Hi everyone, I have a small problem and I am absolutely desperate already.
I have downloaded a bitcoin core app and while still synchronising I have sent bitcoins on it.
Afterwards, I found out that my computer' hard drive is not big enough for the file so I tried to dump the private key and use it in another wallet. However, the private key that I receive by the bitcoin core is not accepted anywhere.
Can anyone help me please? I am new to this and not sure what to do...

What does the private key start with -- 5, K, or L?

Also, how did you get the private key?
Code:
dumpprivkey <address>

Also, when you say "not accepted anywhere" what exactly do you mean?

An easy solution is to prune Bitcoin Core:
Quote
To enable block pruning set prune=<N> on the command line or in bitcoin.conf, where N is the number of MiB to allot for raw block & undo data.
Use prune=550, and let Bitcoin Core sync. It still needs to download the full 170 GB, but won't take more than 10 GB disk space on your computer.

Do it with passion, or not at all.

I think its problem is import a private key of a segwit address (P2SH-P2WPKH) into a non-segwit wallet.
What is your "another wallet"?
did you try electrum wallet? "sweep pvt key"

Private keys of segwit adresses and nonsegwit adresses are exactly the same format ( and the same), so no, that's probably not the issue. The private key he has is either not a private key, or somehow encrypted.

To OP:

What wallet are you trying to import it in? Electrum? How many chars is the key you have?

Can you list which wallet that you've tried? You should try Electrum or Mycelium if you haven't try import your private key to those wallet. Also beware when you import/export your private key between wallet, since malicious software could see/stole everything you copy.

Actually SegWit address (Bech32) have different format with legacy address, i've tried import SegWit Bech32 private key to wallet which don't support SegWit and obviously the private key isn't accepted.

I don't think so.

Segwit is simply a different payment script + adress format, it does not generate a different key. A private key can both generate a traditional adress (P2PKH), or a segwit one, (P2SH).

This answer is a bit more indepth about it, https://bitcoin.stackexchange.com/a/70123

This is correct.
Addresses are derived from public keys, which are first derived from private keys.
Private key -> public key -> address
So you can have one (WIF) private key, with different addresses, depending on the private keys.
Ordinarily you can create 2 P2PKH addresses from one private key, by using either compressed or uncompressed public keys.
You can also derive P2PWKH, P2SH, and P2SH-P2WPKH addresses from the same public key (note that segwit addresses are all derived from compressed public keys)

Thanks for the info, but i already know about it. What i meant was private key/wallet import format such as WIF, WIF-compressed, BIP38 (encrypted private key with passphrase, usually for paper wallet) or  mini-private key format (usually for low end devices or physical coins) which few wallet don't support it properly.
