Restoring VM settings

Hello Everyone,

I've been running Server 2012 Datacenter on ProLiant DL380 G7 but this the second server to fail(after restarting the server boots but doesnt boot completly it hangs) and i've had to reinstall the OS and attach the VHDs afresh,

1. Is there a way of copying previous HyperV settings and importing them to the new HyperV installation?
2. which key do we press to launch startup repair on Proliant servers?
