Why does virtualbox show only 32 bit option on 64 bit machine and 32 bit os doesn't work

Question

I have a 64 bit AMD computer and was trying to install Virtualbox. However there were only 32 bit options for creating virtual machines. I googled a fix and it said to disable Hyper-v and enable virtualization. I went to windows features to disable hyper-v, but it was already disabled. But as for the virtualization, I couldn't find it in the BIOS anywhere.

How would I enable virtualization?

Answer 1

The fix was to update the BIOS, and then to go the BIOS and enable the AMD SVM/ Intel VT-x setting. Now it works perfectly.
