I'm having Windows 8.1 ISO file. I also have 7.9GB USB. I wanted to find program which would help me install Windows next to Ubuntu to play games.

So I managed to use UNetbootin but it didn't work. It booted and displayed "Default" as only menu. Whethever you did wait 10 seconds as it asked or you clicked on Enter, it just refreshed and restarted counting down.

Later I used: root@Rik-PC:~# sudo dd if=/home/rik/Desktop/teddy.iso of=/dev/sdc | pv -s 20G, 0B/s for about 5 minutes, kinda disappointed me.

Do you maybe know another ways?

Short expert summary and practical path forward based on the posts by , and .

The symptoms reported (UNetbootin showing a single “Default” entry and a raw dd write that did not produce a bootable Windows installer) match known behavior: Unetbootin is not reliable for Windows ISOs, and simply imaging a Windows ISO with dd usually does not make a bootable Windows USB. (docs.mrchromebox.tech)

Most reliable Linux-native options today are WoeUSB (or WoeUSB‑ng) and Ventoy. WoeUSB writes a proper Windows-style USB (supports legacy and UEFI boot and can target NTFS so large files like install.wim are handled correctly). A typical device-mode command looks like:

sudo woeusb --device /path/to/windows.iso /dev/sdX --target-filesystem ntfs

(backup any data on the stick first). (github.com)

If the Windows image contains files larger than FAT32’s single-file limit (4,294,967,295 bytes), a FAT32-formatted stick will fail to hold that file; that is why an NTFS target (or a tool that handles the UEFI/NTFS bridge) is often required. (en.wikipedia.org) Ventoy is a convenient alternative: install Ventoy once, then copy ISO files to the stick and boot them directly (works well for multiple ISOs, including Windows). (ventoy.net)

Practical checklist (do before any write): back up the USB, confirm the target device node (not a partition), verify ISO checksums, check firmware boot mode (UEFI vs legacy) and Secure Boot settings, and try a different USB port or stick if the first attempt fails. Note that BartPE is a Windows-based approach (as mentioned by ) and VMs (as suggested) are fine for testing but will not provide native gaming performance.

Last command sudo dd has finished, after booting, nothing happened, it took about a minute to go through USB and then it went to Internet, DVD and then HDD according to order.

You might want to look into Bart's PE which will allow you to boot into a USB Windows environment. I seem to recall reading somewhere that Windows 9 will come with a tool which allows you to build a Windows USB.

VMware and have windows on virtual machine?

I wish I could but it's not gonna happen. My PC isn't a hardcore rig. If I start virtual machine and install Windows on it and then try to play game, I expect to have many hardware lags, which I can avoid by just installing Windows next to Ubuntu.

@Reverend_Jim Why wait for Windows 9? Rufus (a program) did fantastic job installing bootable Ubuntu 14.04 on USB. The only program I see from BartPE is .exe, that doesn't really like Linux, you remember?

Before you suggest anything else. Today is "tomorrow" since I posted this topic. I could bump in USB, modify it's content etc., now when I'm inserting USB it prompts me error.


The faden out parts are my name something like "joseph" or "michael" or "rik" or "aiden" (I do see them, but for personal privacy I did fade 'em out with GIMP)
