7899，7963，7997 can be started on VirtualBox with UEFI enabled
That means that Windows 8 7899 is the first build to support UEFI w/o CSM, but I need to verify it first UPD: @yescn , could you send me proof of successfully running Windows 8 7899 on VirtualBox with UEFI enabled? Because I am not going to spend many hours to download Windows 8 7899 just to test if it is UEFI class 3 capable or not
I sill try 7889 if i can find it
Did 7899 work for you on UEFI class 3?
Wasn't able to find iso link with high speed download
Try Free Download Manager in order to fast download files from archive.org
I will try internet download manager
And... does you have downloaded 7899?
7899 didn't boot on UEFI Class 3.
Ok, then try 7904 Server (on UEFI class 3 PC), 7927 and 7955 x86 (on VirtualBox with UEFI enabled, but however, you may need to manually install it via deploying install.wim, because only 7927's install.wim leaked, and 7927 iso in the internet uses Windows 7 RTM x86 PE, which is not compatible with UEFI at all (does not matter that UEFI with or without CSM)), and 7962 and 7963 x64 (optionally try x86 version of 7963)
Nevermind i got it to boot!
But i cant install as no USB drivers
Try to install it from Windows 8+ PE, and BTW does 7899 boots with Secure Boot enabled?
How will it help? I still won't have USB after that
Try to install it from DVD if you have it, and Windows 8+ have built-in USB 3.0 drivers, but... stop, USB 3.0 drivers was introduced in Windows 8 7814, but maybe it not compatible with your USB 3.0 controller, but... if you have only USB 2.0, then... still try to run 7899's setup from Windows 8+ PE
My PC doesn't have DVD
I will try to integrate drivers from Windows 7 or 8
Windows 7 drivers might be compatible with Windows 8 7899, but Windows 8 drivers... I don't think that it will work with 7899
I used generic USB driver ported from 8 to 7 and it worked and i installed the beta on it on UEFI class 3 laptop
How to give proof
