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.
