My laptop currently runs Windows 11 and handles office work reasonably well, but Windows often uses around 40–70% of my 8GB of memory. When I try to play games, I sometimes get severe stuttering and unstable performance. I'm considering installing Linux for gaming, customization, and general experimentation, possibly CachyOS, while keeping Windows available for work and compatibility.
I'm thinking about partitioning the laptop's single internal drive and setting up a dual-boot configuration. However, I've heard that Windows updates can occasionally change the UEFI boot order or interfere with the Linux bootloader, potentially making the system difficult to start.
Would it be possible to put the Linux bootloader on a USB flash drive so that plugging it in would show a menu for choosing Linux or Windows, while leaving the laptop to boot Windows automatically when the USB drive is absent? Would using a single drive with separate partitions be safe, and is this practical for gaming?

Before committing, check whether your games work with Linux through Steam Play/Proton. Many do, but some multiplayer games with kernel-level anti-cheat systems may not work. Also, switching operating systems won’t automatically solve every performance issue: with only 8GB of RAM, lowering background programs, upgrading the memory if possible, and checking temperatures may help just as much. CachyOS can be fun, but a more established distribution may be easier while you’re learning dual-boot basics.
Installing Linux on the same internal drive with separate partitions is generally fine as long as you resize the Windows partition carefully and leave the Linux partitions untouched. Make a full backup first, disable Windows Fast Startup, and avoid forcing the machine off during updates. Windows changing the boot order is inconvenient, but it usually doesn’t mean your data or Linux installation has been erased.
Running Linux from a USB flash drive or external disk is useful for testing, but it may be much slower than installing it on the internal SSD. Booting and launching applications can take noticeably longer, and games may suffer from the storage bottleneck. For gaming, Linux on the internal drive is the better option if you have enough free space.
Dual-booting can be a good transition strategy. Keep Windows for programs and games that don’t work well on Linux, then use Linux for everything else and gradually move over. Most Windows updates don’t destroy the Linux installation; the more common issue is that they change the UEFI boot order so Windows starts first. That can usually be fixed from Linux by restoring the preferred boot entry. It’s still wise to back up important files before changing partitions, and keeping personal data on another drive is even safer if your laptop supports one.
A USB bootloader is technically possible, but it’s not necessarily the most convenient or reliable setup. The USB drive would need to stay connected and working whenever you want to start Linux, and accidentally losing or damaging it could make Linux harder to boot. A normal UEFI dual-boot installation on the internal drive is usually simpler. You can also select an operating system from the laptop’s one-time boot menu when needed.
