Windows 7: Bios Access

Bios Access

Hi everyone;

I need your help. I am going to install 7, but, I have a problem during installation that I should disable AHCI mode. I found that I should go into BIOS. I have a Sony vaio laptop that I tried all keys like F1, F2, DEL, ESC, F10 ...Just F2 works and go to setup. In setup screen, I can see just main, security, boot and exit tabs. I don't know is it bios? If so, how can I disable AHCI mode? I didn't find anything.
Thanks in advance

Usually its the F2 key for the Vaio's if I'm not mistaken. Hold that down when you reboot.

I think you may need to enable Advanced options in the Sony Vaio BIOS
which may be locked by default for AHCI and other options.

If your machine has Phoenix BIOS, check out the following article on
how to enable/ disable AHCI in adavanced options:

Thanks for your help
I tried F2, but, as you can see in the image, it goes into setup. I want to know is it BIOS? If so, how can I disable AHCI?

Yes that is the BIOS.

You have to Tab key to the other options or use the arrow
keys as explained on the right hand side of your screen to view
the other options.

In your case, you are on the main tab and could use the arrow keys to
select the other options, again in your case, these are Security, Boot
and Exit.

Have a look at the links I have provided to see if they can
assist you in setting up the BIOS for your requirement.

What exact error did you get that said you need to disable AHCI in BIOS? When?

Where did you get Windows 7? Did you burn it to DVD yourself?

Please tell us exactly what happens when you try to install and verbatim error messages.

Thanks for help.
This is the whole story:
I have a vaio laptop VGN-FW 280J. I had a vista and Ubunutu on my machine. I had many problems with my windows and I decided to recover it. I used from recovery menu of Grub2 and tried to recover it. Maybe it was wrong. Anyway, I lost both ubunutu and vista. I tried to recover windows using recovery DVD. It did n't work. Finally, I decided to install windows 7. During installation, when it asked to where do you want to install windows? I found an error: "Windows cannot be installed to this disk. This computer's hardware maynot support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu." After that, I started working with command prompt and using disk part, I cleaned HDD and repartitioned and set it as primary partition and the formatted it. I thought that the problem has been solved, but, it is still remaining. In some forums, I found that if I can disable AHCI mode in BIOS, I will not have this error message. I tried to disable, it was unsuccessful. Becase my BIOS is aptio setup utility 1.23.1109 and it doesn't advanced menu. With this situation, how can I install windows 7?
Yes, I burned it to DVD myself.
Thanks in advance

Check for a newer BIOS update on Sony's Support Downloads webpage for your model.

Did you make your Vaio Recovery Disks before wiping the HD? I'd try running them first to see if Vista can be restored to it. You can then run Windows 7 Upgrade Advisor to check for issues and upgrade BIOS easier if needed.

Where did you get Windows 7? How do you plan to Activate it?

Confirm the ISO integrity then burn another DVD using ImgBurn at 4x speed, then boot it to Custom install, delete all partitions and click Next to let installer format and begin.

Try writing confirmed ISO to flash stick using Universal USB Installer with Windows 7 in dropdown menu. Boot under USB, Removable on HD's in BIOS setup Boot tab.

Try resetting the BIOS to defaults: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS. While in BIOS setup check every tab for SATA controller settings to find out current setting.

I believe I will leave you in Greg's more than capable hands Vahid.

Just found this (thanks to Bare Foot Kid) which may be of some use to you:

Vista, Windows7, Mint Mate, Zorin, Windows 8

Forget it - on a Sony you can do nothing with the BIOS - they restricted BIOS access by design. That was the one and only reason I just returned an otherwise superb Vaio and got my money back.

There was no way to set AHCI, no way to change the boot sequence and no way to run live CDs . the cursor froze.
