Attempting to Dualboot, But Unable to Boot to USB?

asked 2018-09-30 18:06:13 -0500

I've been trying to dualboot my Fedora and Windows 10 for a while, since I don't want to sacrifice my ability to play games such as Rainbow Six Siege and Dirty Bomb just yet. However, when I plug my Windows 10 bootable USB into the computer, no matter what slot, I cannot seem to boot to it. Whenever I open my BIOS (motherboard is an MSI Z370-A Pro), it redirects the USB to the Fedora grub instead of to the bootable copy of Windows 10 I chose.

I recently upgraded my computer in the efforts of figuring this out, changing the CPU and motherboard, but despite this the issue persists. The only real solution I've been able to get for this is to run Scrub and just wipe Fedora or Ubuntu completely from my SSDs - defeating the purpose of dualbooting altogether.

Get current win 10 iso from and then use WoeUSB (available in Fedora) to create a bootable USB compatible with BIOS and UEFI.

To boot your computer from this USB stick once, after computer turns on, hit F11 and choose USB drive from boot menu.

In my experience the easiest way to dualboot Windows with Linux was to install win first (and allow it to create its recovery partitions) and then install Linux. That way you won't have to deal with fixing boot process, grub2 will pick up windows and offer it as a boot entry. When installing Linux as first, in some instances you have to later (after win installation) re-set it's partition as bootable and rebuilt grub2 config or reinstall grub2.

I've downloaded the win10 iso on FIVE DIFFERENT DRIVES, and it isn't being recognized. Five BRAND NEW, UNTOUCHED DRIVES.



I don't even want linux anymore. I just want my $800 upgrade to not be completely in vain. I will not give Linux a sidelong glance or a singular popcorn fart ever again if my computer will JUST. BOOT.

I have used Rufus, Fedora Media Writer, Media Creation Tool, and other windows-compatible tools via a family laptop I've been loaned. Each of these allows both BIOS and UEFI compatibility. None of my drives, whether loaded with Ubuntu, Fedora, or Windows, will boot on my desktop. I have replaced the SSDs, the motherboard, the CPU...I have disabled SecureBoot and combed through my BIOS settings...I have wasted more money than I ever wanted to on this upgrade, and the issue still persists. How? What is the root of this?

Now I'm getting full gibberish instead of a short series of errors....

I'd update UEFI to the latest version, restore its settings to defaults and start again from there (without any changes in UEFI). It's the common denominator of all failed attempts to boot (since you've already tried three different systems, five USB sticks and three tools to create bootable USB drives).

Who did you pay for Fedora ISO? It's free for everyone:

Here you can get free updated ISO's with latest updates already incorporated:

That gibberish probably contains clues into what's wrong, just as your rant above.

I paid a USB seller that pre-loads USBs with the specified OS. It's been like two months so I don't remember the name but it worked first try my first time installing Fedora. Suddenly and without any reason it got corrupted from the act of booting. Otherwise I know ISOs are free.

And when I say gibberish, I mean legit gibberish. As in, not even words. Not even letters. Just scattered pixels forming a wall of black, white, blue and green. There are no clues.

Keep this thread on subject (try my previous suggestions on booting from USB and report any progress).

Any other issues (visual artefacts - clue pointing at GPU hardware/driver issue) should be brought up in a new question, with sufficient details about hardware (gpu model, driver), running system and circumstances.

I guess buying preloaded Linux USB is ok when you're completely new to this. Later, when you already know that it's not actually that difficult to make USB stick bootable, it's safer to create one yourself - that way you're sure that it contains only what you wrote on it.
