Win 7 doesn't install properly on "Win 8 machine"

Hi,

here are some screen shots of the (I think relevant) parts of the BIOS, please advise if you want shots of different parts of BIOS.

Thanks,

Ken.

I don't see the Secure Boot choice on Security tab that's supposed to be there from Necessary changes in the UEFI Firmware (BIOS) for a successful downgrade from Windows 8 to Windows 7:

Enter the UEFI firmware (formerly known as BIOS) by long-press the F2 button and turn on the notebook. Go to the "Security" tab and change the value of the "Secure Boot" option to "Disabled"

Check again.

I also wonder why the UEFI boot choices don't appear in Boot Priority list which would be necessary to install in UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.

When you insert in the USB installer or DVD, do these show up as UEFI choices?

Are you setting the Boot Mode to CSM or UEFI currently? I would try both. The Secure Boot choice may only show up on Security tab if you have UEFI boot selected, so check that too.

Then try UEFI install in both UEFI and CSM modes, and if these fail set to CSM and try to Bypass UEFI to Install WIn7 which has worked in every case so far that UEFI problems become insurmountable.

Hi Greg

Cleaned up screen shots.

Thanks Ray:

Any theories on why Secure Boot may be missing from his Security tab?

Shouldn't some UEFI listings be there in Boot order?

Should he try both UEFI and CSM in those two settings which offer them, to see if Secure Boot shows up, whether DVD or Flash stick show up as UEFI boot options, or if he can install in Legacy bypassing UEFI?

Steps to Install Windows 7 on a Windows 8 Unit
On Satellite Pro C870, Satellite Pro L830, Satellite Pro C850, Satellite Pro R950, Portege R930, Portege Z930
it is called SAFE BOOT.

To downgrade from a installed Windows 8 OS to a Windows 7 OS, using a Windows 7 recovery media, follow these steps:

1) Boot unit and press F2 to get into BIOS

2) Go to "Security" tab and disable "Safe Boot"

3) Go to "Advanced" tab, select "System Configuration" then change boot mode from "UEFI" to "CSM"

4) Press F10 to save changes and exit.

5) Boot unit from recovery media (Press F12 on bootup to boot from USB or DVD media)

But in the above it is called SECURE BOOT.

If you want to install Windows 7 instead of Windows 8 you have to perform some changes in the UEFI firmware first.

1.Enter the UEFI firmware (formerly known as BIOS) by long-press the F2 button and turn on the notebook.
Go to the "Security" tab and change the value of the "Secure Boot" option to "Disabled"

2.Go to "Advanced" tab -> "System Configuration" -> and change the "Boot Mode" option from "UEFI Boot" to "CSM Boot"


3.Save and close the UEFI settings by pressing the F10 key.

If this steps are done, Windows 7 can be installed on the Notebook without any problems.

I would YES.

But the OP's screen shots are for UEFI & CSM.

YES.

OK,

thanks for all the help I will try what I can understand and then go for what Gregoker said about if it gets insurmountable!

cheers,

bye for now,

Ken.

Hi,

problem solved apart from the fact I cannot get on-line.The problem with video playback has been fixed,

FYI let me tell you how I managed to install Win7 "working"

As suggested I changed Boot mode from CSM to UEFI, this made "Secure Boot "disabled show up on the security tab. I tried to install from Win7 installation DVD and it started fine (although different from previous installs) when it got to "starting Windows" with the 4 colours moving around it froze! I tried this quite a few times and could not get past this point.

As suggested I tried Bypassing UEFI to Install Win7 ,I followed the instructions exactly and the install seemed to have the same problems as the previous bad installs, when I tried video playback however it worked perfectly, this brought to mind what Faladu posted-Windows 7 fresh installs will usually (closer to always actually) require some 3rd party driver installs before it's really done.

It got me thinking that drivers were missing that I needed to connect to the internet.

It will be a while before i can afford an Ethernet cable(just paid of a massive credit card bill!) ,then I'm sure I will be able to go online and get any missing drivers.


I posted this problem to Windows 8 forum where theog kindly replied, can theog explain over there how my problem was solved before I mark it as solved?

many thanks to everyone for the help!

Kindest regards,

Ken.

EightForums thread:
How to reset BIOS for new HDD

Some OEM manufacturers are locking end-users out of the options in UEFI/ BIOS firmware on consumer PC’s, to install other OS's in UEFI mode, so you can only install Legacy mode, on business PC’s there not.



Windows Hardware Certification Requirements for Client and Server Systems

Microsoft said:

Mandatory. On non-ARM systems, the platform MUST implement the ability for a physically present user to select between two Secure Boot modes in firmware setup: "Custom" and "Standard". Custom Mode allows for more flexibility as specified in the following:

It shall be possible for a physically present user to use the Custom Mode firmware setup option to modify the contents of the Secure Boot signature databases and the PK. This may be implemented by simply providing the option to clear all Secure Boot databases (PK, KEK, db, dbx), which puts the system into setup mode.

If the user ends up deleting the PK then, upon exiting the Custom Mode firmware setup, the system is operating in Setup Mode with SecureBoot turned off.

The firmware setup shall indicate if Secure Boot is turned on, and if it is operated in Standard or Custom Mode. The firmware setup must provide an option to return from Custom to Standard Mode which restores the factory defaults. On an ARM system, it is forbidden to enable Custom Mode. Only Standard Mode may be enabled.
