If you can perform the repair that I mentioned is your other post, then your data will not be lost. If you have to reformat and reload the system, or the drive has failed, then you will lose the data. The only way to retrieve it is to send it off to a retrieval company, and that;s expensive.

Boot screen computer


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.

Disk Access: Sense operation failed


Have tried to reboot it through its own internal memory w/out the discs? Restart your computer, get into your bios to go to factory restore and do it from there. You should be good to go from there w/out the discs. : )

I have a Sony Vaio VGN-N130G. It crashed and I am trying to get it to reboot from the recovery disc but after the first disc starts the Complete C drive thing it stops and says ERROR 400 and can't...


Make sure that the operating System on the recovery CDs is the same as the one on your computer.
If you are trying to recover from a CD with Vista and your computer operating system is Win-XP that will not work.

Other Thing may be you had a hidden partition and some how you over written it or it is damaged.
check the hard disk partition stat.

Try rebooting and hitting the F8 repeatedly as soon as the boot sequence starts. When it comes up to an options screen select repair. From there you can let windows try to repair or select to install to the factory settings.

Vaio error message


This generally indicates a hard drive failure, but occasionally it's just an operating system glitch. Start by doing a system repair with your recovery or operating system disc. If the repair doesn't take, then reformat the hard drive and install a fresh operating system. If you have any problems during or after the format or install, then the hard drive has failed and will need replaced.
