Hi, I am trying to get Virtualbox set up on my Windows 10 host with Ubuntu 14.04 as guest where Ubuntu is accessible through both the Grub boot screen during computer boot and through Virtualbox. I am able to boot into Ubuntu with a reboot, it's just when I try to boot Ubuntu in Virtualbox, all I get is a black screen with a solid cursor. It does not respond to any keyboard shortcuts.
I have this working already on my laptop, but that computer uses a Windows 7 host (I followed a guide to do this, but cannot post a link since this is my first post). I suspect the issue is with the UEFI BIOS on my Windows 10 computer but I can't figure out how to fix it. A lot of what I've read to try and fix this relies on being able to get to the Grub boot screen, which I cannot. Any suggestions on what to try? Log file attached.

Re: Ubuntu boots to black screen with solid cursor - W10 Host
Just to be clear: you have a native Ubuntu boot (dual boot) on your PC, and you want to run that native partition inside a VM when you boot into Win10 - is that correct?
The first thing I'd confirm is that you have the necessary permissions for sector level access to that partition. Speaking of which: is the Ubuntu partition on the same physical drive as Win10, or is it a different drive?

Yes, I have native dual boot already set up and wish to boot that drive inside a VM in Win10.mpack wrote:Just to be clear: you have a native Ubuntu boot (dual boot) on your PC, and you want to run that native partition inside a VM when you boot into Win10 - is that correct?

Are you referring to the permissions Win10 sets on the drive? If so, I have already taken the steps with Diskpart to set the drive as read-only. The Ubuntu partitions are on an entirely separate drive from the Win10 partitions.

I would check to see if SecureBoot is causing this issue.

Re: Ubuntu boots to black screen with solid cursor - W10 Host
Was that a mistake in your answer? Because if it wasn't, that's your problem. You cannot have a virtual machine as a read-only filesystem, unless it is specifically designated to do so (Live CD).seanohue wrote:I have already taken the steps with Diskpart to set the drive as read-only.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

It is already disabled in the BIOS.Perryg wrote:I would check to see if SecureBoot is causing this issue.

Re: Ubuntu boots to black screen with solid cursor - W10 Host
I figured it out. I made a grub boot ISO following this guide: viewtopic.php?f=6&t=66583 I boot from the ISO and check "Enable EFI" and I am able to get to the grub boot screen! Only thing now is that when Ubuntu is booting, it says "/boot/efi/ not ready or present". If I press S to skip mounting, I can get into my Ubuntu desktop and everything appears to be working. I found something that might fix that message, but I'm hesitant to unmount /boot/efi/ because I think that may cause problems with native boot.
