Hd Not Mounting :(


i was reinstalling OS 10.4 when there was a disc error half way through. after restarting the computer, the hard disc would not mount. i'm not quite sure what to do here, PLEASE HELP!!!
Did you happen to copy what the error said? If so, post it here so others can see what might be the case. Also post your system specs. Could possibly be a hardware problem.
Hold the COMMAND-'S' key while booting to enter the single user mode. Type 'fsck -f' to check your filesystem. Any errors? Did you try to enter your os in the safe mode holding SHIFT while booting?
Btw, welcome to the forum.
