4 golden rules apply (until you know exactly what you’re dealing with):
- DO NOT run ‘chkdsk’ or ‘scandisk’ or any other partition repair utility
- DO NOT use the Windows recovery console commands ‘fixmbr’ or ‘fixboot’
- DO NOT attempt to recreate a deleted partition with ‘Fdisk’ or ‘Disk Management’
- DO NOT change the contents of the disk or partition that needs to be recovered
