iSCSI boot BSOD inaccessible boot device error Windows 2016

[#1]

Greetings,

We are currently working on getting Windows Server 2016 deploy via Microsoft Deployment Tool Kit but it seems that the OS is not able to access the boot partition per BSOD error code

We tried using Legacy and UEFI BIOS and still same issue. Change the Boot Policy to boot only single path on iSCSI boot, repair the MBR partition. Also tried with the latest driver version. Any help will be a great help!

Greetings.

If your vnic (or vnic template, connectivity policy defining the vnics) have MTU set to 9000/jumbo, please set that to 1500 for now.  I have seen some iSCSI BFS installs partially install but get corrupted when jumbo frames were enabled on the vnic (which gets auto detected with window installer) but fragmentation/dropped frames occur due to end to end jumbo not really being enabled.  If this happened to be the case, I would reinstall again/reformat the boot partition with 1500 MTU set.

That stop code error is frequently associated with boot device or boot file corruption issues.

Esxi only takes a few minutes to install, so you might want to use that as a test to confirm boot LUN & iSCSI connectivity are good, if the MTU is already set to 1500/default.

Thanks,

Kirk...
