Converted VM won't boot

VM won't boot on esxi 6.0 host. I uploaded the installation media iso to run a repair and the command prompt is showing me it found no Operating Systems when running the bootrec /rebuildbcd command.

I aslo tried SFC.EXE /scannow /offbootdir=c:\ /offwindir=c:\windows      ...which said corruption was detected?

We converted this vm from a 6.5 esxi host using vmconverter.

We don't have the vm it was originally converted from.

If it does not boot, it was not converted correctly, so you have to assume the VM you have may also be corrupt.

What options were used during the conversion ?

What is the Guest OS ?

What is the error ?

Please describe, what happens, when you power on the VM ?

It was converted from a powered on Server. Guest OS is Server 2008. Can't remember the exact settings but i don't believe i did anything differently from other converts that have worked.

When i power on the VM I get "Windows Error Recovery" and can pick one of the options (Start normally, last good config, etc,) None work. I get the windows loading bar followed by black screen and then back to the "Windows Error Recovery"
Possible Registry Corruption.

If you need the data from the server, connect the virtual machine disk to another VM helper.

Corruption being detected is a worrying sign, the disk is corrupted, which is restore from backup.

Have you tried safemode or tried to boot from Windows ISO and tried startup repair?

That was my fear Andrew. I'll look into mounting it to another VM and going from there. Have a link handy? if not i'm sure i can find one.

Murali, yes i booted it to an iso and ran startrep.exe as well as trying safe mode. All ended up with the same results.

Yes, it was much simpler than i expected.

Edit settings on good VM you wish to add the disk to, Existing HD, find vm folder in datastore popup, add.

Thanks for your advice.
Use chkdsk to check for corruption, if any exists, also check files can be opened, if any txt or word documents.
