Cannot make bootable usb from UDF .iso

I’m running Ubuntu 24.04 64 bit. I have other distros available. I’ve made many bootable USBs to install programs, usually linux distros. My PC does not have a CD/DVD drive. I recently wanted to make a VN running Windows XP. I was easily able to find a .iso installation file to download, but when I used dd to copy it to my USB device Ubuntu does not detect the USB. Disks does, and so does gparted, but I can’t make it boot. What should I do?

This site is about Ubuntu. But I have seen that Windows does not support writing the ISO with dd. Best to ask on a Windows format since XP is very obsolete now. and downloading from some unknown site may not be a valid XP image and have all sorts of scams built in.

If your trying to create an iso from Windows, try ‘Rufus’. I use Ventoy to boot all my iso’s. It rarely fails.

Rufus (running under Wine) doesn’t detect the .iso file. I’ll try Ventoy, thank you.

People install XP and Windows 7 in virtual machines for reasons. I was hoping one such person would see my problem and tell me how they do it. I doubt anyone on a Windows forum would know how to boot a usb on a Linux machine.

There are many who run older Windows in a VM. I do not anymore, but when I did, a bootable USB was not needed. Can you place the Windows ISO on your Ubuntu filesystem somewhere ( ~/Downloads/ISOs ) for example, and then point your hypervisor to the ISO when installing the Windows VM? In the VM setup step, you would tell the hypervisor what OS you want and select the appropriate filesystem for the VM. You could also point the hypervisor to a USB that contains the ISO for installation.
