Grub.cfg not booting Grub prompt will


Hi

I had a bootable lfs system on sda3, I decided to create a boot partition sda1, I then copy all of sda3/boot to sda1.
I get an error invalid file name "/vmlinuz-3.7-lfs-7.2"

I have adjusted fstab as needed
Code:
      /dev/sda1  /boot  ext4   defaults 0   0
      /dev/sda2  /opt   ext4   defaults  0   0
      /dev/sda5  /      ext4   defaults  1    1
      /dev/sda2  swap   swap    pri=1
      /dev/sda6  /home/spiky/spiky ext4  defaults 0    0
      proc       /proc    proc  
      sysfs      /sys     sysfs
      devpts     /dev/pts   devpts
      tmpfs      /run      tmpfs
      devtmpfs   /dev     devtmpfs
proc etc is set as per lfs all correct.

grub.cfg
Code:
set root=(hd0,1)

menuentry   "Planet-spike" {
             linux /vmlinuz-3.7-lfs-7.2 root=sda5 ro
}
I,m only showing relevent parts in grub.cfg The rest is all there.

It wont boot from grub!!!

If I get grub prompt
grub> set root=(hd0,1)
grub> linux /vmlinuz-3.7-lfs-7.2 root=/dev/sda5
grub> boot

Even using the tab it finds the vmlinuz file ok

It boots ok!!!!!

Mount shows all partitions mounted in the correct places

Is the file named vmlinuz or vmlinux? Your post has both.

1 boot dir to the new partition

Hi

I have checked the grub.cfg the entry is vmlinuz-3.7-lfs-7.2

It was a typo.

For my next guess, try changing this...
Code:
set root=(hd0,1)

menuentry   "Planet-spike" {
             linux /vmlinuz-3.7-lfs-7.2 root=sda5 ro
}
...to this...
Code:
set root=(hd0,1)

menuentry   "Planet-spike" {
             linux /vmlinuz-3.7-lfs-7.2 root=/dev/sda5 ro
}

Thats what I have got stiil no luck I have also rebuilt kernel so as to put the 3 files into the new boot dir/partition

I have also checked that vmlinuz, System and config files are on the partition and not in /boot dir

Hi

I fixed problem by reinstalling grub.
Is this something that should be done? According to the section in grub you should copy all over.
