I got everything guys, thank you so much!

After days of trying to figure this out, Im so happy now, again, thank you!

Thank you so much, once again I have to ask another question:

The wallet has had around 5-10 transactions, but buy using the commands that BitMaxz mentioned I'll only find one private key? How to I differanciate between the keys that I want?

Also.. lets say that I have all the adresses. Do I then create one wallet in electrum and import every private key into that wallet. First when this is done I'll be able to transfer the remaining coins to another wallet in one single transaction?

Hope to hear from you again

Does this mean that I cant just simply copy the private key from this .dat wallet and import it to electrum? ... and after that just start transfering bitcoin as I usually would using the bitcoin core app?

Also... do you know a safe way to find my master public key only using my wallet.dat and my password?

I understand that this is a sensitive subject, but I did not save my master public key when I was first trying this out years ago...

Thank you so much, I'll try doing this tomorrow!

Hello,

Around seven-eight years ago I downloaded bitcoin core and had some transactions just to try it out. I saved the wallet.dat file and forgot about it. I recently found the file and is trying to download the blockchain once again but it goes so slow and I dont have the ability to let my computer be on 24/7 for weeks. Also it obviously slows down the computer so I cant work as fast as I am used to. In adition to this, some of the possible solutions to this is rooted in using the command line in the bitcoin core app, witch seeme to be very problematic since I have to wait everywhere from 5 minuts to an hour before the app responds to my actions. 

I have research the web for solutions, one of witch is finding my private key and importing it to a wallet such as electrum. I dont know how to do this, and I find it a little scary to trust some of the sources that explains it. The other solutions I have found seeme to revolve around the same principle, but on the other hand it also seeme a little scary for my that is not an bitcoin expert at all.

Do you guys have any experience with this? Any solutions (easy or hazzle) that could solve this problem? I would even love some tips on how to download the blockchain faster.
