Unable to update boot.ini on the destination machine's system volume - Failed at 98% trying to convert phisical Win Server 2008R2

hi all

I'm having the problem on the object

I've search enought for same problems but everybody get the error while trying to convert windows server 2003 - I also found that 2008 doesn't have a boot.ini ( Boot.ini in Windows Server 2008)

So, how can i solve my problem? I don't want to create a boot.ini file with the risk to impact the server funcionality

I attach the log file

thank you all
