Virtualization suddenly gone? 64bit guest / 64bit host (VirtualBox)
Hopefully somebody here can help me. I've looked around everywhere to find a solution for this issue, but this problem differs from all the threads you can find in many forums around there: it already worked well for me
My problem:
I want to run a 64-bit virtual machine with VirtualBox on my 64-bit host OS (Win 10 Home).
When I created the VM, there was already an option for 64-bit guests in VirtualBox settings, so I installed Windows 64-bit and everything was fine.
Now, apparently after uninstalling McAfee Internet Security with the official Removal Tool, I can't start my 64-bit VM anymore. (but I can't find any McAfee related solutions on Google as well) Instead, I get errors that say the 64-bit guest 'will not be able to boot', Hyper-V virtualization errors, etc. - no wonder, the 64-bit option is suddenly completely gone, when I take a look at the VirtualBox settings. Therefore I can't create or use any 64-bit VM anymore.
After searching for solutions for many hours I have to add the following:
There was never an option for Hyper-V under 'programs and features', I guess because I use the Home edition of Win10 which doesn't include Hyper-V.
In my BIOS there is no option with virtualization, VT,... or any similar option. I googled and it seems like my Acer notebook would enable it by default but locks the option to disable it in the BIOS (like I said, it already worked perfectly)
I can't even get my files from the virtual disk image, because only a 64-bit guest OS can boot with it - afaik. If I could get the files out of there, I would just create a new VM with 32-bit and restore my files there to use it in 32 bit mode.
any more ideas?
edit: I use avast security now, but I don't think this is the problem.
