Hi,I have got the unhealthy status error.One or more boot driver(s) have reported issues. Check the Driver Health Menu in Boot Manager for details. After following some instructions I get into the VD management and accidentally cleared the configuration. After that Virtual disk got erased. Does it wipe my data? Is there any way to recover it back? 
I have accidently deleted Virtual disk - R440 PERC H740
