Q: Repairing Grub - Separate Partition - Dual Boot Windows I am attempting to repair grub on separate /boot partition without removing Windows Boot Loader.


*

*I installed Ubuntu 12.04 after Windows 8 on 250GB SSD drive.

*Grub installation failed during Ubuntu Install on separate /boot partition (I chose to skip grub install after this happened)

*However, Grub does seem to be installed on that separate /boot partition. However, grub command line is loaded when I boot to it. I don't think there are any OS entries.

*I created a entry in Windows Boot Loader directly to Ubuntu OS partition, but it does same thing: grub command line.

*I am following instructions here with Live USB:

*

*https://help.ubuntu.com/community/Grub2/Installing#Fixing_a_Broken_System
I'm worried that this command will overwrite MBR and Windows Boot Loader: 

sudo grub-install /dev/sda

I tried this, but it tells me that installing grub to a partition is not recommended: 

sudo grub-install /dev/sda3



*

*Do I even need to do an install? 

*Do I just need to update config with OS entries? 

*I've seen chroot mentioned.


Here is my fdisk -ls:
Device    Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048      718847      358400    7  HPFS/NTFS/exFAT

/dev/sda6       480585728   488396799     3905536   82  Linux swap / Solaris

Any help is much appreciated!

A: I ended up just re-installing Ubuntu and did not include a separate /boot partition this time.  Grub installed to my Ubuntu partition and and Windows boots to that.

A: Did you try boot-repair (installation guide) program. In that program, select advanced options. It will help you you install grub manually where ever you want and also restore MBR. So I think you should install grub to sda and will be able to boot all OS from the GRUB menu. 

A: Dude, the dude here https://wiki.manjaro.org/index.php/Restore_the_GRUB_Bootloader
Describers how to do what you want.  I too installed Ubuntu with /boot.
