We can get the operating system to boot 'by hand' in AHCI mode by doing the following:
The system was reinstalled using the AHCI SATA option in BIOS. After installation, we sre dropped to a 'grub rescue' prompt when the OS tries to boot. Typing the 'set' command at the grub prompt reveals that the prefix is set correctly. prefix=(hd0,msdos1)/boot/grub >From there, the kernel and initrd can be loaded manually, the root device set, and the OS will boot. grub> linux /vmlinuz root=/dev/sda1 ro grub> initrd /initrd.img grub> boot Those steps will get the operating system booted in AHCI mode. None of this is required if the SATA mode in the BIOS is changed to ATA or RaidOn. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/741799 Title: OS fails to boot certain SATA drives in AHCI mode. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
