today I have tried to fix this machine via the 15.6rc media rescue bootentry, mounting / and /boot and adding sys dev proc and run and then chroot into the system I have tried to look into grub , grub_installdevice and those parts and it looks fine, the disk UUID and names and partitions etc all exist and make sense and are correct. inside chroot: firing up the yast on the commandline and making it re-install the boot setting rewrite MBR or bootstuff into the whole disk and the partition of /boot and all finishes without erros being shown from inside yast. the system doesnt boot after this either. rescue once again and then mkinitrd installs kind of multiple big blocks worth of kernel stuff (with log output) and at the end with the 6.4.0 kernel entry it seems to fail at the dracut step and prints the error to the screen, and this error seems to be in the log files I have provided as an attachment earlier. -------------- zypp-history-log-0000.txt-# dracut[E]: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.7LMEwP/initramfs -N ^i2o_scsi$ --kerneldir /lib/modules/5.14.21-150500.55.49-default/ -m pata_atiixp ahci ata_generic sata_nv pata_amd fan amd74xx ide_pci_generic reiserfs edd zypp-history-log-0000.txt:# dracut[F]: installkernel failed in module suse-initrd zypp-history-log-0000.txt-# warning: %postun(kernel-default-extra-5.14.21-150500.55.49.1.x86_64) scriptlet failed, exit status 1 --------------- it seems that I can not make this hosed system to boot any more even after repair attempts with the 6.4.x kernel entry thanks.
