I have made a bootable USB drive with Ubuntu installer and now I can't delete Ubuntu from it. I tried to use GParted and erased the partition table, made a new ms-dos partition table and formatted the drive as FAT32. Now the name of the drive is still Ubuntu 13.04 amd64 and a couple of files and folders from ubuntu installer are still there(eg: wubi.exe, boot and others). I can't delete them because it is read-only. I also tried the following:
sudo fdisk /dev/sdb
partition type: p
partition number: 1
Now, the minimum value of the first sector is 2048 instead of 62 (the drive has 62 sectors /track)
Tried with 2048 as first and all remained the same as before.
I need urgent help, any command or thing that might help. Preferably not stuff like Gutmann wipe :)
