I tried to install Gentoo for the first time.
I created /dev/sda3 for /boot and /dev/sda4 for /.
I compiled the genkernel and generate the initramfs file successfully.
After installing grub, I reboot the machine. Then the machine boot in grub shell. I found this link, and followed the instruction step by step.
Firstly, I executed "root=(hd0,2)"
Then I executed "kernel=/kernel-genkernel.... root=/dev/sda4 ro"
Then I executed "initrd=/initramfs..."
Then I executed ”boot"
The kernel was boot then when mounting root, it reported an error "your real /dev is missing files required to boot"
What does it mean? What should I do in the next step? Thanks.
