  • What "boot partition" are you referring to? A separate partition for /boot is never a compulsory thing. – Tom Yan Feb 18 '16 at 14:58
  • Is the "hangs here" your actual question/problem? – Tom Yan Feb 18 '16 at 14:59

What is your question? GRUB can boot from MBR area ,and has modules to access files in ext4 partitions. Only in GPT there is a need for a BIOS boot partition or EFI partition

As for the hang,can you provide

  • mount info ?
  • df free space ?
  • I have updated the question – Edik Mkoyan Feb 18 '16 at 16:17
  • how long did you try to wait for the apt-get install command completion ? have you tried looking at iostat IO utilization? is this a virtual machine? – Sidias-Korrado Feb 18 '16 at 16:21

I don't see your issue.

Your partition with the boot flag is the following :

>    Device Boot      Start         End      Blocks   Id  System
> /dev/sda1   *        2048   100663295    50330624   83  Linux

It refers at your "/" ext4 partition.
