Hi - you seem to have a "one host - one local disk" setup with just 2 VMs.
In such a case the most straight forward approach is to get a USB-boot-stick and then re-install the version that you used before you started to experiment with drivers.
The only thing you have to care about when doing that is to make sure you select the USB-stick when the installer asks you where you want to install the new system. Also make sure that you select "keep existing datastores"
Should take about 15 minutes. After installation you reboot and then the original datastore will most likely be automatically mounted.
In case the datastore really was damaged - and can not be mounted - we will give you commands to find out more later.
For now I think a new install to USB-stick is all you need.
