hi I will try to use linux on my laptop but it is really difficult.

I have already linux on it in a linux partition using a separate swap partition. but the used distribution limites the user so much that it is really absolutely not plaisant to work with it (you can't login as root to make changes in your /etc or try to install new programs and more. to change the content of this debian like distribution, the easiest way I did find to change settings in /etc is to use a live CD, mount the partition of the harddisk and make the changes and restart. it is absolutely nonsens, and it is not a practicable way to install new programs etc. i am sad and really sorry because this distribution is really good but this limitation is not acceptable)

so I did decide to install now an other distribution hopping this distribution has not the same limitation, slackware 11.0.

here, I have a new and completely different problem:

mit CD-writer will not read the iso-cd burned with it (on the PC of my wife, the same CD starts! the cd is good). i suppose that i have to start the PC with a floppy or a live-distribution like puppy-linux and after that to start the installation script of the first iso-cd from slackware

what is to do in the one or in second case to make one of both systems really operable without such extrem limitations or installations difficulties?

You could install from an USB device too (floppy is possible too, but I guess USB stick would be easier since you have to handle only one device).
At http://www.slackware.com/~alien/slackboot/usb/ you will find the USB installer that AlienBob created and which will be included in the upcoming Slackware release. I never tried it, but I'm quite sure it will work. If you have any problem with that a question in the Slackware forum should be fine.

Steps you need to make first: Start your already running Linux, copy the "slackware" folder somewhere where you don't need to reformat. Then when booting from your USB stick you can choose to take the packages from a mounted partition. Change to console number 2 (Alt+F2), log in as root, make for example the folder /here-they-are and mount the partition with the packages there. Switch back to console 1 and type in the path to the package folder (for example "/here-they-are/something/in/between/slackware" or whereever). Floppy install works the same way but you have to create some (three???) floppies. They are on the installation CD in /bootdisks and /rootdisks (sorry, never used them, so I can not give further tips here).
