From Usb — Installing Os

| Problem | Likely Solution | |------------------------------------------|----------------| | Computer boots to existing OS (ignores USB) | Change boot order in BIOS, disable Fast Boot, enable Legacy Boot if needed. | | “No bootable device” / Black screen | USB not prepared correctly – rewrite using Rufus in DD mode (for Linux ISOs) or ensure ISO is hybrid. | | Windows installation can’t find drive | Load storage drivers from USB, or disable Intel RST/VMD in BIOS (switch to AHCI). | | USB not recognized in boot menu | Try a different USB port (USB 2.0 often works better), recreate the bootable USB. | | Secure Boot prevents booting | Temporarily disable Secure Boot in BIOS (re-enable after installation for Windows 11). |
