S205 & Win8 - How to force legacy BIOS mode?

2012-09-13, 8:09 AM

Hi,

as far as I know the S205 has got two different interfaces:
UEFI and legacy BIOS.

Windows 8 supports both.
Using UEFI, Windows will partition the drive with GPT.
Using BIOS, it will be done with MBR.

The main problem is that - probably due to malfunctioning drivers - there are some major problems when using GPT with this netbook. You can find numerous threads about not working WiFi cards for instance.

What I'm looking for is an option to boot the Windows 8 installation through the BIOS interface from a thumb drive.
The S205 hasn't got an optical drive and I haven't got one either.

Thanks in advance for any help.

 

PS: As this is not a driver issue, I'm not posting this in the Windows 8 forum.

After doing some research, this is how to successfully use the Ralink Wifi with Windows 8 on the s205 - clean USB install.

You must install Windows 8 in legacy mode (choose "IDE" in the BIOS).

BUT - you must *also* remove "bootmgr.efi" and \efi\ from the USB, before you install. If you don't, the USB will still install in EFI!

If you already installed Windows 8 in IDE mode from USB, you must check if your install is IDE/legacy or EFI - open this log file:

\Windows\Panther\setupact.log

Look for this text:

Callback_BootEnvironmentDetect: Detected boot environment: BIOS

=you have IDE/legacy install

...or

Callback_BootEnvironmentDetect: Detected boot environment: UEFI

= you have EFI install

(This information is from http://forums.bit-tech.net/showthread.php?t=209045)

If you see EFI/UEFI in the log file, you must reinstall Windows 8.

The only problem I have now is that Windows is freezing sometimes, so I plan to reinstall from a different USB in case of file corruption etc.

Hope this helps.

Hi rpiaggio, thanks for the help. Sadly this solution seems to apply to users with an external optical drive who can perform an installation from DVD. There must be a way to do this with a flash drive.
