I went ahead and verified the labels on my partitions, and /dev/sda2 is labelled "/" and /dev/sda1 has a label of "/boot".
Like I previously mentioned, I believe /boot is fine since grub loads - I am still at a loss as to why it can not see /. I installed the pendrive into my home PC running 4.4 and /dev/sda2 looks fine. I also ran fsck on it and it is clean.
A while back, it was suggested that I run mkinitrd and include the USB drivers. I tried this, but it still wasn't recognized. If anyone can help me get pointed in the right direction, it will be greatly appreciated. Thanks!
