• This is an urgent case because I am no longer boot into any OS in my laptop now, I am using my phone to post the question.

  • I am using dual boot on my laptop- Ubuntu 14.04 LTS 64 bit- Windows 8 and Windows 7 32 bit (When I choose to boot this option it will open the Windows chosen )

  • The problem happens today, I can't boot into the Windows. I tried to use boot-repair from Ubuntu to fix this issue but it didn't work. So I tried with the option to upgrade the GRUB (I think it is the source of problem). I follow the step provided by boot-repair, everything going well except when finished it prompt an error about saving file, I didn't notice it and I still restarted it(it can't make the paste link either).

  • This is the paste link of last good configuration that I have: Paste Ubuntu

  • Currently, when I power on my laptop, it just exist black page, I managed to get in the grub-rescue command-line and get the error /boot/grub/i386-pc/normal.mod not found. I followed the instruction in this answer but it didn't work either:Stack Answer When I type ls command, this is the list of available partition:

File system is unknown

  • (hd0)
  • (hd1)
  • (hd1,msdos6)
  • (hd1,msdos7)

File system is ntfs

  • (hd0,msdos1)
  • (hd1,msdos5)
  • (hd1,msdos3)
  • (hd1,msdos2)
  • (hd1,msdos1)

I tried to search through every partitions to find the normal.mod but I couldn't find it:

ls (hd0,msdos1)/boot/grub/i386-pc/normal.mod

The command echo and search.files is not available for me now.

When I type the command set:


I hope I gave enough information, please tell me what I need to do.

P/s: Because I am using phone to post so any edit is very appreciated

Edit 1: Update 1:

I managed to escape the grub rescue to enter the normal grub, I found only grub_old not grub in (hd0,msdos1) and I tried to run normal.mod from here and it worked.

Now, I am trying to find the linux kernel image to boot from this but I couldn't find it elsewhere, should I make another Ubuntu 14.04 usb stick to let it find the iso file inside that usb?

  • Better to see link from last Boot-Repair. But your install is in sda6, so if your ls shows that as hd1, then your system is promoting flash drive to hd0 and you want to manually boot hd1,6. – oldfred Oct 21 '15 at 15:38

I found a quite simple solution, write out here for anyone who need it:

  • You should have a Ubuntu in your CD or in your USB stick, prepare it.
  • Try to boot into this Ubuntu through boot option(In my case, I pressed F2 when I powered on my laptop, it is usually, F8, F10 or F12)
  • It will load Ubuntu components and will ask you want to Try or Install, choose Try it because you want to fix, not install a new one.
  • When get inside, try to find where GRUB is, install a new one through some command like:

    sudo grub-install

If everything worked well, you can boot normally in next reboot.
