Do you want to mount /root r-o? /etc? I think not.


Separating the things that move a lot and the things that are stable is
still a good idea.


For what the OP is up to, mounting the old file systems (on the HD)
until he is satisfied he has everything working right is probably a
good idea.


No, it is an excellent occasion to rework the partitioning, wasting is
not a good idea.

Also, the partitions will probably not fit the new disk exactly, leaving
a useless clump with an awkward at the end.


I have made these partitions:

Device        Start      End  Sectors  Size Type
/dev/sda1      2048  1953792  1951745  953M Linux filesystem
/dev/sda2   1955840  6150144  4194305    2G Linux filesystem
/dev/sda3   6152192 48095232 41943041   20G Linux filesystem
/dev/sda4  48097280 48195583    98304   48M Linux swap
/dev/sda5  48195584 67069952 18874369    9G Linux filesystem
/dev/sda6  67072000 69023744  1951745  953M BIOS boot
Grub installs without error on that drive, but drops me into grub's command line when I boot from it. Then when I do 

boot (hd0,gptN)
for N in 1 or 2 (/boot or /root) it tells me that I have to pick a kernel first. I have these files: 

eben@cerberus:~$ sudo mount -o ro /dev/sda2 /mnt/temp
eben@cerberus:~$ sudo mount -o ro /dev/sda1 /mnt/temp/boot
eben@cerberus:~$ ls -l /mnt/temp/vm*
0 lrwxrwxrwx 1 root root 27 May 25 13:01 /mnt/temp/vmlinuz -> boot/vmlinuz-6.1.0-37-amd64 0 lrwxrwxrwx 1 root root 27 May 25 13:01 /mnt/temp/vmlinuz.old -> boot/vmlinuz-6.1.0-35-amd64 
eben@cerberus:~$ ls -l /mnt/temp/boot/v*
7.9M -rw-r--r-- 1 root root 7.9M Apr 10 15:32 /mnt/temp/boot/vmlinuz-6.1.0-33-amd64 7.9M -rw-r--r-- 1 root root 7.9M Apr 25 15:51 /mnt/temp/boot/vmlinuz-6.1.0-34-amd64 7.9M -rw-r--r-- 1 root root 7.9M May 7 11:10 /mnt/temp/boot/vmlinuz-6.1.0-35-amd64 7.9M -rw-r--r-- 1 root root 7.9M May 22 14:32 /mnt/temp/boot/vmlinuz-6.1.0-37-amd64 

What does it want from me?
The HD (currently sdc) boots fine. The BIOS (or whatever) doesn't offer it as a boot device, but I can do F12 at POST = "select boot device", pick it, and it works.
