Disk 2 is now the selected disk.

There is no partition selected.

Ive tried windows disk management , Partition and pargon Partition manager with no luck . Can anyone suggest what might be the problem ?

I thought if the partition has a * to the left of it that means it's already selected. What happens if you issue the "active" command to make it active, rather than attempting to re-select partition 1?

In vista attempting to re-select a selected partition would result in it saying "Partition 1 is now the selected partition.", maybe the message you're seeing is specific to Windows 7? I'm not using Windows 7 here so I couldn't tell you offhand.

BTW, for what it's worth, if diskpart doesn't work for you I know for sure that GParted can do this easily.

I just use UltraISO (trial) load ISO and select Bootable>Write Disk Image. It will format and create a bootable USB flash from scratch. You can even load all kinds of other apps and files on there afterward as long as you don't mess with the ISO files which must remain in the root.

However if you want to add other ISO's to make bootable on the same flash you need a boot manager which is hyper complicated. Anyone know an easier way?
