I tried to change my laptop disk following the instructions found at

I'm not sure I did everything right as there are some mistakes and
not everything is clear.
In particular, with cfdisk, I initially chose the gpt label type
because this was the default, so that I thought that this was OK.
But "grub-install /dev/sdb" complained ("this GPT partition label
contains no BIOS Boot Partition; embedding won't be possible.
[...]"). So I changed it to MBR with gdisk as explained on
https://unix.stackexchange.com/questions/61142/remove-gpt-default-back-to-mbr
Note: /dev/sdb corresponds to the new disk connected via a SATA-USB
adapter for the transfer.
Then "cfdisk /dev/sdb" showed:
Disk: /dev/sdb
Size: 931.51 GiB, 1000204886016 bytes, 1953525168 sectors
Label: dos, identifier: 0x00000000
Device Boot Start End Sectors Size Id Type
/dev/sdb1 2048 1050623 1048576 512M 83 Linux
/dev/sdb2 1050624 1953525134 1952474511 931G 8e Linux LVM
This ended up with the following:
# grub-install /dev/sdb
Installing for i386-pc platform.
Installation finished. No error reported.
# update-grub

done
Then I unmounted everything related to /dev/sdb.
But after changing the disk and booted, instead of getting GRUB,
I got PXE-E61 and PXE-M0F errors, and also
────────────────────────────────────────────────────────────────────────
BootDevice Not Found
Please install an operating system on your hard disk.

Note that the disk itself is recognized since the system allowed me
to do a quick check on it (no errors).
So, what could be wrong?
It looks like you've forgot to mark boot partition (/dev/sdb1 ?) as
'Active'.
It is necessary to do for DOS\MBR-style partition table, so stage-2
bootloader could be found during boot process.
You've got PXE-* errors because BIOS tried to boot from network using
PXE\BOOTP and failed.
