I upgraded my CPU (but not motherboard) and a UEFI Debian installation I have no longer works!
For future reference, is there a way that's possible to have a Debian installation that's installed to a USB hard drive be able to boot from two (x86_64 / x64 / amd64) computers?
If so, what would I need to do?
I booted a live Debian session and chrooted into the installation and did with X replaced with the letter that the live session gave.
More specifically, if I remember correctly I had done.:When I reboot, it just doesn't detect anything. It's not like Debian boots but has errors; it just doesn't get detected at all.
Could someone please help me fix this?
Also, is it possible to make it so that I can boot the USB installation on two different computers? If so, what would I have to do?
I also vaguely recall having done in different rescue attempts of mine, one attempt outside the chroot (in the live Debian) and one inside the chroot.
Any input would be GREATLY appreciated!

Code:
grub-install /dev/sdX --target=x86_64-efi --efi-directory=/boot/efi/
More specifically, if I remember correctly I had done.:
Code:
cryptsetup open --type luks /dev/mapper/sdX3 sdc3_crypt
Code:
mount -o autodefrag,compress=zstd,subvol=@rootfs /dev/mapper/debian-vg /mnt
Code:
mount --bind /dev/pts /mnt/dev/pts
Code:
mount --bind /dev /mnt/dev
Code:
mount /dev/sdX2 /mnt/boot
Code:
mount /dev/sdX1 /mnt/boot/efi
Code:
chroot /mnt
Code:
grub-install /dev/sdX --target=x86_64-efi --efi-directory=/boot/efi/
Code:
update-grub && update-initramfs -u && updategrub
