Installation issues - Sata Raid unable to boot (via grub)

Post by leo_mancini » Sat Apr 28, 2012 15:50

Hi all,

I have an old computer with which I am attempting to install Sabayon 8 onto. I have ran a live cd (KDE version) and ran an installation via the 'text installation' (as I had issues logging running the gui installation). This installed successfully, though I've had an issue with GRUB.

So according to the installation - the boot loader had installed correctly, but this in fact was not the case.

I was required to chroot into the hardware firstly by mounting my LVM partitions using the ... _Mount_LVM instructions... Then using the ... tore_Grub2 I successfully managed to chroot into the system, and had successfully installed grub2 onto the master boot record (MBR) of the RAID Sata hard drive. Please note though the step (grub-mkconfig -o /boot/grub/grub.cfg) did not work (I'm sorry though I can't recall the error message).

Now each time that I boot up the computer, I am met with a grub command prompt. This is where my lack of knowledge really kicks in :(

I have attempted to type in

Code: Select all

set root='(hd0,msdos1)'                 
linux /kernel-genkernel-x86_64-3.2.0-sabayon
initrd /initramfs-genkernel-x86_64-3.2.0
This appears to start the boot process... though eventually it reaches a point where it states 'unable to find root device'.
I don't know what I can do to get past this point. I am offerred an opportunity to get into a shell, but I've got no idea. I've had a look at the dev folder and tried exiting the shell and typing /dev/sda, though this has not been successful (as I'm assuming it is looking for the lvm volume name instead.

so at this stage, I'm guessing, I'll either need to
1. re-install grub OR
2. issue the correct command in the grub command prompt so that I can boot the system, then proceed to create a grug.cfg file.

any help would be greatly appreciated.

Thank you.

What does your /etc/fstab look like? Did you use a separate /boot partition?
