Hello
I have a SLES12SP5 VM in VMware ESXi 6.5 that I ran zypper patch on and then rebooted.
Now it’s stuck on “GRUB” in the upper left corner of the screen when booting.
I can boot from a SLES DVD and then select Boot Linux System and start the OS that way.
The information I found about repairing GRUB is focused on SLES10 or 11.
Any tips on how to fix this?
Thanks
Hi
Have you tried making a change in YaST bootloader so it rebuilds grub or from the cli;
grub2-mkconfig -o /boot/grub2/grub.cfg
Do you get errors? Does the GRUB_CMDLINE_LINUX_DEFAULT look ok in /etc/default/grub
Is /boot a separate partition?
See:

for grub repair instructions.
Hello,
I booted from the ISO and did an “upgrade” over the current installation and that fixed it 
Thanks for the tips.
