Yesterday I was trying to change the power settings of my computer (HP Spectre x360) so that when I close the lid it suspends (which currently doesn't happen, the computer does nothing) when I came across a supposed solution to this issue that implied a kernel update. I "updated" the present kernel that came with the install to the 4.4.25 version, but now the computer doesn't boot up.

In the GRUB menu I get these boot options:

  • Ubuntu, with Linux 4.8.0-46-generic
  • Ubuntu, with Linux 4.8.0-46-generic (upstart)
  • Ubuntu, with Linux 4.8.0-46-generic (recovery mode)

  • Ubuntu, with Linux 4.8.0-45-generic

  • Ubuntu, with Linux 4.8.0-45-generic (upstart)
  • Ubuntu, with Linux 4.8.0-45-generic (recovery mode)

  • Ubuntu, with Linux 4.4.25-040425-generic

  • Ubuntu, with Linux 4.4.25-040425-generic (upstart)
  • Ubuntu, with Linux 4.4.25-040425-generic (recovery mode)

When I choose the first option I get a black screen. When I choose the second I get a purple screen with this message at the top left:

Loading Linux 4.8.0-46-generic ...
Loading initial ramdisk ...

When I choose recovery mode I get a recovery menu:

when choosing the recovery mode

I followed the instructions to do the kernel update here on linuxdaddy.

  • What exactly happens if you choose e.g. the top one, or the recovery mode? – Jos Apr 15 '17 at 12:22
  • What happens if you do the fourth option for 4.8.0-45-generic? And the kernel that you installed from that guide is an old one. That post is from October 2016 – nullmeta Apr 16 '17 at 4:30
  • When I choose that option I get the same message as if I had chosen the second. It stays that way for a while after which I get a black screen. If I choose the 5th and 6th I get the same behavior as the 2nd and 3rd options. Nullmeta - I realized that when I was writing the post. That is why I wrote updated with apostrophes. I followed that guide because in was linked on the comment I mentioned earlier with the solution for my hibernation issue. The author of the comment talked about an upgrade to the 4.8 version, instead of the 4.4.25 one. Hence my confusion. – David Silva Apr 16 '17 at 9:46
