1. Creating bootable USB via a free Fufus software.
- Device: rufus will detect your usb stick automatically.
- Boot selection: select the operating system image file (iso,...).
- Partition scheme: GPT (I recommand use GPT because it has more advanctage than MBR).
- Target system: UEFI.
- Volume label: (lel keep as default).
- File System: NTFS.
- Cluster size: (keep default).
- Click Start: (Note: your data on USB will be erased).
2. installing Windows
To boot to UEFI or BIOS- Insert bootable USB and press power boot botton then press keys: Esc, Delete, F1, F2, F10, F11, or F12. On tablets, common buttons are Volume up or Volume down. Note: you can see the key shortcut for entering cmos during starup computer.
