The kernel is missing the driver for your disk device. 801 is /dev/sda1: # ls -l /dev/sda1 brw-rw---- 1 root disk 8, 1 Aug 4 2013 /dev/sda1 WD800BEVS-08 is a 5400rpm 2.5inch sata disk. Go into the bios and set up sata to be AHCI. You have no initrd/initramfs so: "SCSI disk support" "Serial ATA and Parallel ATA drivers (libata)" "AHCI SATA support" and possilbe also "Platform AHCI SATA support" driver must be compiled in in the kernel. You can check that by doing something like: # grep BLK_DEV_SD= /boot/config.production CONFIG_BLK_DEV_SD=y # grep CONFIG_SATA_AHCI /boot/config.production CONFIG_SATA_AHCI=y CONFIG_SATA_AHCI_PLATFORM=y You must also compile in the filesystem used for / (perhaps it is ext4). # grep CONFIG_EXT4_FS= /boot/config.production CONFIG_EXT4_FS=y Every time you change the kernel you have to rerun lilo.
