Hi All,

I have having a problem installing a 64bit (Windows 7) guest on windows server 2012 R2. Virtual Box doesn't seem to give an option for 64bit guests. Any ideas? THe host OS is 64bit.

Thanks

1) 64-bit guests 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.
