I was trying to install Ubuntu 18.04 LTS alongside Windows 10 when it crashed halfway during the installation saying that it was unable to install the grub. After closing it and opening Windows 10, I found that a new partition had been created. Now what should I do to that partition and how should I install it again?


This is a little bit of a shot in the dark but I can only think of 3 reasons why grub wouldn't install (in the order I think would be mostly likely):

  1. The BIOS is protecting the MBR (master boot record) from being written
  2. The boot section of the hard drive is corrupted (less likely since Windows boots)
  3. grub on the installation media is corrupted

If you try installing again, are you able to install grub on the new partition instead of the MBR? (you will see an option for that at the end of the installation process). If so, then that eliminates #2 and #3 and points to #1.

  • When i am installing, should i go for the "boot along side windows 10" option or the "something else" option? Dec 22 '18 at 13:02
  • "boot along side window 10" if you want to be able to multiboot.

  • When will I be able to choose the disk parition? Dec 22 '18 at 13:06
  • I think it's the last prompt, just after the installation but before the reboot.
