1. Power loss: One of the most common data loss risks with system upgrades is loss of power that could happen at any time. This can make your files and other crucial documents inaccessible to you.
2. Less storage: The system always mentions the storage capacity that is needed to update the system. If you do not have enough space, then you should stop before starting the system upgrade. Upgrading with a lack of disk space could lead to a system that cannot boot and render files inaccessible.
3. Hard drive failure: A hard drive’s health matters a lot when upgrading your system. If you have been using your computer hard drive for a longer period now and its performance is slower, then upgrading the system on such a hard drive could be riskier for your files lost during the process.
4. Human error: Human errors could majorly contribute to the biggest data loss risk. Any accidentally deleted files or modifications in the BIOS could lead to abrupt data loss. You must read the instructions carefully before upgrading your system.
