If not, try a different USB 3.0 port. | | Installation hangs at “Starting Windows” | Missing graphics or storage driver | Boot with CSM enabled; try a different SATA mode (AHCI, not RAID). | | “Missing media driver” popup | Tool didn’t inject drivers properly | Redo with ISO mode → use Rufus to write ISO, then manually load drivers from USB during setup. | | Setup cannot install on GPT drive | BIOS in UEFI mode, but USB made for MBR | Recreate USB with ISO mode + Rufus set to “GPT for UEFI.” |
