Hello all, an update:

I installed Ubuntu on a new SSD in my desktop PC, then installed Bitcoin Core, downloaded the blockhain.

Unplugged the LAN cable (no wifi card).

Made a new wallet (TestWallet) which created the wallet subfolder in the .config

Copied old 2010 %appdata%\bitcoin folder (wallet.dat and all others) to a new subfolder at same level as TestWallet on Ubuntu. Added the new wallet which I presume was then validated against the downloaded blockhain, took a while.


This is good news, right? I've ordered a Ledger Nano.
