If this post if out of place, I apologize - I googled to try and find an appropriate message board to post this on and it kept coming up with this board. If it belongs somewhere else, please let me know and I'll move it, or the mods can...
I'm at wits end with this one.
I use rear (Relax and Recover) to do a full system, bare metal backup. I'm using lvm to encrypt the /home partition on this system. The partition layout looks like this:
/dev/sda1 * (boot) - type Linux
/dev/sda2 - extended
/dev/sda5 - the vg with / and /swap and /home - home is the only encrypted partition
I can't remember if I originally installed Linux UEFI or not, but now that I have one system booting, the harddrive shows up under "Legacy" options in the boot menu.
The original system that the OS was installed a machine I put together with a Gigabyte motherboard. I can backup/restore to another system - same make of motherboard, different harddrive with no problems. I have several Dell Inspirons - a few 3668's and a 3670. When I try to restore to them, they won't boot. They go into some sort of Dell "recovery" mode and the system starts scanning the disks. I can turn that option off in the BIOS - basically, it means that the computer can't find a way to boot from the HD.
On one of the 3668's, Windows 10 happened to be on the HD before I performed a "restore" from my USB stick -( I created a USB stick that boots rear and holds the restore image and the boot record on one USB key for ease of use. ) I was playing around in the BIOS on that system, the one that had WIndows 10 on it previously, and SOMEHOW it was able to boot in Legacy mode.
The 3670 was unable to boot from any mode and I've tried everything. I've tried an mbr restore by booting into a livecd and mounting the boot partition and the root partition this way...
vgchange -ay CoinScience-vg
mount /dev/mapper/CoinSciece-vg-root /mnt/tmp
mouint /dev/sda1 /mnt/tmp/boot
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt/tmp/$i; done
chroot /mnt/
grub-install /dev/sda
update-grub
I've tried the boot repair disk - https://help.ubuntu.com/community/Boot-Repair
and countless other things that aren't coming to mind right now and it's driving me crazy - particularly since SOMEHOW, I was able to boot off of the HD in the 3668.
Can anyone PLEASE point me in the right direction?
Thank you in advance! - A
