My laptop - Dell Inspiron 5558, RAM: 8GB, Processor: Intel Core i5, graphics: 4GB

I successfully installed Ubuntu system on my laptop from bootable DVD yesterday.
Until that time no problems or errors were found. Then I removed my DVD from laptop and restarted my laptop, but after then now whenever I turn on my laptop it shows me this message:

No boot device found . Press any key to reboot the machine.
  • What did you actually install Ubuntu to? It seems that your motherboard can't detect a proper boot device, which means your Ubuntu installation broke- or, the device you installed Ubuntu to is no longer plugged in. I would try installing from a bootable usb, and make sure that you installed it to your hard drive. – negusp Sep 24 '16 at 22:18
  • Is ur laptop dual booted?where did u install? Ubuntu needs some unallocated space to install. – minigeek Sep 25 '16 at 16:20

For solving this kind of error follow the steps given below :

1 ) set boot on secure mode (UFEI mode ) .. For this open boot settings which can be open by Pressing f12 or f2 or f4 button repeatedly .

2) now reinstall your linux system

First option

try this if it does not work try below one.

Try entering your BIOS menu by entering f10 or f9 or f12 or delete key OR any other key that you can try.

Once there, there will be an option for boot order and in that after selecting OS boot there will be options for choosing windows OR ubuntu as first option.

In my BIOS for rearranging I have to press f6 and f5 yours may be different.


second option

Make a live Ubuntu USB or CD and boot to it. Select "try Ubuntu without installing" Once there, open terminal and execute the following:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

After installing, open it by executing boot-repair and select recommended repair then follow on screen instructions.

After booting for first time execute sudo update-grub to add all entries and you are good to go

  • Cannot add PPA : 'ppa:yannubur' . Please check that the PPA name or format is correct . – Sami Patel Sep 25 '16 at 6:43
