Invalid GPT table

completing fast and rebooting without uploading the image to the FOG server.

What version of FOG? what model is the target host? Can you provide a photo or video (via YouTube) of the errors?

[DarkEnergy]

The last SVN that was available for at the time: You are currently running version: 7162
I don’t think the model of the target host is a valid information as I have tried it in a Lenovo Touch B-50 and HP 15-R030WM and they are both doing the same exact thing. Is GPT now supported by FOG? Last time I encounter this error Elliott was explaining GPT issues and that was difficult to make it work.

I am not sure about the video part as, the screen move pretty fast but, I will try to see if I can get something. Is there an error log in FOG that I can pull it out from if possible?

@DarkEnergy The upload and download scripts have been re-written to better handle partitions and GPT disks. It’s vastly improved over the old scripts.

Do a debug-capture, and when you get to the shell prompt, issue the command lsblk and then fdisk -l and take a picture of the results. The output of lspci would also be helpful, so we can determine if the hardware in the device is supported by our current kernel build.

Info on the Lenovo from a Google search:

a 2TB and 7,200-rpm hard drive with an 8GB SSD

@DarkEnergy Wayne is perfectly right. How could we be able to help you without knowing the exact error message you see?? It’s impossible - as simple as that!

Tried google with “invalid GPT table” and it might be this error caused by gdisk: “Found invalid GPT and valid MBR” but it’s just a wild guess…

iPhones can do slow motion videos and even if you have a different phone a bad video usually gives more information than no video. Make sure you mount the phone properly to minimize movements (e.g. just put a couple of books on the desk in front of the screen and rest the cam/phone on the books while taking the video).

@Wayne-Workman:
The odd part is that only those two laptops are having the issue even after disabling UFI on the system. I ran into this problem before and a low-level formatting was the solution. However in this one, it is still a no go.
Both systems have been LLF and Windows has been reinstalled.

I will run the debug and see what information I can accomulate.

@Sebastian-Roth
Thank you for pointing the obvious but as you can read below, if the systems have been LLF and GPT disabled in the BIOS, then, there should be no GPT table in the HHD. The system came originally with Windows 8 and was downgraded to Windows 7. Last time I ran into this problem I had to download a new collection of PXE files for the TFTP Server in order for the system to be able to boot into FOG and upload the files.
I have tried everything I know including updating the trunk to the latest version.

As I mention on the initial post, the system were LLF, meaning nothing was on it at the time the image was been uploaded to the server. No trying to be rude just providing some information.

[sudburr]

How did you LLF?

[Sebastian Roth]

@DarkEnergy Definitely valuable information you gave us but we still need a straw to cling to - the exact error message! I am sorry but I am not willing to further look into this issue unless I know the error you are seeing when things go wrong. No offence!

[Tom Elliott]

@DarkEnergy just my guess, but did you try running fixparts on the upload before it uploaded? Seeing as the systems were originally set up for uefi and you turned it off, it sounds more like it simply had “bad gpt info” as UEFI requires a gpt layout. When you made the switch, from what I can gather, you set the host to use mbr style layout by just changing the info in Windows. The LLF in this case, I think, would be more using fixparts to correct the particular issue.

As requested, here are some screenshuts after running the commands in debug mode:

Please let me know if you need more information.

Here is another error after uploading an image for a Lenovo Touch B50-30.

[Sebastian Roth]

What about gdisk -l /dev/sda??

[DarkEnergy]

@Tom Elliott
I ran the test and it was successful. I was able to copy a file from my system (Windows 10) to the FTP in the fog server, then I was able to delete it as well.
I am not sure what was the test for other than to make sure if the access to write and delete are in place and the service is working?
For this so far so good.

[DarkEnergy]

@Sebastian-Roth
Is there a specific option do you want me to run after running gdisk -l /dev/sda/?
I am getting a menu that is all.

[Tom Elliott]

@DarkEnergy what are the permissions for /images?

Can you, from debug, run fixparts /dev/sda then run fog

[DarkEnergy]

@Tom Elliott
The directory has the following permissions:
drwxrwxrwx 2 root root 16384 Dec 11 17:16

Will this be for the Lenovo or for the HP or for both?

But did you use the credentials you found inside of Storage Management - > Default when you tried? Because in the screen shot below, it clearly says “login incorrect”. that’s a pretty clear error.

Also - I just added notes to the FTP Troubleshoot article about what credentials to use when doing the tests.

What I was aming for is the output you see before the menu. I should say something like “Found MBR”

@Tom Elliott

Thank you, Tom the fixparts command fix the GPT issue.
I will try to do a system with full GPT table and see if it upload.
