Same problem with ASUS P5B series. Installed on PATA HDD (Primary) using PATA DVD/CD-RW (Secondary). Installs without a problem, but "Grub error 21" upon reboot.
Rebooting using Live CD, cannot find HDD in /media directory. Sysguard shows that both HDD and DVD/CD-RW are detected by system under the Jmicron controller, but not visible in /media. Will try the BIOS upgrade shortly and report back. -- JMicron controllers not recognised by Grub? https://launchpad.net/bugs/64574 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
