When boot procedure stops-ways to solve the problem

[radioamateur69]

Hallo experts here in knoppix.net! The boot procedure is certainly not a trivial matter even in normal HDD-Installations either we use Windows or Linux and a detailed knowledge will only be found when meeting IT-specialists.

Nevertheless.In May 2011 I started my first HDD-Installation with Knoppix 6.4.3 .Unfortunately this Installation only worked in a correct way for a limited number of PC-starts and then began to stop booting after hardware recignition and started shutdown. Klaus 2008 in the German knoppixforum gave me the advice to watch the meniu.lst in /grub and even more important the Xorg.0.log in /var/log.

The activated driver "nouveau" reported no screens found and so to me it was clear,that the problem was the failing cooperation of graphiccard and knoppix driver. I started a complete new Installation with changed cheat codes at the start of the Live-DVD (xmodule=nv, nomodeset) and this improved HDD-Installation works stable till the present day.

But i still had a HDD-clone from the unstable HDD-Installation with unsuitable cheat codes. No one will wonder that this clone crashed some weeks ago, when the harddisk came into action. Of course one could secure the data from /home of this crash candidate and start a time consuming new HDD-Installation with the new proper set of cheat codes.

Now both HDDs were were installed with Knoppix 6.4.3 on the same PC with the same Live- DVD. I started reasoning that it might be possible to consider the well working HDD as a "data collection" and to copy a number of relevant data for booting into the crash candidate- I copied the menu.lst from HDD-well to HDD-bad with a Live-DVD.This can easuly be done but was not sufficient to make the HDD-bad work well again.

Even the complete exchange of /boot brought no successs.. Now my question:

1)Makes the whole procedure sense at all?

2)Which further data, like config-lsts and so on .are relevant in this case and are to be ex- changed.?

I remember that there are similar ways with repairing CDs or DVDs to repair lost system data or damaged system .dlls in the Windows-world. Now here with Knoppix ,experimental software as Klaus Knopper says , I thought it might by wortwhile to make some experimental effort to get more experience with troubleshooting in the always new and surprising Knoppix-world!

Grateful for hints of any kind or reports to solve similar problems
