thanks again, TehGhodTrole, for your answers. Checksums are correct, btw.. I've tried 3 different .iso downloaded from 3 different mirrors. But I'm happy because finally I could install! . If interested, read how I did. The iso and unetbootin were in disc C: so I execute it, from inside windows xp. The live installation was created in C: and there was created mint4win. I wanted to install definitely in E: so i tried copying mint4win and the iso file to E: and executed mint4win from there. There was created amother live mint. I reboot and selected mint, from inside mint I click on Install Mint, and voilá!! It worked!! Now I have Mint 14 in drive E an WXP in C: (and still remains the live version in C: , i expect I can use it for testing in the future.. if need to) . Mint works great, is very fast, I'm learning and configuring it, but I like it very much! Thanks for your assistance, TehGhodTrole, and sry for difficulties understanding my english. I'm very happy with Mint and with this forum. Juan, from Argentina.
