[rear-users] Help migrating Scientific Linux 7.2

I have a Lenovo S30 that I have SL7.2 installed on an SSD, sda. I want 
to try and migrate to a Lenovo P510 that has a NVMe SSD, nvme0n1 I 
believe. I also have a second local SSD that I just plan to physically 
move to the P510.

I've created a REAR backup on the S30, but when I try and restore to the 
P510 I have various partition errors. The current ones I get are in 
marking the initial partition bootable I think, or in creating the 
partitions. It basically says the partition doesn't exist.

REAR seems to select the correct nvme0n1 disk, but is trying to mark 
partition 11 bootable, which isn't a partition that I have, or don't 
have at that point in the recovery.

lsblk of the disk I want to migrate on the S30:
[root at S30 myuser]# lsblk
sda               8:0    0 238.5G  0 disk
├─sda1            8:1    0   512M  0 part /boot
└─sda2            8:2    0   238G  0 part
   ├─vg-swap     253:0    0     8G  0 lvm  [SWAP]
   ├─vg-sl7      253:1    0    20G  0 lvm  /
   ├─vg-tmp      253:2    0    10G  0 lvm  /tmp
   ├─vg-opt      253:3    0    10G  0 lvm  /opt
   ├─vg-var      253:4    0    10G  0 lvm  /var
   └─vg-images   253:5    0   120G  0 lvm  /mnt/images

disklayout.conf on the S30 for the filesystems I want to migrate:

Now, I wonder if my problem is ReaR backed up more than just the "system 
drive" sda?
