Windows 10: Ubuntu Dual Boot

I am using the non-metro Windows 10 boot loader to manage a dual boot setup (legacy BIOS) with Ubuntu. Generally, everything works fine. However, sometimes when I perform an update in Ubuntu, grub overwrites the Windows MBR. Then I have to use EasyBCD to restore the Windows boot loader.

Here's the partition info on my primary drive:

Code: sudo fdisk -l Disk /dev/sda: 120.0 GB, 120034123776 bytes 60 heads, 12 sectors/track, 325613 cylinders, total 234441648 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xea0264f2 Device Boot Start End Blocks Id System /dev/sda1 * 2048 1026046 511999+ 7 HPFS/NTFS/exFAT /dev/sda2 1026048 171522991 85248472 7 HPFS/NTFS/exFAT /dev/sda3 171524094 234440703 31458305 5 Extended Partition 3 does not start on physical sector boundary. /dev/sda5 171524096 230117845 29296875 83 Linux /dev/sda6 230119424 234440703 2160640 82 Linux swap / Solaris ...[/quote] I have tried using grub-install --force /dev/sda5 to move grub off the MBR, but receive a warning stating ext2 partitions cannot be embedded. This is weird since I have confirmed that the partition is in fact ext4.

How do I prevent grub overwriting the MBR?

WILL THE UPDATE AFFECT THE DUAL BOOT......CURRENTLY USING 8.1 PRO AND UBUNTU.....

It likely will affect your Ubuntu installation. When dual booting Linux and Windows, it is best that Windows is installed first.

If you do upgrade to Windows 10, do this after.

Run Boot-Repair to reinstall your GRUB.

My Acer Aspire E 15 upload Windows 10 nicely from Dual Boot. I have also installed Ubuntu 14.04.3 LTS. Dual Boot is unable to upload Ubuntu error message 0xc00000tb

I am never a fan of using dual boot. I have Windows 10 installed on a separate GPT SSD and Linux installed in MBR SSD and run them separately using Boot Menu so they are completely independent from each other.

However. This Video will show you how to setup the Grub Boot loader on its own partiiton so that they are independent from each other.

This demonstrates exactly what I want. However, I did not select the grub location during installation. I need to change the grub location after installation. So far, I cannot find a way to accomplish that task. Does this mean I would have to reinstall Ubuntu?

 

IMHO, It would be better to re-install, it should not take long any way.
Good luck !!!

 

Unfortunately, this is not a fresh install. I have considerable effort invested in post-install configuration. So I'm reluctant to reinstall.

I did find some references to using sudo dpkg-reconfigure grub-pc which allows me to deselect /dev/sda and select /dev/sda5. The next time grub is updated, I'll know if this fixed the problem.

 

As long as you have it setup as shown in #3. You should be OK.
