Try repositioning the jumper cable clips to get the most secure, greatest area of contact. On both batteries. Or try a larger gauge cables.

Safest thing to do is just pull it and take it to an auto parts store and have them charge it for free. Least amount of strain on the battery and alternator that way.

Buy a decent battery charger, not just a minder. One that has at least two charging positions (2amp-10amp) and a "starting" (50 amp) option. You will need it in life. I use mine all the time and it has lasted decades. I have a Schumacher (USA) 1052A-PE, slow-fast charge, starting, complete shutoff, spark proof, and reverse polarity protection. Solid state.

Give the battery a full charge. You may have to jump the dead battery a while (no starting) with a good battery. This is to force a charge in the dead battery so that the charger will "see" something hooked up to allow charging power to flow. If the voltage is too low, it will not charge.

Completely draining the battery will reduce life of a lead acid battery. If your battery was older (5 years) you may have put the last nail in the coffin. In any event, after something like this, you would normally want to recharge it immediately to reduce the plates degrading and shorting.

I think windhund116 nailed it, poor connection when trying to jump start it.

Great! As a previous poster noted you needed better contact (most likely)
