Thanks in advance for the help.

I have a Dell Precision 7540 that has Ubuntu 20.10 installed (previously 20.04). It is a pretty normal installation with a single physical nvme disk, with separate partition for boot and LUKS on the main partition. I can no longer boot past the Grub boot screen. The options I have to select from are:

Ubuntu with Linux 5.8.0-26-generic

Ubuntu with Linux 5.8.0-26-generic (recovery mode)

Both of these options have the same behavior. After 10-15 seconds, it brings me to a (initramfs) prompt. Typing exit gives the following:

```
Gave up waiting for root file system device. Common problems:
 - Boot args (cat /proc/cmdline)
  - Check rootdelay= (did the system wait long enough?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/vgubuntu-root does not exist. Dropping to a shell!

```

Things I have tried:
I have tried booting from a Live USB, and I can successfully mount the LUKS partition. I have installed and run boot-repair from the live USB, and after the repair, it gave me a pastebin link, below, but still will not boot:

<http://pastebin.ubuntu.com/p/HxXj4qfrqS/>

I have also chrooting into my installation and running update-grub, grub-install, and update-initramfs, but none of these have changed anything.

Let me know if there is any other information that would help to diagnose this.

**UPDATE:** I have gotten it to boot, but only after unlocking the LUKS partition from initramfs. By doing the following command:

`cryptsetup luksOpen /dev/nvme0n1p3 nvme0n1p3_crypt`
and entering the password, then:
`exit`
It will boot. **How can I make it prompt me for this instead of timing out and dropping me to initramfs?**
