after a powr failure when upgrading to Ubuntu 12.10 I have a completely deficient system. It is read only and despite many attempts I failed to remount it read write, fsck and mount -o rmount, rw don't work, recovery mode does not work. I am not experienced with linux and under time pressure because have to write a paper until tomorrow and have only this computer.
Thus I thought it was best to reinstall. I have downloaded the iso on my usb stick on another computer. However, I can't us my startup disk creator as my usb stick is not being recognized as the filesystem is read only. I don't have a bootable usb or disk around (I know that's stupid) and I have no one using linux nearby who could help me create the stick. They all have windows.
Thus my question: Can I create a bootable usb on a windows system but to install on a computer which has Ubuntu on it? The wuby client you can download for windows on the ubuntu site is .exe so it would be no use on a computer that has only linux on it?
