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:
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/sda2 718848 439648255 219464704 7 HPFS/NTFS/exFAT /dev/sda3 439648256 440135679 243712 83 Linux /dev/sda4 440137726 488396799 24129537 5 Extended /dev/sda5 440137728 480583679 20222976 83 Linux /dev/sda6 480585728 488396799 3905536 82 Linux swap / Solaris
Any help is much appreciated!
