[Bug 1839894] Re: Installing Ubuntu 18.04.3 LTS alongside Windows 10 (Dual Boot) causes grub install to fail with fatal error

[Rohan Paul]

Thanks for your reply.

I had already disabled Fastboot in Windows.

I ran `chkdsk /f /r` from Windows on the EFI partition and then tried
installing Ubuntu. The installation succeeded but I was not able to boot
into Ubuntu. I used bcdedit to add grubx64.efi to the boot path but even
that did not help. To make matters worse, when I tried reinstalling
Ubuntu, I started getting the same error again - "grub-install
failed...this is a fatal error". Unfortunately this time, even `chkdsk`
from Windows failed to resolve the issue. So I used `Try Ubuntu` option
from the live usb stick and ran the commands you suggested for my EFI
partition:

sudo fsck /dev/nvme0n1p1
sudo badblocks /dev/nvme0n1p1 -v

There were no errors reported.

I have spent over a day now on this and am really not sure what is wrong here.
I would really appreciate some help/insight. 
Let me know if any more info is required.
Thanks.
