easy BIOS update procedure: Just download the .exe file from your PC manufacturer's Website, quit all open programs, run the .exe, and let it handle the patch; then reboot. If your PC suddenly shuts down in the middle of the BIOS update, you won't be able to boot up, so make sure you're not running off a laptop battery. Ideally, you're plugged into an uninterruptible power supply (UPS), especially if you're in an area prone to blackouts.

Older PCs, however, might require you to set up your own bootable disk to update the BIOS yourself. You might still be able to download an app that configures a USB thumb drive, blank CD/DVD, or even a floppy disk so that you can boot off of it to update the BIOS, or an ISO image file that can be used in your disc-burning app of choice (if you don't have such an app, try ISO Recorder for Windows XP or the version for Windows 7/Vista) to create a BIOS update CD.

Other systems will have you copy a few files to your bootable disk, restart, and open up the BIOS during startup (typically by pressing a specified key for setup options), and change the boot order so your system looks for a bootable USB drive or CD before loading the OS from your hard drive.

NTLDR is missing-Windows 7 Fix

“NTLDR is missing” is a notorious error message that usually bugs the Windows XP users, but it can also occur in Windows 7 even though it is an old Windows 2000/XP loader.  Windows 7 utilizes BOOTMGR instead of NTLDR, but there are  variety of reasons where users get “NTLDR is missing” error message in Windows 7.  It happens if you have an improper dual boot setup or due to improper Windows XP to Windows 7 upgrade, among several other reasons.  If you are having same issue with Windows XP, then try this tutorial: NTLDR Windows XP Fix.  This tutorial will highlight some effective ways to fix NTLDR is missing issue:

How to fix “NTLDR is missing” in windows 7:

Method#1: System Repair

• Insert the Windows 7 setup or System Repair CD into the CD/DVD drive and then restart your PC.

• Now boot into your Windows 7 setup CD/DVD.  If you have a Dell PC, then press F12, or F9 for HP, to access the boot menu.  It usually tells you what you need to press to access the boot menu during boot up.  If you are not sure, check your vendor’s documentation.  Select boot into CD/DVD.

• Now press any key to boot from Windows 7 CD when prompted.

NOTE: Make sure you press ANY key sooner as it only will boot into hard drive if you didn’t press any key with around 10 seconds.

•  Windows 7 installer will then pop up asking for language, format and input method.  Make appropriate selections and then click on Next to continue.

• Now click on Repair your computer.

•  It will then detect and list all installed operating systems.  Choose appropriate OS from the list and click on Next.

NOTE: If you notice the list is blank then don’t panic; it is normal.  Click on Next either way.

• From the System Recovery Options, choose Startup Repair. Let it do its thing and acknowledge any notifications it might display.

After repair, it will restart your computer and should fix the issue.  If you still see the “NTLDR is missing” message, then try method #2.
Method#2: Bootrec and Check Disk (chkdsk)
Follow steps 1-5 from the method #1.
6.  This time instead of startup repair choose Command Prompt.
7.  Now at the command prompt, type in the following commands, and press Enter.
bootrec /FixMbr
Bootrec /FixBoot
Bootrec /RebuildBcd
chkdsk drive: /f
chkdsk drive: /r
Note: Replace drive with the proper drive letter where your Windows 7 operating system resides.
You can also try other useful chkdsk commands and Recovery Console commands.  You can also check addition info from Microsoft support forum.
If problem persists, let me know in the comment section below.

linux and windows 7 dual boot

Dual Boot Your Pre-Installed Windows 7 Computer with Ubuntu

You have a new computer that came with Windows 7 pre-installed on it, and you want to create a dual boot system so you can run Ubuntu Linux as well. Here we take you through the process to install Ubuntu on your pre-installed Windows 7 machine.
For this demonstration we’re using Windows 7 Home Premium (32-bit) and Ubuntu 9.10 (32-bit)
Install Ubuntu
Here we will set up a basic dual boot system with the Ubuntu 9.10 disc that will create GRUB as your boot loader. On the Window 7 machine pop in the Ubuntu disc and boot from it.

If you experience a problem with the graphics with Ubuntu not displaying correctly, go back to the start screen, hit F4 and select Safe graphics mode.

Continue through the installation steps by selecting your language, time zone, and keyboard layout. When you get to the following screen (step 4 of 6), the easiest method for beginners is to select the first option– Install them side by side, choosing between them each startup. On the first bar you’ll see is the entire Windows 7 partition. Then on the second bar, you can slide it up or down to specify the amount of hard drive space you want for Ubuntu.

The green area represents the amount of space we’re leaving for Windows 7, and the brown is the space we’re allocating for Ubuntu.In this example we’re sliding it down to 10GB and leaving the rest for Windows.

Click continue to the verification dialog box.

In the next step create your user name, password, and configure log in options.

If everything looks good, go ahead and click Install. If you need to make any changes you can still go back and make them at this point.
 
The installation will start showing a progress bar and display new features in Ubuntu 9.10.

The amount of time it takes to install will vary from system to system, and once it’s complete, go ahead and restart the machine.

When the machine reboots you’ll see the GRUB loader where you can boot to Ubuntu or Windows 7.

One thing to point out in my experience with this method is when you first boot into Windows 7, Check Disk runs, then reboots and you need to choose the Windows 7 option again from the bootloader.

Conclusion
This should help get you started in enjoying a Windows 7 / Ubuntu Linux dual boot configuration. There are definitely other ways to get a Windows / Linux dual boot system, but if you want a quick method, so you can try out Ubuntu, this method works well.
