Hey, where's the fire?

Making no bootfloppy is kinda like "your fault", but...
...I didn't make on either, and...
...When you have just installed Knoppix there is no real danger in not being able to boot into it. You can always reinstall, or do what you did, boot the Windows boot disk and "fdisk /mbr".

The hdinstaller *should* indeed give you the choice between LILO and Grub. It would be even better if the choise was more or less automated, if either one will not work on your particular config. There should have been documentation on adding Linux to the XP boot menu, etc. But...

...You didn't pay a cent for it. (well...)

So if you would want it added, you can hire Klaus Knopper. Or hope he (or someone who helps him) adds it all by himself

Trying to be friendly would shurely help.
