Unable to create VM - Just boots to UEFI Shell

Good afternoon...  I've been using Unraid for several months, but was never able to try VMs because of using an old MB/CPU.  I've

recently bought a newer machine with 16 cores and 256Gb ram and installed Unraid on that machine as a trial (leaving the old Unraid

box on-line)...

 

I've followed the guides on Lime Tech, but when I try to create a new VM (Windows 10), I just get booted to the UEFI Shell and it leaves me

there...  The ISO I'm using for Windows 10 was just downloaded from MS a few days ago.   This is where I am getting stuck:

 

 

I know I've gotta be doing something wrong, but I've verified my Bios for Virtualization, used a fresh ISO, verified my file paths, but I'm not sure where to go next...  In part of my trouble shooting

I've try just using CPU0 or a combination of other CPUs in the VM template, but everything still just leads to this shell...

 

If I do a ctrl-alt-del from that shell's window, the shell reboots, and offers a "Press any key to boot from CD or DVD..." but if I hit a key, all that happens is a reboot, and that option returns.  If I

don't hit a key, that's when I'm left at the shell...

 

Thank you...

I guess you wrote "exit" and pressed "continue" and it didnt work as well?

in my case I did have the same situation and I downloaded a different WIN10 installation ISO and it worked.

Also, I can tell you that it helps to shutdown the power fully to make things work. I had a resolution problem in the bios OVFM and the GPU didnt pass through at all in the OSX. worked on it for a week on a system that I didnt switched off for 2 weeks. turned the FU#%@#%ing power OFF and ON and what do you know?! the shit worked immediately.

I guess that if you wrote this, you've been waiting for 30 min....:)

 the important point is you now are booting to the WINDOWS ISO.  any issues are most probably to do with the ISO itself.  unless you didnt configure the VM parameters correctly.

I am not very knowledgable, but I can tell you that if you follow the instructions and even youtube videos you should be fine.

I had what sounds like this problem with my Windows ISO.  I used YUMI to create windows boot disk on a thumb drive and pointed it at the ISO I was using.  OVMF VM booted just fine to the flash drive (SeaBIOS worked without having to do this).

I have been having this issue with this same thing. I've downloaded multiple versions both from the Microsoft page, torrent, and even ripped it off another working copy I use to install onto computers and all I get is what is showed in the image. I hit exit, it takes me to a bios style screen and then continue brings me right back to the same screen... help.

 

*****So after trying a Slackware iso I got the same screen. So this has to be something in the unraid software and configuration

I think I have found the solution to this from another post I read.  This worked for me perfectly.   When building your VM, Before creating it select BIOS to SeaBIOS instead of OVMF. By making this change fixed my boot up issue. Hope this helps guys

I am facing the same issue. I have created two Windows 10 VMs a few months ago and worked flawlessly. Now, this no longer works and I only got the shell upon startup / creation. I need to use OVMF, so switching to Seabios is not a solution. Also, exactly the same computer with same files worked before flawlessly with this setup. The only difference I can think of is that I upgraded to the 6.4.0_rc15e. Could this be the issue? Any thoughts appreciated!

I have solved it myself. I changed from i440fx-2.10 to i440fx-2.9 and things are working now. Any disadvantage of 9 vs 10? Any thoughts why this is not working with i440fx-2.10?

If you type "exit" in that windows access to BIOS and check BOOT options where you can run from there.

I have the same issue and could boot fine from BIOS.

Type this at the console:

fs0:

cd efi

cd boot

bootx64.efi

 

Should boot then.

If you are getting the UEFI shell when trying to boot a windows 10 iso you may just not be seeing the prompt to hit a key to boot from CD/DVD.  It is a pain to start a VM then launch VNC in time to see it.

Is there a permanent fix for this?  Seems this has to be done every time on certain VMs (ie. MacOS VM).

Here is a tip from:


Create a file called startup.nsh in the root of the flash drive which contains the single line below:

\EFI\boot\bootx64.efi
