Hi Firstly I'd like to say am a work in progress in windows and a beginner in Linux. Ok now then let me get to my issue, basically am stuck on grub rescue after a normal shut down in on windows on a dual boot system. Here's the events leading to this problem. BTW am on windows 10.
I have a 1TB HDD on a Toshiba C660, my HDD partitions were as follows all in numeric order according to minitool partition (and this is if I remember correctly): 1.Windows system reserve 100GB 2.Windows installation C:\ 160GB 3.Backup F:\ 600GB(made by me for storing data) 4.Unallocated space (140GB). This was primarily how my HDD was after I reset it with a complete clean leaving only 130GB of data in the Backup partition. I left the remaining 140GB unallocated because I was planning to install Ubuntu Linux the way I did alongside windows 8 previously, as it turned out windows 10 had an issue of not being detected by the live CD installation of ubuntu. So I searched the web for some fixes and I came across a guide that explained how to manually set up portions to install it alongside by making the "/ 32Gb" , /home 100Gb and "swap 8Gb" partitions all went well with the system going through grub on each startup, since I had the backup part I on in mind as a sort of portal to shared files for both systems I was punched in the face the face by the unmountable partition error which usually going through windows and shutting down fixed but this time it wasn't working, I even put the laptop on shutdown ,disconnected the charger and removed the battery for 10 minutes. Seeing as I couldn't use the backup partition as a shared one I had the problem of having no space for the data I wanted to have on the Linux side so I went back in windows and used minitool part I on to resize the backup drive leaving it at 380+GB and create a ext4 200Gb leaving an unallocated 15gb, the partition went successful and since the Linux portions weren't visible from windows I thought if maybe I did a shutdown once more and when I got to the Linux side it would allow me to see and copy the data I needed for once to the new partition. And lo and behold on startup I got a black screen with an error saying.
Error: file '/boot/grub/i386-pc/normal.mod' not found. Entering rescue mode... grub rescue>
After the making of Linux and creating of a second backup partition, the partition list was as follows (continuing from original layout). 4.Linux Backup 200Gb 5.Unallocated space 15Gb 6. / root 32Gb 7. /home 100Gb 8.Swap 8Gb. From when I only installed Ubuntu it was 123 and 678. The was another hidden partition on the windows side but it was hidden and I don't remember were it was between the other partitions.
