View Full Version : [ubuntu] Dual Boot - No GRUB

October 9th, 2012, 03:20 PM
I have Windows 7 installed in a primary partition and wanted to install Ubuntu 12.10 in a new partition.
Even before starting the installation, I knew that I might run into a few problems because the partition I was installing Ubuntu on was displayed before the W7 partition in the Disk Manager of Windows.
After the install, I didn't get a GRUB menu on reboot but was directly booted into W7.
A used a LiveUSB to boot into Ubuntu (Try Ubuntu) and ran the BootRepair software with the recommended settings. It showed an unsuccessful, the result (http://paste.ubuntu.com/1269285/).
Now, I'm still directly booting to W7, but have access to the LiveUSB. Can someone guide me on how to have GRUB displayed on boot?

Ran BootRepair again with Advanced settings...the new results (http://paste.ubuntu.com/1269349/)

Reinstall the GRUB of sda1 into the MBR of sda /usr/sbin/grub-bios-setup: warning: this LDM has no Embedding Partition; embedding won't be possible. /usr/sbin/grub-bios-setup: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged.. /usr/sbin/grub-bios-setup: error: will not proceed with blocklists. grub-install --recheck /dev/sda: exit code of grub-install /dev/sda:1 Embedding-error-in-sda detected. You may want to retry after activating the [Separate /boot partition:] option.

I am not very sure , but I think Grub is incapable to read LDM partitions.

Also , this bug exits : https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1053793

not confirmed yet , but maybe has a relation to your problem.

What I suggest ?
To install syslinux instead of Grub. (until Grub BE capable to manage such partitions).

Should I follow these instructions to install syslinux ?

Boot-Repair will install syslinux if you just want to boot Windows.

But you installed grub2's boot loader to the MBR of sda1, a partition. You need to install grub2's boot loader to sda the drive. Boot Repair will do that.
