Solve the Problem of black screen on Ubuntu and black screen on ubuntu.

Virtual Box + Ubuntu 64bit can be used well before, but when it was opened yesterday, a selection interface (which of the following recovery modes is available) was black, and the cursor in the upper left corner was not flashing, stuck there, and later found the cause.

 

1. First download LeoMoon CPU-V check virtualization opened not, if the following is a Red Cross that did not open.

If it is a Red Cross, continue to look down. If it is not a Red Cross, jump to the third step to see if it can be solved.

2. Control Panel-programs and functions-enable or disable Windows functions, and then disable Hyper-V.

3. Restart and then open the LeoMoon CPU-V to see the following Red Cross turned green hook no. After changing the settings, check the virtual machine settings and make sure you select Ubuntu 64bit.

After running your Ubuntu 64-bit, make sure the following V icon is lit.

After completing the above steps, you should be able to start normally. This step is taken to solve this problem. If you encounter this problem, try again.
