[SOLVED] Can't boot after make image

I have a physical machine that work like my server yesterday i use clonezilla to backup the disk to make a virtual machine with it (convert the physical machine in virtual).
Everything worked ok until i try to boot the machine in virtualbox, now i have this error:

:: Loading root filesystem module...
Attempting to create root device '/dev/sda3'
ERROR: Failed to parse block device name for '/dev/sda3'
unknown
ERROR: root fs cannot be detected. Try using the rootfstype= kernel parameter.
Wating for devices to settle...done.

Root device '/dev/sda3' doesn't exist, attempting to create it
ERROR: Failed to parse block device name for '/dev/sda3'
ERROR: Unable to create/detect root device '/dev/sda3'
Dropping to a recovery shell... type 'exit' to reboot
NOTE: klibc contains no 'ls' binary, use 'echo *' instead

If the device '/dev/sda3' gets created while you are here,
try adding 'rootdelay≃8' or higher to the kernel command-line
ramfs$

I can boot fallback.

This is my fstab:

# 
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0


/dev/cdrom /media/cdrom   auto    ro,user,noauto,unhide   0      0
/dev/dvd /media/dvd   auto    ro,user,noauto,unhide   0      0
/dev/sda1 swap swap defaults 0 0
/dev/sda2 /home ext3 defaults 0 1

And this is my menu.lst:

# (0) Arch Linux
title  Arch Linux
root   (hd0,2)
kernel /boot/vmlinuz26 root=/dev/sda3 ro 5 vga=795
initrd /boot/kernel26.img

# (1) Arch Linux
title  Arch Linux
root   (hd0,2)
kernel /boot/vmlinuz26 root=/dev/sda3 ro 3
initrd /boot/kernel26.img

# (2) Arch Linux
title  Arch Linux Fallback
root   (hd0,2)
kernel /boot/vmlinuz26 root=/dev/sda3 ro
initrd /boot/kernel26-fallback.img

Can you help me ?

Re: [SOLVED] Can't boot after make image

Thanks for posting the appropriate config files.

Your fstab has a swap partition and a /home partition, but no root partition! Certainly not good.

Something probably went wrong in the imaging process. It seems like your grub setup seems to think there should be a sda3 root partition there.

You can boot a livecd and run fdisk -l to see what partitions you have, but it looks like the root partition missed being copied properly.

Sorry my mistake, when i paste it:
The right one is :

# 
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0


/dev/cdrom /media/cdrom   auto    ro,user,noauto,unhide   0      0
/dev/dvd /media/dvd   auto    ro,user,noauto,unhide   0      0
/dev/sda1 swap swap defaults 0 0
/dev/sda2 /home ext3 defaults 0 1
/dev/sda3 / ext3 defaults 0 1
