Sanboot Win7/8/10 after cloning disk on same Hardware

[albrecht]

Hello,

I want to boot an already installed operating system via iSCSI. I succeeded in the virtual environment. I have a VM as a PXE server and a VM as a client. I have installed Windows 7/8/10 on the client. Then I cloned the virtual hard drive with Clonezilla on a blank virtual hard drive in the PXE server. I then included this disk as an iSCSI target. I was able to boot successfully. My configuration is:

Code:

dhcp net0 && echo IP address: ${net0/ip} ; echo Subnet mask: ${net0/netmask}
set gateway 0.0.0.0
cpuid --ext 29 && set arch amd64 || set arch x86
set boot-url tftp://x.x.x.x
set keep-san 1
set initiator-iqn iqn.bablaba:test
sanhook iscsi:${next-server}::::iqn.blablabla:testimage
sanboot

My problem is, why i can not realize this on another real Hardware client? When I try to boot the iSCSI-Image from my physical Client the pxe process succed and one can see the loading windows logo. But after 5 minutes a bluescreen comes with the message "inaccessible bootdevice"




Can somebody help me to solve this problem please?


I used ipxe.lkrn and have deactivated UEFI. Furthermore, my bootimages are based on BIOS
The PXE-Server has the OS Ubuntu 18.04
The sanboot works in the virtual environment. I can boot windows 7, windows 8 and windows 10



Best regards
