dell xps 15 7590 (Core i7-9750H) (NVIDIA GeForce GTX 1650, 4 GB, GDDR5)
ubuntu 20.04.1 LTS (laptop shipped with win10 - wiped windows and installed ubuntu ~1 month ago)
bios version 1.8.1
as of 5 days ago laptop boot freezes at dell splash ("ubuntu" never appears at the bottom). only difference between this boot and last successful one was that i had a hdmi connecting laptop to a monitor this time (never connected previously, during boot or otherwise). have been trying to repair this weekend with no joy.
Advanced options for Ubuntu i can boot recovery mode just fine. the os partition seems okay.
dell pre-boot diagnostics returns all-clear, but then says "no bootable device" when it tries to boot.
there are many posts here regarding boot issues. i've tried what i can to no avail. things i have tried:
- booting older kernels (5.4.0-45-generic and 5.4.0-42-generic)
- disabling secure boot (BIOS system info says "signed firmware update is enabled" so i didn't expect this to work. also there's been no bios update since ubuntu install)
- disabling all options in bios boot order (ubuntu, ubuntu firmware updates, windows boot manager), created new boot option for shimx64.efi, then rebooting
- replacing "quiet splash" with "nomodeset" in /etc/default/grub (i've read about nvidia issues)
- boot repair from usb, "recommended" option. only difference now is on boot dell logo appears, disappears for 3 seconds, reappears. pastebin results. i also ran the "boot info summary" option (after "recommended"... my mistake) and have this pastebin
- in recovery mode i checked /var/log/dmesg and syslog for obvious signs of error. they might as well be written in klingon! :-)
- in recovery mode i tried updating grub bootloader, tho i think boot repair already did this
- from usb "Try Ubuntu", i checked filesystem:
sudo fdisk -l Device Start End Sectors Size Type /dev/nvme0n1p1 2048 1050623 1048576 512M EFI System /dev/nvme0n1p2 1050624 500117503 499066880 238G Linux filesystem sudo fsck -f /dev/nvme0n1p2 fsck from util-linux 2.34 e2fsck 1.45.5 (07-Jan-2020) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure``` Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/nvme0n1p2: 288820/15597568 files (0.8% non-contiguous), 5256908/62383360 blocks
any help would be appreciated. if there's more info required let me know. i could reinstall the os again but i want to know why this happened and how to prevent it in the future
