I have changed the setting in BIOS from IDE to AHCI because my SSD was running slow, but now neither my HDD nor may SSD are recognized in BIOS and Windows recognizes them as Flash Removable Drives. My computer is running ok, even better, but i don't understand why BIOS can't see my storage drives.

Change it back, you will need to reinstall your OS if you change from IDE to AHCI.
I didn't need to reinstall the OS when i made the change, because i made the necessary changes in the registry of windows.... so it all functions properly, just the fact that bos does not see any of the HDDs.
