Kernel Panic - Couldn't find valid RAM disk image

[ahmedabm]

Hi all,
I’m new to The FOG and I’m getting
Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(1,0)
as shown in this image

I tried different Kernels including 6.6.49, 6.6.69 all failed with the same error…
Interesting, the only Kernel that worked was version 4.19.145 but this kernel lacks newer Network drivers so it doesn’t work for all models. Tested this with different DELL models including OptiPlex Small Form Factor 7020 and also tested with VMs… All getting this same Kernel Panic Error.
Also Noticed these warnings in the previous screen (after loading init.xz)
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID as shown in this screen:

Not sure what is the difference between Kernel vesion 4.19 that is working and the newer ones.
We are running the FOG version 1.5.10.1629.

Thanks
