I have enabled the Hyper-V feature in Windows 10 and created a Windows 7 virtual machine. I need to boot VM into safe mode for troubleshooting issues, but could not find a way to get that. When I started the VM from the hyper-v manager and press F8 key repeatedly, it just boot into my desktop normally. It happens on my Surface Pro 4 and a Toshiba laptop. How can I resolve the problem?
You might could not get the safe mode menu with hyper-v virtual machine on Windows 10 or 8. Because the boot process fails to materialize or the F8 keystroke can not be responded in VM. You could try the solution below to make changes and fix the issues.
All created Hyper-V virtual machine has setted the Automatically start delay time to 0 by default. If you would like to start Windows OS into safe mode, you need to modify the delay time.
* Open Hyper-V Manager, right click the VM that you need to configure, and select the Settings option.
* Under Management in the left pane, click on “Automatic Start Action and then enter the Startup delay seconds”.
* On its right pane, check “Automatic Start if it was running when the service stopped” box, and change the start delay time from 0 to 5 seconds, then click OK button to confirm.that.
However, the F8 from keyboard may not accept the EULA, so you can not press this key to get into the virtual machine. It is easy to set it to use the Fn key or F-Lock key for that. If it is still not working or your laptop doesn’t have an F-lock, using the Ctrl+Shift+Alt+F8 key combo resolve the problem.
