If the first partition is a primary partition it's no issue. If it is inside a extended partion it gets tricky, because the extended partition acts like a kind of container. - From your description I guess it's a boot partition, which normally is a primary one. In that case just delete it and recreate it afterwards. Note: you may need to reinstall you bootloader afterwards (due to the changed partition data) and don't forget to toggle the bootable flag for that partition. If it's an extended partition I fear that my experience doesn't suffice to give you qualifield hints as I try to avoid them. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJP8qSkAAoJEJwwOFaNFkYcKSIH/i1USa0uUOGqfwaYZeJf9fhA tSshu2Hu74KZZedkoVgu/zWIYpbPdu1al60elUR20TGXVtE7FXukpakjYLCb/50i Izj9RAhkbk719TbeJ78Vmu7hVn+zXGMBsoRM6WsrLlm0rw1WhrRElunbkJ6qeURS Bw2ZecSsnrxa3V89fizFHbQkWb15iN0O5afIbgLGgiwtzxhRCNRSNWJrNKpHiu2n tnGO7A+0wWDbV7d2ua8mCwKYBa+Rxs9HerENaOY4jQaA8nxJoBW/Pplb7OZA5KZ0 q/Cv8MFhuMjci4EQ1RNNNucmTqzGZ4uLmhWrXNdzG0TKZ2IkvBKXDeptb+bs810= =SBZ0 -----END PGP SIGNATURE-----
