[SOLVED] grub-install /dev/sdX on a Virtualbox Appliance

Habitual · 07-24-2014, 12:36 PM

I'm at 8.4. Using GRUB to Set Up the Boot Process and I have to ask for guidance.

The appliance is slackware 14 on 32 bit architecture.
sda is slackware
sdb is lfs (dev)

My goal is to remove the slackware.vdi from the appliance.

I think I should use

Code:

grub-install /dev/sdb

inside my lfs environment since sda1 would be removed soon'ish?

But what about /etc/fstab?
It too would need modification from

Code:

/dev/sdb1      /            ext4     defaults            1     1
/dev/sdb2      swap         swap     pri=1               0     0

to

Code:

/dev/sda1      /            ext4     defaults            1     1
/dev/sda2      swap         swap     pri=1               0     0

and my grub.cfg should then be:

Code:

set root=(hd1,2)
> 
> menuentry "GNU/Linux, Linux 3.15.6-lfs-SVN-20140723" {
>         linux   /boot/vmlinuz-3.15.6-lfs-SVN-20140723 root=/dev/sdb1 ro
> }
> EOF

This isn't really a Question question, just me sounding it out.

Tips, ridicule, encouragement, beer gladly welcomed.

Seems to have worked!

Code:

/etc/fstab:/dev/sda1      /            ext4     defaults            1     1
/etc/fstab:/dev/sda2      swap         swap     pri=1               0     0
/boot/grub/grub.cfg:set root=(hd0,msdos1)
/boot/grub/grub.cfg:        linux   /boot/vmlinuz-3.15.6-lfs-SVN-20140723 root=/dev/sda1 ro

My first lfs system and it only took a week!
