I installed ubuntu on a PC "server" for offline development purposes but im having slow boot ups.

When i press the power button the system goes straight to the CRUB menu for about 2 seconds. But then goes to a black screen with fast moving text. This process usually takes about 5 to 10 mins.

Is there any solution to fix this problem or will i have to re-install everything ?

This is a clean install, With noting else installed yet.

    did you installed Ubuntu Desktop or Ubuntu Server? Also paste the output of systemd-analyze critical-chain. – Manish Kumar Bisht Jan 10 '17 at 14:41

It sounds like a kernel panic (hard crash). It can come from a hardware failure... like a defective hard disk, bad RAM, or from corruption of a software component.

The first thing is to perform a file system check on your Ubuntu disk. Hopefully you can do this on the server version of Ubuntu...

  • boot to the GRUB menu
  • as soon as you see the GRUB menu, and before it crashes, hit the down arrow key (you may not be able to get this far)
  • choose Advanced Options
  • choose Recovery mode
  • choose Root access
  • at the # prompt, type sudo fsck -f /
  • you can ignore errors about the time/date/superblock
  • repeat the fsck command if there were other errors
  • type reboot

The second thing to do is to use the SMART internal disk monitoring tools to see if it detects a pending hard disk failure...

  • create a Ubuntu Live DVD/USB desktop version
  • boot to the Ubuntu Live DVD/USB
  • start the Disks application from the Unity dash
  • select the hard disk in the left pane
  • click on the "hamburger" icon in the top-right of the Disks window
  • select SMART Data & Tests
  • view the data, and run the tests
