Hi,

Im trying to install Windows 8.1 (product/DVD codename: "WIN 8.1 X64 ENGLISH 1PK DSP OEI DVD"), but it fails with the following message:

Code: Select all

Your PC needs to restart
Please hold down the power button
Error Code: 0x000000C4
Parameters:
0x0000000000000091
0x000000000000000F
0xFFFFF8023BDBFA80
0x
Is there a way out of this, or am I stuck, until this OS will be officially supported by the VirtualBox?

1) 64-bit guests or any Windows 8* product need hardware-virtualzation enabled in the hosts bios.
2) when creating the 64-bit guest you must select 64-bit in General -> Basic -> version.
3) If running Windows as host you must make sure hyper-v or xp mode is not enabled on the host. MS does not play well and wants it all.

Change the VM Settings, General, Basic, Version. It should say "Windows 8.1 (64-bit)".

Perryg and socratis, thank you for your replies, which both, despite my initial expectations, indeed, were rather helpful :P
