Why this guide exists before the USB stick
Every dual-boot horror story we see starts the same way: someone clicked through a partition screen they did not understand, or an installer defaulted to “use entire disk,” or the Windows drive was already dying and the install was the last write that finished it off. Linux is easy. Recovering irreplaceable data after a wipe is not.
Treat installation like surgery. You want a verified backup and a known-good recovery path before anesthesia. If you only read one page in this series before downloading an ISO, make it this one.
Minimum backup that counts
- Copy Documents, Desktop, Pictures, Videos, and school/work project folders to an external drive you can unplug.
- Export browser bookmarks and password manager data if you use one.
- Note Windows product keys or Microsoft account ties only if you still care about reinstalling Windows later.
- If dual-booting, also back up anything on D: or other data partitions you might resize.
- Open three random files from the backup to prove the copy worked.
Cloud sync folders are not a complete backup if they have not finished uploading or if you never tested a restore. Unplugged external storage plus a second off-site or cloud copy is the adult version of “I think it’s fine.”
Hardware health check (five minutes)
Listen for HDD clicking. Note SMART warnings if you already have a tool. If Windows freezes when copying large folders, stop and treat the disk as suspect - install Linux after imaging, not before. Installing on a failing drive just moves the crash to a new OS.
Free space matters too. Dual-boot needs room to shrink Windows safely. If C: is 98% full, clean or move data first. Installers that cannot shrink partitions cleanly are how people end up with broken boot menus.
Write the plan on paper
One sentence mission: “Keep Windows, add Linux Mint on free space” or “Wipe disk, Linux only.” Circle the target disk serial if you have two drives. Installers show sizes - match size to the drive you think you are touching. USB installers have wiped external backup disks when people selected the wrong target. Unplug backup drives during install when you can.
If this already feels like too many ways to lose data, that is a valid shop ticket: we can image first, then install, then verify boot. Paying for a careful install is cheaper than a clean-room recovery fantasy.
When to stop DIY
When the stack exceeds DIY - drive failures, dual-boot disasters, locked accounts, or a machine that must be online for work tomorrow - contact CCPCREPAIR in Tahlequah. We do diagnostics with a flat quote after we know what is wrong. Call 918-228-5889 or use the form.

At CCPCREPAIR in Tahlequah we see the same pattern repeatedly: people succeed with Linux when they slow down for backups, pick a mainstream distro, and treat the first week as landing the plane - updates, browser, printer - before theming and experimental drivers. They fail when they skip the backup, click through erase-disk options, or paste sudo commands they cannot explain.
Keep a live USB of the same distro in a drawer. It is a recovery tool as much as an installer. When something will not boot, the live session is how you copy files off and read logs without making the problem worse. That habit alone separates calm operators from emergency tickets.
If you share a machine with family, write a one-page note: distro name, username model (not the password), whether the disk is encrypted, and where the backups live. Future you - or a technician - will move faster with that sheet than with a vague memory of a YouTube video from three months ago.
Continue the series in order when you can, but jump ahead if you already know the topic. Every page ends with abort criteria and a path to contact the shop when risk climbs. Linux is easy when honesty about hardware and data comes first.
