Recently got a laptop with Windows 10, I went ahead and installed Kubuntu 17.04 properly. Never used Windows since and today I made the mistake of using it. Before shutting down it installed updates which removed traces of the grub. I have not been able to boot into grub since.
I went ahead and shut off the Windows 10 hibernate feature here: Installation fails on Grub (Read only EFI partition?)
I also turned off the Windows 10 fast start feature.
I cannot use the internet on the live CD because it needs a kernel update, there's no ethernet port, and the dongle has only one USB port available for the Live Disk.
I've booted up a live disk with 17.04 for 64 bit systems and have done the following.
Disk layout From the output of -fdisk -l i know the following:
/dev/nvme0n1p1 - efi (100mb)
/dev/nvme0n1p5 - 23.3 gb kubuntu install
/dev/nvme0n1p6 - home (100gb)
I tried the following procedure several times:
sudo mount /dev/nvme0n1p5 /mnt
sudo mount /dev/nvme0n1p1 /mnt/boot/efi
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt
grub-install /dev/nvme0n1 (is this the right location?)
update-grub
There are input/output errors appearing when updating grub, but at the end it says the boot configuration file was updated. After doing a --recheck,it still shows no errors.
I have also done the steps for the thread below on different attempts: How can I repair grub? (How to get Ubuntu back after installing Windows?)
After doing these steps I exit chroot and sudo reboot. However I am always brought back to Windows.
Is there something I'm doing wrong, and is there anyway I can boot into grub?
Sincere thanks.
