Hi Guys, I am new to this thing and I messed up something, I replaced my CPU after that my windows VM stopped working, I thought well, I will delete it and create another one.

After creating the new VM I am unable use my GPU because it is being used by the VM which no longer exist (well that is what I think).

Sorry if I posted it in the wrong place but it is my first post. 

Thank you for help!

gpu is in use by something else even if attached to vfio, most probably efifb, add this to your syslinux configuration:
 

video=efifb:off

 

Sorry but, I am a noob, Where in the file do I add it? does it need to be in a specific place or just add it to the end of the file?

I did google it but couldn't find it.

 

this is the file right?

default menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label Unraid OS
  menu default
  kernel /bzimage
  append initrd=/bzroot
label Unraid OS GUI Mode
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui
label Unraid OS Safe Mode (no plugins, no GUI)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label Unraid OS GUI Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui unraidsafemode
label Memtest86+
  kernel /memtest

 

Thank you

 

 

see here:

default menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label Unraid OS
  menu default
  kernel /bzimage
  append initrd=/bzroot video=efifb:off
label Unraid OS GUI Mode
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui
label Unraid OS Safe Mode (no plugins, no GUI)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label Unraid OS GUI Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui unraidsafemode
label Memtest86+
  kernel /memtest

 

Start "Unraid OS" (no gui) and that argument will be applied.

If it doesn't work attach diagnostics

 

I suggest to modify it from the unraid gui not the file:

Main - Boot Device - Flash - Syslinux Configuration

 

Modify the append line (all in the same line) of label "Unraid OS" like this:

append initrd=/bzroot video=efifb:off

and save and reboot.

I had to do it in the file because, I am not at home, but it worked. 

Thank you for your help and have a nice day!
