Ooops my wrong !! (in my excitement) when I ran
Release Name: Linux unetbootin; Ultimate Edition style
Version: 494 ,I didn`t LOOK to see that I could choose a version, so ended up with the default choice
2.7 32bit.
Thats ok; ...so I installed the Release Name: Ultimate Edition 2.6.1 LTS
Architecture: x64 (64 bit)
Codebase: Ultimate Edition 2.6 (Ubuntu 10.04.1 Lucid Lynx)
Environment(s): Gnome
Filesize: 2.5 GB (2,657,875,968 bytes)
MD5SUM: 3cff444b22486be2dfc0c5c49c08bf40
Download: 64 Bit
via unetbootin standard OK no hitches
and also installed the 2.7 32bit that I downloaded via Linux unetbootin; Ultimate Edition style Version: 494 on my USB to a different partition OK no hitches.
There was was no choice for 2.6.1 in the tool so I am currently downloading 2.6 64 bit from it and will check the install to see that it goes ok and what it is (2.6 original or 2.6.1)
