That's very confusing.
Your earlier screenshot showed just one HDD attached to IDE0, i.e. not a SATA HDD
The repair feedback talked of sda, the first (presumably only) SATA HDD, and now your latest screenshot shows sdb, your second SATA HDD.
Perhaps we'd better get back to square 1.
Can you explain what problem you had that made you start trying to repair the boot, and how the problem occured.
Also, look around further with the partition manager and see what it lists on sda.
The FAT32 partition is your Acer factory reset partition, and by repairing it with a 3rd party tool, you'll have lost the custom bootloader which controlled the Acer recovery system.
