Installing Grub on Disk Image
 
Hello
I was following the LFS (Linux From Scratch) Project 6.7,and i was able to finish up with a booting kernel.i did most of the compilation on my old Toshiba laptop.my problem resides is that i got tired of working on this very old pc , So i did a disk dump of the partition on which LFS is built on in order to use it on my newer laptop and run it using qemu .On my older system i used grub of the host system in order to load the kernel.My question is : can i install grub on the new disk image ? i tried loading it as a second hard drive with Ubuntu live-cd from qemu but it didn't work .Any suggestions ? i'm running Ubuntu 10.10 for x86_64 m kernel version :2.6.35-25-generic
Thank you

If you can you boot the QEmu guest with a Live or installer CD or minimal floppy image you should be able to install GRUB. Definitely the easiest way. So maybe start by explaining the "didn't work" part?

The didn't work part
 
Thank you for your reply
This how i launched qemu:
Code:

kvm -hda ./Desktop/disk_0.img -cdrom ubuntu-10.04.1-desktop-i386.iso  -boot d -m 256
When i run
Code:

sudo fdisk -l
inside the virtual Ubuntu
I get the following output:

Code:

Disk /dev/sda :516 MB ,516096000 bytes
4 heads , 32 sectors/track , 7875 cylinders
Units = cylinders of 128 * 512 = 65536 bytes
Sector size (logical/physical): 513 bytes / 512 bytes
I/O size (minimum/optimum): 512 bytes /512 bytes
Disk identifier: 0x00c545c
  DEvice Boot      Start    End    Blocks  Id System
/dev/sda1              1      7875    503968  83  Linux

When i run :
Code:

sudo grub-install /dev/sda1
I get the Following error :
/usr/sbin/grub/grub-probe : error : cannot find a device for /boot/grub (is /dev mounted?)
No path or device is specified
Auto Detection of file system module failed

Even when i try with --modules=ext2 it get :
you attempted a cross disk install , but the file system containing /boot/grub does not support UUIDS .

any ideas ?
