Once you finish with scanning the WinXP for viruses then then definitions are |
16 |
no longer needed. If you scan it again in the future using KRD, then these |
17 |
will be downloaded afresh. |

The KRD image was created for a particular purpose. It is not meant to be a |
31 |
permanent Linux installation with the ability to update itself and any |
32 |
applications it may include. |

That's as intended by its creators. |

Yes, this is correct. A live CD/USB ISO image is of course read only. |

You can't change the ISO as is. You have to follow the many examples in |
54 |
Google for unpacking it, making your changes and then re-packaging a new ISO |
55 |
image which includes your changes. |

From what I know there are problems trying to use a design intended to be used |
64 |
as a LiveCD/USB in place of a permanent installation. The two are not the |
65 |
same in design or execution. |

That's why there are a myriad tools to run back ups of your critical data. |

Running an OS from a USB is going to be slow. Even on a fast USB (unless |
87 |
we're talking about USB3 which is faster). I suggest you consider defragging |
88 |
WinXP, shrinking its partition and creating new partitions to install Linux |
89 |
on. |

There is the alternative of installing VirtualBox on your WinXP and then |
96 |
installing Linux in that. In this way you do not need to re-partition your |
97 |
hard drive and you can always save the VM image to a USB for backup purposes. |

PS. Have a look in the Knoppix forums and FAQs which explain with a LiveCD is |
100 |
not designed to be used as a permanent installation. |
