I have a running iso on my HDD and if I use this it works....
I am running linux and I can test iso before burning to cd with a "mount -o loop" of the iso-image, so testing is very easy.
If I build a new iso from my files (it doesn't matter if I use the files located on the running cd or my own customized ones) booting ends with a black screen showing
"Error booting from CD/DVD drive.
Press any key to reboot..."
on top of the screen, and
a line with white bars and a few dots on the bottom, followed by "804003F9"
I use the following mkisofs-command:
mkisofs -N -J -r -o /home/andreas/ubcd.iso -b boot/loader.bin -no-emul-boot -boot-load-size 4 -joliet-long -allow-multidot -allow-leading-dots -iso-level 2 .
I've tried
mkisofs -N -J -r -o /home/andreas/ubcd.iso -b boot/loader.bin -no-emul-boot -boot-load-size 4 .
too, doesn't work at all. When I open the CD in working OS, al files are readable on CD so the problem must be at bootloader or so.
I cant understand because of I already have had build isos some months ago - without any problems. Has anyone any idea?? I don't hope I get stupid
