How do i make correct partitions with grub 18 error?

[Gleno0h]

Well i got another system with 1 hd, nothing special and its 160gb
After i installed lenny, it couldnt boot and i had an error 18 message.

After looking on google i had to make a /boot partition of 500 mb and a swap with double the size of my RAM which is 512, and then it booted. But now ... man i cant even install jack sh*t.. /dev/hda1 is fully used on 100%.

Output 'df';

server18:~# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda1               474440    446875      3068 100% /
tmpfs                   127676         0    127676   0% /lib/init/rw
udev                     10240        88     10152   1% /dev
tmpfs                   127676         0    127676   0% /dev/shm
/dev/hda2               474472     19276    430697   5% /boot

And its 160 gb, no way its fully used after only an apt-get update upgrade and installing openssh ....

My question is, how can i use the full hard drive for ispc3?
cause i dont know anything about linux partitions.

This is the first time i had this and i just cant figure it out ...

Thanks.


EDIT
Nvm, its solved ... i forgot to give the other 100+ gb a location haha, fail.
