ya i had a look at the bios and it the same result (1 drive only) The missing drives were D and E drive(both are from a same drive but i partition it) Only C show up.
P.S. :i also try system restore but it indicate that "Changes made to drive(s) E: D: after this point cannot be reversed because the drive was either excluded from system restrore monitoring, or was turned off or removed "
