My primary PC died last month due to what I believe is a motherboard error. My EVGA board displays "FF". The fans, drives, everything powers up as usual. But I don't hear any beep, no POST, no BIOS, just nothing.
Since then I've taken up residence on a box much more modest than what I'm used to, but I've used it as an opportunity to learn Linux. Nothing like jumping in head first.
Luckily I have a backup wallet.dat file taken at some point after my last known transaction. I changed the filename of the file in the directory, then renamed my backup as wallet.dat and loaded up Bitcoin Core on Linux Mint 13 Maya.
It was partially successful. I could view and export a list of every transaction I've ever made with my desktop wallet. I opened my CSV file in Calc and found the total sum of transactions left the balance equal to what I remember last having in the wallet.
However, the wallet has no balance and all the transactions have a "conflicted" status. Do I need to download the blockchain first? Is it worth my time to download bootstrap.dat?
After my funds are accessible in Bitcoin Core, how do I then move them to Electrum?
