Blank Screen with Blinking cursor in top left corner
-
We are having an issue, we get a black screen and blinking cursor in the upper left corner after the Fog splash screen to boot to Hard Drive. So far it is isolated to Dell Latitude 5570’s that we have been able to identify. We have different models out there, Dell Latitude 5530 to 5590. If we ESC past the pxe-boot it will boot to Windows like it is suppose too.
Fog version: 1.5.5
bzImage Version: 4.19.6
bzImage32 Version: 4.19.1 -
Ok just to be clear, you can pxe boot into fog ipxe menu fine and you can image fine, but when you pxe boot into fog ipxe menu and then let it timeout to where it should boot from the hard drive you get a black screen with a cursor?
If so what is the default exit mode for uefi (found in the fog settings->fog configuration menu)? It should be rEFInd for uefi based systems.
I do find it strange that the 5570s have issues with the 5590s don’t.

That is correct, also I verified the “default exit mode” and it is set to REFIND_EFI. Would a Windows, bios or driver update have this affect?

The short answer is no. Older firmware on the target system might. So just for additional clarity the 5570 is in uefi mode? If so then we have an issue with rEFInd executable not finding the disk controller. When the FOG iPXE menu exists it calls refind to locate the hard drive boot device to boot the target computer.

Apologies for the delayed reply I am off on military duty with limited internet. They are set to UEFI mode, how would I go about getting a resolution on the rEFInd exe not finding the disk for 1 specific laptop model?

@Brad-Schumann The short answer is it depends on what the laptop is doing. The bit longer answer is the config file for refind is in /var/www/html/service/ipxe and its called refind.conf.
Also make sure the firmware is up to date on this laptop because it could be flaky firmware that is causing refind to fail.
The last option is we may need to look into updating refind to a later version because the hardware drivers in refind may need updating.
So in the end it depends…
