Hi,

I cannot boot RedHat 9 (which is the only OS installed on my harddisc). I inserted a Knoppix CD and mounted that hard drive. The command df tells me that the disc is 100% used (no free space at all)! I guess this is the reason that RedHat cannot boot. using the menue that comes up after rightclick on the hard drive icon, I gave permission for writing onto that drive. However, I cannot DELETE any data that are on that drive, because Knoppix prompts that I have no permission for that. I cannot swich to any of the users or the root of the RedHat system (i.e. those users that own the files that I want to delete). Of course Knoppix doesn't know those users.
What can I do? HOW CAN I DELETE DATA ON LINUX USING KNOPPIX?
