I tried to copy the entire arch install onto another hard drive (form HDD [/dev/sda] to SSD [/dev/sdb], both internal).
This is how I tried to do it:
- Live Arch stick
- mounted both root partitions
- cp -a /mnt/HDD/* /mnt/SSD
- same for boot and efi partition
- chrooted into SSD
- reinstalled grub
Everything seemed to work, but the SSD system is not displayed in my computer's EFI. What do I do wrong?
Thanks in advance!
@Paul H.'s way to install grub now worked!
The only problem is that both EFI entries boot the same OS, which is the old (HDD, /dev/sda4) one...
