How do i access the boot menu on a Vizio All in one PC Model CA24-A0. Im trying to do a clean install of windows 7.

Try pressing F2 on start up or check the splash screen with the Vizio logo for a hint on the BIOS access key. If you have Windows 10 and fast boot, you might need to use the restart options menu. (Fast boot often keeps the computer from registering the key press before Windows starts to load.) From inside Windows, press the Start button. Select the Power icon and then hold the Shift key while you left-click on Restart. You should get to a screen that includes choices for Refresh, Reset, or Advanced Options. Choose the Advanced Options and look for an option for UEFI Firmware in the menu. This menu can also be reached from Windows by the Start Menu by selecting Settings > Update & Security > Recovery. Scroll down to the Restart button. After the restart, choose the Troubleshoot option and then Advanced Options.

I've often found that even with Fast Boot off, I will miss the timing for the BIOS access key press. Thus I will repeatedly press the F2 key during POST and hope to get lucky.

I hope this helps.

How to create a bootable Windows USB drive. A common use of a bootable USB flash drive is to use it to boot into Windows. Booting from removable media such as a USB drive allows you to perform diagnostics on a computer that is having trouble booting from the hard drive. You can also use the flash drive to install Windows, instead of using the Windows installation CD.
This guide will outline making a bootable USB flash drive with Windows XP, Vista, or 7. Before we begin, it is important to note that the computer you want to use your bootable USB drive must be able to use a USB drive as a boot device. Most computers built since Windows Vista was released are capable of booting to a USB device. Prior to the Windows Vista time frame, it is hit or miss with motherboards.

To determine if a computer is capable of booting to a USB device, access the computer's BIOS and check the bootable device list. If a USB device is listed, set the USB drive to be the first boot device. If you do not see a USB device in the list of bootable devices, your BIOS is not capable of booting to a USB device.
Note: You may need to have your USB flash drive plugged in when you access the BIOS).

Windows Vista and Windows 7 users To make a bootable USB drive for Windows Vista or Windows 7, you need to have Windows Vista or 7 installed on your computer. It is recommended that you have a flash drive of at least 4 GB in size, to store all the necessary files.
Tip: Before you start, plug in the USB drive and backup any files you have stored on the USB drive. The drive will be formatted during this process and all files on it will be deleted.
Note: You need to have a Windows Vista or Windows 7 DVD for these instructions to be successful.
1. Open an elevated Windows command line window by clicking Start, typing in cmd in the search text field, then pressing CTRL + Shift + Enter on your keyboard (at the same time). You can also access this by navigating to Start, All Programs, Accessories, right-click with your mouse on the Command Prompt menu item and select Run as Administrator.
2. At the command prompt, type cd c:\windows\system32 to change the directory to the Windows system32 directory. Ensure your USB drive is plugged in, type DISKPART, then press Enter. Type LIST DISK and press Enter.

• See our diskpart command page for additional information on this command.

3. You will see a listing of the disk drives connected to your computer. Find the disk number of your USB drive and type SELECT DISK [USB disk #], where "[USB disk #]" is the disk # for your USB drive. It should now state that your USB drive is the selected disk. If you're not sure what disk is the USB disk, eject the USB drive, perform step number 2 again, connect the USB drive again, and compare the results. Usually the USB drive will be the last drive.
4. Type in the following commands, one by one, pressing Enter after each command.
CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS
(may take a couple minutes, depending on the USB drive size)

ASSIGN

EXIT
Keep the command prompt window open, but you can minimize it for a little bit.
5. You will now need your Windows Vista or 7 Installation DVD. Put the DVD in your computer's DVD drive. Open up My Computer and note which drive letter is assigned to your DVD Drive and your USB flash drive.
6. Go back to the command prompt window and type in D: CD BOOT (substitute your DVD drive letter for "D:", if necessary) and press Enter. Type CD BOOT again and press Enter. Lastly, type BOOTSECT.EXE /NT60 H: (substitute your USB flash drive letter for "H:", if necessary) and press Enter.
7. The last step is to copy the entire contents of the Windows DVD to your USB flash drive. To do this, in the My Computer window (opened in step 5 above), right-click on the DVD drive and select Open to view the contents of the DVD. Copy all the files and folders on the DVD to the USB flash drive.
Your USB flash drive is now set up to be a bootable USB drive for Windows Vista or 7.

Usually a faulty main board. It will probably be very expensive to repair. Next time, do not buy an all in one PC. The quality is often poor and the repair cost is high.

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.

Clean Install Windows on a Sony Vaio

Even if a Windows operating system is already installed on your Sony Vaio, it is possible to clean install the same version again or clean install an upgraded version of the Windows operating system over the current operating system.
A clean install of a Windows operating system overwrites the Sony Vaio's current operating system and cleans the hard drive by automatically deleting all of the applications, files and settings that are stored on the Vaio.

Create recovery discs for your Sony Vaio using the Vaio's built-in VAIO Recovery Wizard.
Access Vaio Recovery Wizard by going to the "Start" menu and clicking "Help and Support." Follow the screens in the VAIO Recovery Wizard to make recovery CDs for your computer.
Transfer files and programs that you want to save onto an external storage device, such as an external hard drive or a CD.
To transfer the files and programs to an external hard drive, plug the external hard drive into a USB port on the computer and drag and drop files from the computer into the external drive window.
To transfer the files and programs to CD, open a CD-burning software and choose the "Data Disc" option, upload all of the files into the program and "Burn" or "Write" them to the disc.


Place the Windows installation CD or DVD into the disc drive of your Sony Vaio.
If the computer is already on, reboot the computer.
If not, turn the computer on to boot the installation disc.

Follow the onscreen prompts to go through the installation wizard for the Windows operating system.
Enter the product key from the Windows operating system packaging, accept the terms of the operating system license and, if prompted to choose a type of partition for the Sony Vaio, select "NTFS."
Click the "Install Now" button on the last page of the installation wizard.
The operating system installs to the Sony Vaio.

Wait for the installation of the operating system to complete, which can take up to two hours on some systems.
Once the installation is finished, reboot the Sony Vaio and the computer should boot up to the operating system screen.

Check for loose connections. Is this a new sub woofer? Or have you had it for a while?

Try bringing up the boot menu (it will say what key to press on the splash screen) and choosing the usb. if that does not work try moving ports.

HI
