 |
|
I installed Gentoo on a old harddisk.
Then I copied it to a new larger disk.
| Code: | | cp -ax / /new-drive |
Because it is a old computer with a old BIOS (Compaq 300 MHz...) it can't boot with the new disk.
When I booted it with a LiveCD and chrooted to the disk, the /dev directory was empty.
Is there anything I can do besides reinstalling?

gul,
cp does not copy the parts of grub installed outside the filesystems.
You must reinstall Grub on the new drive.
/dev should be almost empty, its managed dynamically.
No need to reinstall, this isn't Windows.

The problem is that I can't install grub on the new drive
| Code: | | grub-install --root-directory=/boot /dev/hda |
dosen't work because /dev is empty |

When using devfs or udev you /dev of your root partition is hiden by the mounted devfs or in memory filesystem.
when coping the root partition it helps to bind it to /mnt/root/ for example
| Code: |
mount -o bind / /mnt/root
|
should do it. you might want to remount it ro before that
| Code: |
mount -o remount,ro /

well the | Code: | | mount -o remount,ro / |
didn't work (device was busy) but | Code: | | mount -o bind / /mnt/root |
did the trick
now I can boot using a 160 GB harddisk in a old compaq computer (Pentium II 300 MHz) |

That's useful.
Can you detail what you did? What does mount show now?
Thx
