I made a mistake by accidentally formatting a drive that a customer’s data was on. I was able to recover a 451GB partition with their files, and now begins the real challenge.. Getting it to boot back up.
Windows 7 100 MB system recovery partition missing prevents system from booting.
Can’t boot after deleted System Reserved Partition
Missing system partition – Google Search
