OK, I tested this, and again, it seemes to work (setup reports no errors) but in fact the system was still unbootable. I decided to kill the MBR completely: dd if=/dev/zero of=/dev/sda bs=446 count=1 Now, it is really gone ;) I wrote an image with the MBR and the partition-table to my harddisk: dd if=/dev/sda of=MBR_clean.img bs=512 count=1 I have tried to write the MBR again via grub-install and wrote the new MBR to my harddisk: dd if=/dev/sda of=MBR_new.img OK, now I compared both images: diff MBR_clean.img MVR_new.img diff told me, that both files differ. Fine, my assumption, that I have a problem to write the MBR was wrong ;( I started again with digging into the BIOS options: I have found an option "Prevent booting from IDE HDD" enabled. As Linux uses an SCSI-devicefile (/dev/sda*) I thought that this option has no effect. (This was the second wron assumption ;() After diabling this option the system starts without a bootfloppy. Sorry for that ;) Thanks for all the help, Andre -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
