Windows Server 2008 R2 VM cannot up

My Windows Server 2008 R2 VM guest cannot boot up. It will keep on boot into the recovery console.

When I mount the VHDX file, I see that the drive file system become RAW instead of NTFS. I have perform checkdisk (chkdsk /r) on the affected drive. After finish the checkdisk, the drive is back to NTFS format.

But the VM still unable to boot into the Windows. I have mount the Windows installation ISO to perform the following:

1) startup repair

2) bootrec /rebuildbcd

3) bootrec /fixmbr

4) bootrec /fixboot

Please advise

Thanks
