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
File system is ntfs
I tried to search through every partitions to find the normal.mod but I couldn't find it:
The command echo and search.files is not available for me now.
When I type the command set:
cmdpath=(hd0) prefix=(hd0,msdos1)/boot/grub root=hd0,msdos1
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?
