Jiiiiihah… I solved it by myself :))
Steps:
Entering the Setup of the Mainboard (UEFI/BIOS)

• CSM Support diabled
• network stack enabled
• leaving with saving and reentering the bios/uefing
• placing the right boot order in the boot menu (1. nic, 2. Windows10)

Preparing the DHCP Server with a new vendor class following these steps:
https://wiki.fogproject.org/wiki/index.php?title=BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy
I took PXEClient:Arch:0007 with the ipxe.efi for the Option67.
I did not change the refind.conf as mentioned here:

FOG Server:
Entering the Hostmanagement:
Host Bios Exit Type: none
Host EFI Exit Type: Refind_EFI

And now it works :)))

Hi,
i had the same problem with DELL Precision 3630.
no bootable device was found because the internal PCIe SSD was in Raid 0 mode.
I switched it to non RAID0 an then it works. But pay attention. I had to reinstall the OS.
Hope that helps.

Hello

root@fogserver:/datastore/images/dev# chown -R fogproject:www-data /datastore/images/
Now it works :)))

hi guys,
the compression rate in the image caused the error
capturing and deploying works…
Thx 4 the support
thread closed … finally

@sebastian-roth
good point…
I realized that i put the compression in the image section to the highest level (22 :))…
i will decrease it and i will try to capture again…

@bszadmin

@george1421 Thx 4 the reply
I will try and respond
Meanwhile i installed the little HP clients with an USB Stick and started a capture process.
It also breaks…

Does this info help in finding a solution? I hope
Sorry 4 the minor quality of my PNGs

Thx

@george1421
Hi again, I thought it is the image…
Meanwhile i tried to deploy several other images… Same problem.
At 90 % it breaks down.
Is it maybe a problem with the disk space?

Hi again,
i am trying to capture a win10 x64 image from a virtual machine (hosted by virtual box).
The image process starts normally but suddenly the current block section stops counting, the rate decreases an the remaining time increases.
A few minutes (sometimes hours) later the image process resumes for a short period an then the loop begins again --> current block section stops counting and so on

I am looking forward to your ideas.
Thx in advance
Greets

@george1421 Thx 4 the answer.
I tried to deploy the image to the machine i had captured … Same Error.
The image seems to be corrupt.
I will try again.

Hi guys,
thanks 4 the good support alle the years
I tried to deploy an image to my little HP x210 machines.
The deploy process suddenly stops at a high percentage rate.
Please look at the two images and give me a hint to go on.
Thx a lot

@sebastian-roth

We will update the server and see what happens.
Thanks meanwhile.

@sebastian-roth
Good morning, sorry for bringing up ths old topic.
The clients are HP x2 210 G2 as @Matthieu-Jacquart guessed.
The fog process stops here:

We are running fog 1.5.6 with kernel 5.10.50.
Thanks for the support and the great work.
