As long as you only use the CD, you shouldn't even need to mount the Windows disk. Booting from CD would be a case of setting your BIOS settings to boot from CD first (if that's not the case already), then inserting the CD, and boot the machine...
Of course, using the "Live-CD" also means that you can't save anything form your Knoppix...

Thats ok. I just really wanted to try linux out before I saved it to my harddrive. I want to know if it's as good as everybody says. I think the part that sounds best to me is the built in C compiler.
I've used Knoppix on a couple of computers, never had any problem.
At least in the older versions I was using, disks, if mounted, defaulted to read-only. Hopefully this is still the same. Didn't mean you couldn't change that behavior - you could ask it to mount a disk read/write. (I never did this for an NTFS disk though, only HPFS and FAT32. (and Samba shares))
So, you can save things from Knoppix.
I mounted an NTFS disk readonly once in a (vain) attempt to recover data...
Fun CD, overall.
It's not "built-in", it just integrates nicely.
Remember Knoppix is primarily a "CD" distro, that's made to be run of a CD and not really installed. You should try various other distros... perhaps; Ubuntu, OpenSuSE, Fedora, Arch, Slackware etc.
Ok. I am very stuck. I can't get knoppix to run and I have tried many things. I am running Vista on an HP laptop. Any suggestions?
What happens? You're going to need to tell us what goes wrong... kernel panic, what?
To start it, generally, you insert the CD, and reboot. You'll need CD to be before your hard disk in your boot order, which is usually found in the BIOS settings. If your computer doesn't start booting windows, and brings up some sort of Knoppix-ish screen, this is correct. This screen accepts boot parameters, if you don't touch anything it'll use the default after a few seconds delay.
Nothing: windows just starts as usual.
Do you know how to check/change your boot order? (You have to hit F1 or F12 or something early in your boot process.) Edit: Or double check with another machine to see if the CD is bad, I guess.
Yes I do and I have already tried that. I put it in almost every order possible.
Which option should actually go first? Do you know the name?
I wouldn't think you'd have too many that say "CD-ROM" in them. I have this vague recollection that it usually says "ATAPI CD-ROM" or similar.
Also, if you have two physical CD drives, make sure you're using the right one -- generally the one on top. (Or if one's a burner and one isn't, the one that's not a burner.)
Only one drive and ATAPI CD-ROM is correct. Let me try once more.
No luck. What should the contents of the disk look like? Right now I just have an ISO image about 690mb. Do I need to download the kernel seperatly?
Have you checked the wiki, especially here? Seeing "just an ISO image" is not really a good thing (generally, not just here).
How the hell do you burn a cd wrong? Is there not just one way to do it?
No, a *.iso is an image of the ISO9660 filesystem ... in other words it's like having a disc in a file. You need to "extract" the file onto the CD, several burning tools can do it automatically -- I recommend ImgBurn (free)
You can save things on most live distros these days without needing to write to the hard drive. Most distros provide a "persistence" mode that uses a usb pen. Takes a little setting up, but once it's done it's rather seamless.
Ok I have got it running but cannot connect to the internet. I have no idea how to. ps. wlan isn't working I think I need the driver for linux on my laptop.
I tried Ubuntu after I saw near 100 unresolved WLAN questions in knoppix's forums. I can now get on the internet with ethernet but still missing drivers for WLAN.
Unfortunately, in the case of many WLAN chip producers do not publish specifications for their chips (so it's very hard to write a driver for those chips), and the company that makes the chip does not produce Linux drivers. There is a "Windows compatible" driver shim - this means you can use a well-behaved Windows driver in Linux. But I'm not clear on all the details of it.Quote:

For WLAN? matsp wasn't speaking in just the case of Ubuntu but Linux in general.
Wow that really sucks
Yes, but make sure you tell the chip manufacturers, not the Linux developers - it's the formers fault, not the latter. It's hard work to write drivers for a chip you KNOW how it works - it's near impossible to do for a chip where you don't have any instructions on how the chip actually works.Quote:

So there may be some 3-400 different values that need to be in the correct state at any given time. Obviously, figuring out what 300 odd registers do without a manual is like trying to solve a jigsaw puzzle with hundreds of pieces with no pattern to identify which goes where.
Most of them just need to be set up the once (to match the OS's view of things with the chips view of the world, and to match up with the actual hardware design), but some need to be reprogrammed when:
- a data packet has been received.
- a data packet has been sent.
- there is an error in receiving data.
- it didn't work to send the data.
- many other more or less common situations.
Wireless chips are further complicated by having a radio and encryption units that also have a few registers each.
There is some useful (at least I think so - I have never actually set up a WLAN chip on Linux) info here:

Of course I understand it's the chip manufacturers and not Linux's fault. I am just going to dual boot with windows whenever I need WLAN. Also, what is the latter? Iv'e heard the term a few times and now im really curious.
Former and latter are references to the first and last of something mentioned before. For example (sentence made up as I go along ...):
C is a programming language, so is C++. The former (meaning C) has no direct support for object oirientation, where the latter (meaning C++) has classes to help in an object oriented design.

I have a number of Linux boxes that use wireless. I either use a wireless card with a native driver (anything Intel seems to work fine and if you need to buy one look for the edimax brand - that uses chipsets with good linux support) or use ndiswrapper with the windows driver.
Either way, you need to understand that things arent as easy to setup under linux as with windows (mainly due to poor support from hardware vendors) so you are going to have to spend time googling problems, reading tutorials and generally fiddling with stuff until it works.
