![GNU GRUB Screen]https://i.stack.imgur.com/8S24N.jpg

99% of the time The first option is selected by VirtualBox in under 3 seconds, the other 1% it pauses for me to actually choose. No matter the option I choose, the next screen will be a black screen with an unblinking prompt and that's it.

Additionally, VirtualBox is being initiated via a vagrant up on Windows 7 via a cygwin commandline.

I'd appreciate as many ideas as possible, random spitballs are also welcome!

  • Is the guest 64-bit? Is VT-x enabled in BIOS?

  • And where is the box from? Did you download it or build it yourself?

  • Guest is 64 bit. Did not build it. It's a generic build for the firm I work for. I must add that it was built on a Mac OS

  • OK, boot your Windows machine into BIOS and check if the VT-x (or some "virtualization" setting) is enabled. Although normally VirtualBox should detect that and complain in the GUI...

Found out what the problem was. As embarrassing as it may sound, simply enabling Hardware Virtualization from the BIOS solved the problem

The blinking cursor can be a number of things. Are you able to CTRL + F2 to get to a terminal, or is it completely dead?

If you boot to a live cd and mount the hard drive, is your stuff on the file system?

Lastly, have you tried this? :)

  • After a few tries I got the screen back up and tried CTRL+F2 on the black screen. Nothing, no response, no change. I removed all files, did a cold reboot of the host and when I got back to the screen I chose the recovery mode option given the instructions in mount the hard drive . I got this screen and then it hung again. I'm hunting down straws as we speak
