Install a bootable Windows 10 or Linux image on an external HDD for a friend's PC.
Hello everyone, here are some thoughts on setting up a bootable external HDD/SDD with Windows 10 or Linux Mint. You want to bring your portable OS along with your work and games for use at your friend's gaming PC while staying over. Your main concerns are compatibility, data visibility, and security. If the friend's PC runs Windows 10 and your bootable drive also has Windows 10, could there be any conflicts during startup? Would switching to Linux Mint be a better option in that scenario? When you boot into your personal drive on their machine, will you be able to access their hard drives? I want to keep both sets of drives separate. It seems possible to unmount drives in Windows 10, but does that mean you’ll need to unmount them every time you use the external drive? If the external drive gets infected with malware or a virus, could it affect the friend’s PC too? For safety, I’d like to know how this setup will affect them since it’s not their own machine. Thanks for your advice and any guidance you can provide!
It might lead to issues if you configure the system with UEFI boot and your friend's machine also supports it. The bootloader will alert you that a device is missing if a UEFI setup is used. Verify on your friend's computer whether it uses BIOS or legacy boot. Configure your storage with Legacy Boot instead.
Your friend's drive appears in Windows Explorer, but you'll need admin rights to access folders and files.
If the malware is present, it will encrypt files across several drives, including theirs. While other viruses aren't likely to harm their system, it's wise to avoid risks—unmount their drive so it isn't recognized. Still, installing Windows remains a good idea for gaming. Linux could pose compatibility problems with certain games or programs, but it offers more security and simpler installation. Another solution is using a USB flash drive for Windows; it loads slower than a hard drive or SSD, but you can install Windows onto a bootable USB with Hasleo WinToUSB. Purchase a large-capacity USB (128/256GB) from Amazon and use the provided software to transfer Windows.
Hi! Glad you liked the comments. I have a few more questions. I was surprised I’d need to configure it for Legacy Boot; thanks! I can only see and view files, not edit them—so as long as I don’t accidentally damage anything, I’m fine with that. If I unmount a friend’s drive, do I need to unmount it each time I use his PC? Or does the system remember once it’s unmounted? Also, a USB flash drive could be handy for portability. Will it be slower than using a portable SSD or HDD?
