Don't bother installing the OS, just start the guest until the 'Fatal No bootable medium' error appears, then close the guest window with 'Power Off' chosen. Try Virtualbox 6.0.14, make a new 32-bit XP guest. See I have a 64bit host, but can't install 64bit guests. However, if your BIOS does have VT-x / AMD-V on, there's other things that take it before Virtualbox can use it. If you use 6.0.x or earlier, (or maybe it was 5.2.x and earlier) you can run 32-bit one-core guests: Windows 7 and earlier, probably similar restrictions to older Linux.

Beginning with 6.1.0, Virtualbox requires VT-x / AMD-V for all guests regardless of bittedness or core count. If you truly cannot turn on hardware virtualization, then you can't run Virtualbox 6.1.x & later. Did you contact the motherboard's manufacturer? Some BIOS & UEFI makers have taken the common 'everybody wants VT-x' as an indication to just turn it on and have no setting to modify it.Īlso, I have seen recently that AMD mother boards call it 'SVM' (if I remember right?). If it is a very modern motherboard, the hardware Virtualization (VT-x or AMD-V) may be on already and no switch to turn it off.

We don't yet have enough info to know what host PC you have, but there's two things that may be pertinent. Sorry for mentioning the video card, it's not pertinent to your issue, my brain must have been in a different thread.
