[SOLVED] No Arch in BIOS after replacing home with backup home

I don’t see anything that stands out in your grub.cfg. What happens when you boot the last menuentry under advance options.
You may have to re-create the initramfs

OMG i was just checking my backup device and the content of folder "oldandstabile" just to realize that the subfolder called /home was empty! this must have been why!

this here is 1 week old backup and intact https://ibb.co/JjNs7J2

i guess i do this?:

Code:

fdisk -l
# make directory for /mnt/sdb3
mkdir /mnt/sdb3

# create mountpoint for /dev/sdb3 /mnt/sdb3
mount /dev/sda1 /mnt/sdb3

# make directory for /mnt/sdc
mkdir /mnt/sdc

#make encrypted disk accessable
cryptsetup luksOpen /dev/sdc ArchBackup

# create mountpoint for /dev/mapper/ArchBackup /mnt/sdc
mount /dev/mapper/ArchBackup /mnt/sdc

# copy paste backup of home to sda1 and replace /home in destination
cp -ax /mnt/sdc/myusername /mnt/sdb3/home/

is that about right?

with /home empty, if you attempt to log in with a username, it will return back to the login prompt. Are you able to log in as root?

after you hit enter at the grub menu, for your installed system take a picture of where it stops at.

yes, if your missing your user folder in /home you won't be able to login. You need to copy user folder to /home if you have a backup of it.

to login as root, there should be a way to change username to root at login screen, but not sure if arch will allow you to login as root in DE

means this will do it?

Code:

fdisk -l
# make directory for /mnt/sdb3
mkdir /mnt/sdb3

# create mountpoint for /dev/sdb3 /mnt/sdb3
mount /dev/sda1 /mnt/sdb3

# make directory for /mnt/sdc
mkdir /mnt/sdc

#make encrypted disk accessable
cryptsetup luksOpen /dev/sdc ArchBackup

# create mountpoint for /dev/mapper/ArchBackup /mnt/sdc
mount /dev/mapper/ArchBackup /mnt/sdc

# copy paste backup of home to sda1 and replace /home in destination
cp -ax /mnt/sdc/myusername /mnt/sdb3/home/

I think so, that is what I would do.

I would fallback to tty, delete and recreate user (to avoid any further problems !) with it's attributes including home folder. Then login and copy.

i did this

Code:

fdisk -l
# make directory for /mnt/sda3
mkdir /mnt/sda3

# create mountpoint for /dev/sda3 /mnt/sda3
mount /dev/sda3 /mnt/sda3

# make directory for /mnt/sdc
mkdir /mnt/sdc

#make encrypted disk accessable
cryptsetup luksOpen /dev/sdc ArchBackup

# create mountpoint for /dev/mapper/ArchBackup /mnt/sdc
mount /dev/mapper/ArchBackup /mnt/sdc

# copy paste backup of home to sda1 and replace /home in destination
cp -ax /mnt/sdc /mnt/sda3/home/

and nothing changed for me. i still get thrown back to DE-Login after 1 sec

Either go with what tonus says or try the chown command make sure user is owner of the user folder and sub files
