After using the cooking iso I downloaded today (because rootfs.gz was not detected on the boot cd) and mounting it on /media/cdrom, I had troubles with a reboot, grub had no entries but only a grub> prompt. so I tried reinstalling slitaz and looked at the installation logfile and it had the following

Which makes me think that slitaz borked my grub installation. I have not been able to restore it using supergrub yet. I am downloading an ubuntu iso with the hope that it can restore grub properly.
