First:

1.  Back up everything on all of the drives in the old computer.

2.  Take an image of the system drive in the old computer.

3.  Copy the above to another device and put the copy off-site.


What is the make and model of the computer?


What failed?


What do you need to do tonight?  E.g. what software do you need?  What 
version?  Do you have data files created with a particular version that 
you need to open?

What is the make and model of the new computer?

What image file did you download (please provide URL)?


Please verify the checksum of the file you downloaded.

Did you put the image file onto an optical disc or a USB flash drive? 
What make and model?


Please verify the checksum of the burned media.

If you put the image on an optical disc, perhaps your optical drive is 
having problems (?).

Good.

Firmware for what device?  Is the device required for what you need to 
do tonight?

One failure can cause a domino effect, even if the later stuff is 
otherwise okay.

Your idea, below, is valid.


Another idea is to pull the HDD(s)/SSD(s) in the broken computer and put 
them into the new computer.

Transient errors with FOSS project infrastructure servers are all too 
common.  A corollary to Murphy's Law, the likelihood of a failure is 
directly proportional to the urgency of the need. ;-)


If you want to use netinst ISO's, you need a local package caching 
server with at least one valid package for all needed packages.  I've 
used approx in the past, and it seemed to work.  I hope it rejects/ 
isolates downloaded packages with bad checksums and/or signatures, but I 
have not confirmed this.


Downloading installer images and/or supplemental images to obtain all 
the packages you need is another way to protect against mirror server 
failures, and the only way I know of to install onto air-walled machines 
(burn to optical disc, as USB keys can be rooted).  If you select a 
mirror during installation and the mirror is having issues, you can 
exit, pull the Ethernet cable, start over, select no mirror, and the 
installer will be forced to only use the packages on the installation 
and/or supplemental media.


I don't know if you need software that is only available on Jessie.  I 
tried Jessie (8.2) a while back, and found it had issues.  I currently 
run Wheezy with Xfce, and install from this image:

 
http://cdimage.debian.org/cdimage/archive/7.9.0/amd64/iso-cd/debian-7.9.0-amd64-xfce-CD-1.iso

Or, to conserve bandwidth:

 
http://cdimage.debian.org/cdimage/archive/7.9.0/amd64/jigdo-cd/debian-7.9.0-amd64-xfce-CD-1.jigdo

It is possible that the Debian mirrors are having issues, and/or the 
caching servers between you and the Debian mirrors.  I don't know how to 
check.

Good idea.

Further clues that something is wrong with the Debian servers and/or the 
caching servers between you and the Debian servers.

Once you partition a disk correctly, you shouldn't need to partition it 
again.  That said, partitioning (correctly) won't hurt.


Even if I use existing partitions, I usually erase dm-crypt containers 
and format the file system.

If you're using MBR partition tables, you only need to wipe the first 
megabyte of the system drive.  If you're using GPT, I believe you should 
also wipe the last megabyte.  (The Wheezy installer seems to use MBR; I 
haven't experimented with switching my motherboard to UEFI and seeing if 
I can get GPT with Wheezy and/or Jessie.)

I find that taking good notes helps preserve my sanity when I'm under 
pressure.  Capturing console sessions with cut/paste or 'script' is 
ideal, as it eliminates typographic errors.  And, good notes become even 
more valuable latter.

On Wheezy, I use:

1.  ext4 for /boot -- GRUB doesn't seem to understand btrfs.

2.  btrfs for everything else -- to detect bit rot.
