Installing Windows usually requires a USB flash drive or DVD, but you can actually perform a clean installation directly from your computer's internal hard drive. This method is a lifesaver if you don't have a spare thumb drive or if your USB ports are malfunctioning.
Safer and simpler – use a secondary internal drive as the installation source. how to install windows from hard drive
| Mistake | Consequence | |---------|-------------| | Installing Windows to the same partition containing setup files | Setup will fail or become corrupted | | Forgetting to mark partition as active (Legacy BIOS) | System will not boot into setup | | Using NTFS on a UEFI system | UEFI cannot boot from NTFS (use FAT32) | | Deleting the setup partition after installation | Unused space – safe to delete later via Disk Management | Installing Windows usually requires a USB flash drive
