Ubuntu – Grub2 installation fails for Ubuntu 16.04 LTS

16.04dual-bootgrub2mountsystem-installation

I have been trying to install Ubuntu 16.04 on my Lenovo Ideapad500-15isk alongside windows 7 using a usb live disc.

I have kept 8200MB of swap space

and 20482MB of mount point /

and around 390 GB of space with mount point /home.

I downloaded the 64 bit ISO file from http://releases.ubuntu.com/16.04/ and used rufus as well as the Startup disc creator in Ubuntu to create the live disc.

But the Ubuntu Installation fails to load grub 2 every time. What could have possibly gone wrong?

Also since I'm already using a 64bit windowsi doubt that is the problem.

Best Answer

Recent Windows versions (most likely starting with Windows 7) create a hidden boot partition by default and Linux installers seem not to be able to handle it correctly.

Is this your case?

In Windows, run diskmgmt.msc. Your primary disk starts with a System Reserved partition of size 100–200 MB. Click on the disk’s grey field in the left and open Properties. On the Volumes page, the Partition style is Master Boot Record (MBR).

Solution

  1. Get a spare drive and backup your current drive setup with Clonezilla or similar software. It can save your system if you do a mistake in the following procedure!

  2. Make the partition visible to Windows, move its data to C: and update settings of the boot manager. Use this detailed guide: https://www.terabyteunlimited.com/kb/article.php?id=409

  3. Once Windows boot fine without their hidden partition, you can install Linux to make a dual-boot setup.
