I dropped my HP Pavillion laptop and I'm now having problems accessing windows and grub. I have ubuntu 18.04 and windows 10 installed. I was using the grub bootloader that came when I installed ubuntu. After dropping my laptop, grub will not show but (thankfully) ubuntu boots eventually. My screen stays completely black (not even lit up black where you can see it's turned on) until I can see the ubuntu loading screen.

I tried to reinstall grub using the boot-repair recommended settings which didn't work. I ran fdisk -l and these are the partitions detected

Device          Start        End    Sectors   Size Type

/dev/sda1        2048     534527     532480   260M EFI System

/dev/sda2      534528     796671     262144   128M Microsoft reserved

/dev/sda3      796672 1807442666 1806645995 861.5G Microsoft basic data

/dev/sda4  1910734848 1953517567   42782720  20.4G Windows recovery environment

/dev/sda5  1807443968 1889363889   81919922  39.1G Linux filesystem

I'm not sure how to proceed. I want to be able to use windows again, even if that means losing my data since I can't afford to buy another copy and I'm using the one that came pre installed on my laptop so I don't have any CDs or such for it. I don't have an external hard drive to be able to back up my data. Any help would be deeply appreciated.

EDIT:
I took a look at the paste generated by boot-repair. Early in the file it says this:

============================= Boot Info Summary: ===============================



 => No boot loader is installed in the MBR of /dev/sda.

My hard disk is not partitioned in order. When I use the disks application on ubuntu, it says that /dev/sda is free space. Here is a picture of the disks gui.

From left to right, the partitions shown in the image are /dev/sda1, /dev/sda2, /dev/sda3, /dev/sda5, /dev/sda, /dev/sda4 and then /dev/sda again.

Some more info:

I'm unable to enter my UEFI menu. When I tap the f10 key to enter the menu, the screen stays completely black with no backlight and I can hear beeps when I press certain keys (e.g if I keep tapping the f10 key). I think the UEFI menu is loaded and running but not displaying.

  I am not sure which physical damage would cause the described behaviour except if you had grub+windows on one physical disk and Ubuntu on another, and the drop damaged the windows drive (or loosened the connection). Do you have multiple drives installed? Are you able to access BIOS/UEFI settings?

  It would help to have more information about your Laptop Model. Was there a Win10 preinstalled or is it an upgrade? Some HP Notebooks can recover with pressing [F11] at the boot. Some are more complicated: support.hp.com/us-en/document/c04742289 ... Sometimes you'll just need a bootable win10 install medium. But every step could lead to a data loss in Win or in Ubuntu... It would be good to mount your Windows partition from Ubuntu and save the data external as first step.

  @danzel I have a single HDD drive. My laptop was on and running Windows at the time I dropped it. I'm about to reboot now to see if I can access UEFI.

  @LupusE I can't find the exact model number from linux but I know it starts with "15-ab". I'll reboot and try pressing F11 now.
