Boot from a Windows Vista Install or repair disk and run the repair. See if that helps.

When you restart the computer keep tapping F2 or F3 (not sure which one on a Vaio), this should give you access.

This needs to be done before the BIOS hands over to the OS, try it as soon as you see the Vaio screen.

Use the Esc key or look for Exit menu. Have you change the boot order to boot from cd first? If yes, make sure you save changes on exit. While you are there (BIOS setup), take a look at the Main menu and see if the hard disk drive is being detected by the system.

Linda, can you give us the Vaio model? Also, disconnect any external drives connected to the computer before powering ON.

yes vaio model number would be useful, can then get some screen shots for you and show you where to navigate to in the BIOS.

hi Linda , try this link to start, follow the instructions on the screen and u will get it to boot from cd first. it should be the same as your model and if somewhere on the bios screen it says save and exit do so if all is good follow the instructions from the previous posts.

Linda if u need a repair disk go here and download the one for your system and burn it to a cd. http://bootdisks.windowsreinstall.com/
go here and download imgburn to burn the file to cd. http://www.imgburn.com/index.php?act=download
when imgburn opens click on write image file to disk, it will take u to another window and click on the little yellow folder and it will open a new window and find where the repair iso you downloaded for your system click once on it and then click on the open button near the bottom right hand corner, then it will take you back to the main window of imgburn, make sure u have cd in your cd drive and then click on write to disk at the bottom of the window and just wait till it is done.
if u need to find out what your system is click on thw windows start button and find the control panel link and click on it then click system and then system again all your info should be right there, write it down look for 32 bit or 64 bit windows version, go and download it from the link posted above. again do u have a cd drive on your Vaio { broken computer }

You need to put first in the boot list the device you are wanting to boot from.

Linda have u tried to pressing the F8 key when your Vaio is booting up to get to advanced boot menu, if not try it and if it comes up select safe mode with the up and down keys and press enter, post back on your results.

I think I will start this again from the beginning, just to make sure, since I only see lots of short posts.

Let's start with the BIOS boot menu. According to the user manual you can download here, to access the BIOS:

- Turn on the computer.
- Press the F2 key when the VAIO logo appears.
The BIOS setup screen appears. If not, restart the computer and press the F2 key several times when the VAIO logo appears.
- Press the LEFT ARROW and RIGHT ARROW keys to select "Boot" to display the "Boot" tab.

I suspect you will see something like this (surprisingly, this is not in the manual):


(Image credit: here)

Make sure your options show like in the image above. To change an option, select it with the DOWN ARROW and UP ARROW keys. Press the SPACE BAR key to switch an option from DISABLED to ENABLED and vice-versa. I think you have to press ENTER to change the selections of the boot priorities. You could even move the internal hard disk drive to the second priority.

- Press the LEFT ARROW and RIGHT ARROW keys to select Exit, select Exit Setup, and then press the ENTER key.
- At the confirmation prompt, press the ENTER key.

Your PC should now be configured to boot from the optical drive. Let's go to the next step which is getting a DVD to boot from. I don't know which CD or DVD you are using now. But your best bet is to get an official Windows 7 install DVD ISO image from here. They are useful to repair both Windows Vista and Windows 7 systems. Get the ISO image for Windows 7 Home Premium 32-bit English version (assuming you have a 32-bit system, which was typical while Vista was out).

Once you have downloaded the ISO image you need to burn it to a DVD. You can use both ImgBurn (instructions here) or the Windows 7 USB/DVD Download Tool (instructions here).

Once you have done this, insert the DVD you created in your VAIO first, and then restart your computer. It should display the message "Press any key to boot from CD or DVD...". At this point press any key just once. The "Windows is loading files" message should appear with a white progress bar, then the "Starting Windows" and the Windows logo should appear.

Next you will see this screen, select your keyboard layout and click "Next":

Click on "Repair your computer":

Let the window check for installed operating systems, select your Windows Vista installation and click "Next":

If at this point you see an error message it is because your system is 64-bit and the disk you downloaded is a 32-bit one or vice-versa. Download the right disk and repeat this process. If no operating system appears, then you might have more problems.

Next, click on "Startup Repair":

Let the system check for problems and repair them. Restart and do not press a key when asked to boot again from the CD or DVD, to check if the system works now. If after restarting your PC it still won't boot, repeat this process two or three times more. If it still won't boot, try this manual repair: instead of "Startup Repair" select "Command Prompt".

Here you will find a tutorial to backup your files using this DVD you have now. Follow the tutorial to check the letters of your drives (C:\, D:\ etc.) from Notepad's "Open File" dialog. They may be different in an environment like this: for instance your recovery partition may be labeled "C:", and your Windows Vista may be labeled "D:", although this is rather unusual.

Then mark your Windows Vista partition as active. Use the following commands from the command prompt:

diskpart
(you are now inside DISKPART>)
list disk
select disk 0 (select the hard drive with Windows Vista)
list partition
select partition 1 (select the partition with your Windows Vista installation)
active
exit

You can now try to restart. If it is not fixed, try to manually repair your bootloader. Change directory to E:\boot, where E: is your Windows 7 install DVD (check the drive letter):

cd /d E:\
cd E:\boot

Run the following command, where C: is your Windows Vista OS partition (check the drive letter):

bootsect.exe /nt60 C:

Then run:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Then restart your computer.

I hope this comprehensive guide is useful to you. If you have troubles during any step, tell us.

Linda here is a link that might put things into a better perspective on what might be the problem. http://pcsupport.about.com/od/.....issing.htm
also u should not see your bios at all when booting your vaio normaly, as soon as u hit the power button to turn it on keep tapping the F8 key, no F2 for bios entry, just F8 only.
