Whenever Win 10 VM is started, it first drops to UEFI shell, requiring manual intervention.

Immediately after the VM boot-up, black screen with text "Press any(?) key to...??" (currently it's hooked to low-res TV, and the margins are cut off, so can't read the text completely).

No matter what you do there, you still end here:

 

UEFI Interactive Shell v2.1
EDK II
UEFI v2.50 (EDK II, 0x00010000)

Press ESC in <countdown> seconds to skip startup.nsh or any other key to continue.

Again, pressing ESC or any other key here won't do anything; need to type 'exit', after which land in BIOS:

 

Standard PC (i440FX + PIIX, 1996)
?c-i440fx-2.5

 

There I need to select 'Continue' from menu, and only then it boots to windows installation.

Edit: could it be, that https://lime-technology.com/forum/index.php?topic=39493.0 is still valid, and hasn't been fixed in a year?

Edit2: fyi, IIRC, the issue went away after the windows was installed; this problem occurred only during initial vm startup.  So I passed that screen as described, and afterwards it was okay when the vm was rebooted.

Just wanted to say I've got the same issue.

6.2.0-beta21

 

Thanks for the tip, typing exit I was able to boot to the Win 10 img.

I have this very same problem but typing "exit" and pressing continue simply loops me into Boot failed and getting the same menu.

Anyone find a solution to this? I see the same thing.

Doesn't seem to be anyone using it...or having the same problem.

I have the same issue with a Hackintosh VM - supposed to boot to the Clover bootloader.  I followed the guide to the letter that's supposed to work.

Same problem. Works fine when i use Win7 template to install Win10, but when using Win10 template this happens.

 

I want to use Win10 template cos it allows USB3 from the menu.

For the record, I have built at least a dozen win10 vms in the process of trying to get GPU passthrough working correctly. Here's what I have observed:

 

Usually no UEFI shell on startup. Once Win10 is installed (I've done Home and Pro), VM boots normally.

 

However, if I hard reset the vm a few times, something sometimes gets corrupted, and I begin to see this behaviour. In some cases, an exit and 'continue' from bios works, in other cases, it just loops over and over again and I wipe and re-install...

 

Not sure how helpful that is, but in my experience, it seems to be related to the hard resets... Maybe something is getting corrupted in the nvram?

had the same problem of dropping to Shell at the beginning of win installation procedure.

my solution was to change to another Windows ISO downloaded directly from microsoft.

I'm having this issue on several iso's, is there any fix for this?

even for the ISO you downloaded from microsoft directly ?

I've only tried ISOs from Microsoft,  I remain stuck in this problem

 

Posted from my phone, forgive any spelling errors.

 

 

I had the same problem using the downloaded Windows 10 iso, but I typed "exit", which took me to the BIOS and I selected the EFI DVD Rom drive (or something like that - it was the first boot option) and the install started.

So i'm experimenting with restoring VM's from one unRaid install to a different one on different hardware.  My primary unRaid system is running 6.1.7, the experimental box is running 6.2.4.  I've never seen the issue described in this thread before with 6.1.7 which i've used to host various VM's for the past year, but as soon as i touched 6.2.4, i hit this issue. 

 

Someone earlier in this thread suggested that he only saw the issue when using the Windows 10 template, i saw it with Windows 10 and with Win 2012 server.  I just installed Windows 2012 server using using the Windows 7 template and the problem went away.

 

Typing exit, and then continue did not work for me.  It just goes right back to that Shell command prompt. 

 

If you're hitting this issue, try installing the VM using the Windows 7 template, or try an older version of unraid.

I've found that using these settings appears to allow the VM to install normally.  Key is the SeaBIOS and SATA settings.

SeaBIOS seemed to do the trick for me, SATA was not required on my machine.

 

Thanks for helping me out poldim!

Hi

 

I had a similar issue , what I did was typed "exit" and then went to "Boot Manager" and I could not see my drive ... and I by chance selected "Misc Device" and it booted into my windows Partition. Hope it helps anyone with same issue.

I have much the same problem twice now, and both times from completely fresh VMs. 

 

My unRAID locked last night (I think related to the Radarr docker but thats another matter) and had to be rebooted. My Win10VM failed to restart and just displays UEFI sheell and (importantly) "map: No mapping found" so there is no Fs0: and no ability to get an bootx64.efi file running. It's like the EFI shell is wiped.

 

I'm really reluctant to wipe and re-do a 3rd time as it gets a crazy waste of time with all the config of Win10. Win10 ISO cannot repair this as its not a Win10 issue I think but related to the VM itself.

 

Any ideas? This happened 1st time on 6.3.5 RC3 and now on RC5 but I suspect nothing to do with RCs

I don't have any advice for the issue that you're experiencing at the moment, but I did want to make a suggestion.  I've taken to backing up my vm images  that I can restore them in case things go bad.  Theyre pretty easy to restore, even onto different hardware,

Hi There, I'm running MacOS HighSierra on a mid-2012 MacBook and I am trying to install Windows through the Oracle VM facility.
I have a similar problem as Tuxbass; I get the UEFI interactive shell:
 

BKL0: Alias(s):
      PciRoot(0x0)/Pci(0x1F,0x2)/Sata(0x0,0x0,0x0)
BLK1: Alias(s):
      PciRoot(0x0)/Pci(0x1F,0x2)/Sata(0x0,0x0,0x0)
Press ESC in <countdown> seconds to skip startup.nsh or any other key to continue.

I tried many solutions offered here and elsewhere, but when I get to BIOS to access boot manager, nothing happens.

simple fix is use seabios instead.

On unraid 6.6.3, that selection is grayed out when you select windows 10 template, you cant select seabios

Only if you edit an existing VM.  On a new VM you are allowed to change the BIOS.

That was it, I got it working with the SeaBios no problem.  Thanks
