Something with my installation of Windows has gone seriously wrong, so I was looking to reinstall Windows 7. However, since I don't have an optical drive on my machine, I was attempting to make a bootable USB drive. The most preferable option would be to use the tool provided by Microsoft, but of course that only works on Windows. I was playing around with some alternative tools to create an install thumbdrive such as WinUSB and UNetbootin, which involved a lot of messing around in gparted as I tried and failed to boot from the USB drive.
Eventually I decided to just create a Windows VM in VirtualBox and utilize Microsoft's own software, except now Windows won't recognize my thumbdrive; I'm getting a fairly generic "Code 10" error when I try to inspect the drive in the device manager. I also tried using it on my Mac, but it won't recognize the device either.
Ordinarily I'd assume that I massively corrupted the drive in some capacity, but I still am able to use it without issue on Ubuntu, so I'm assuming I can still salvage it in some way? I've tried formatting it in FAT/32, NTFS, leaving the space unformatted, etc, but the other OSes still refuse to read it.
Any suggestions on how I can regain access to my thumbdrive on Windows and Mac?
