You can try PARTITION RECOVERY (google that) programs (but they need to run from a disc or USB-stick, since they can't run from Windows anymore).
If no luck, make a new partition and go back to your backup, or use the recovery options (recovery partition, recovery disc) your Lenovo laptop came with.
Now i don't claim to know a lot about pc's but ive known my way around them for a while.
i might have deleted the wrong partition on my pc and i want to know if there is a way to recover from it.
My hard drive is being detected in the bios so im not sure why it cant find my hard drive.
