I have a toshiba c55-a5242.Somehow it crashed and won't boot up.I tried the system resrore using the 0 method but all I get is no bootable disk then no media.Tried restoring using the 0 method but that doesn't work.I ordered a recovery disk was sent a flash drive.But when trying it with flag drive it runs but I get a screen saying system ran into problem looking for a solution and will restart for you.Can anyone please help?
