I'm new to Elementary.
Initially I had Ubuntu 14.04 LTS along with Windows 10. I wanted to remove Ubuntu and install Elementary OS. So, my friend ran
sudo rm -rf / --no-preserve-root and then it started removing a lot of things. Suddenly it stopped showing progress (or that is what I felt), so I turned off the computer. When I tried booting it, it started checking for hardware malfunctions and it said "No hardware malfunctions, OS image might have been corrupted or USB boot is not setup in BIOS."(not exactly sure of the error message, it was somewhat like this). So, I tried to go the BIOS setup menu. Here, I restored the setting hoping this would allow me to boot to Windows. This attempt was unsuccessful.
Then I tried installing Elementary OS using a bootable USB. I was able to install on the partition containing Ubuntu by formatting it. After successful installation I rebooted and was directly led to Elementary (without any grub page). On mounting Windows partition I found all my files were intact (as far as my knowledge goes).
Then I noticed that line 7 in
GRUB_HIDDEN_TIMEOUT=0 rather than
#GRUB_HIDDEN_TIMEOUT=0 (the one in my friends file). After commenting this line, updating grub and rebooting, the grub menus was back although there was no option to boot to Windows. The link to the image of this menus is has been posted as a comment below (since I can't post more than two links in the question due to lack of reputation)
Now, we checked the
/boot/grub/grub.cfg. Here, there was a difference in line 270 onwards when compared to my friends file. These are shown below:
Now, as you can see, some lines are missing in my case. Also, line 254 in my friend's file has different numbers when compared to the corresponding line in my file, I decided not to copy the missing lines or change the file (as it also said in the beginning not to edit the file).
On googling, all the situations had the problem of not being able to boot into Linux rather than the other way round.
So, I'm posting this question here: Can you suggest any way to add the Windows boot loader option in the grub menus?
Thanks in advance.
