I use to boot from a USB stick, but today I moved back to the MBR on my primary drive.

I copied all the files from the old /boot to the new /boot, and ran sudo grub2-mkconfig -o /boot/grub2/grub.cfg (along with grub2-install).

Now, I can boot fine, with one bizare exception. After entering the luks encryption password my boot log hangs until I insert the old USB stick. Mind you, its obviously booting fine from the new boot partition, but something (systemd related I suspect) is hanging until it finds the usb stick.

Here is an annotated boot.log

990d80e7-f998-4696-b2db-42145a013d9a is the UUID of the old usb disk 's /boot partition
47a883b5-1bfe-40bb-a9a7-f8791a6d122a is the UUID of the new /boot partition at /dev/sda4

At this point, during boot I insert my usb stick then remove it a second later to workaround this problem. What's the deal though? Is there some vestigial remnant in systemd expecting that disk? Where would I find that?

Any advice would be well appreciated.

You are obviously using LVM - is a partition on the USB disk part of a Volume Group? or still registered as a Physical Volume?

Ah, good question. I don't think so but I'm not 100% sure, here's the output of lvdisplay and pvdisplay: http://fpaste.org/215474/97934214/

You only have the one PV - which would be the primary disk, which means that is unlikely to be the problem.

Looking at your fstab file (which I missed earlier), you have an entry:

UUID=595AA800301BA2C7 /run/media/ramblurr/Seagate ntfs-3g ... 
Which disk is this?

The mount point and fs-type suggest that it could be a removeable disk. Leave it alone if you know what it is, otherwise If you are unsure what it is, then try commenting it out -- insert # in front of the UUID, and then issue sudo mount -a to check for errors, followed by a reboot.

That's an external USB hard drive, another disk entirely. It isn't the old boot stick. I've tried as you suggest, but that disk seems to have no effect. I am having the same hanging boot with or without that external disk plugged in or defined or commented in fstab.
