The PC skips the Windows USB installer

Open the one-time boot menu and select your Windows USB.

1. Recreate the USB if missing; match Rufus GPT/UEFI settings to your boot mode.
2. Try another USB port, including USB 2.0 on older boards.
3. Check Fast Boot if it skips the boot-menu prompt or USB initialization.

DiskPart reports write protection

Check for a physical lock, then use an administrator terminal to clear the correct disk's read-only attribute.

2. Try another port or cable.
3. Test on another PC; replace the device if write protection persists.

Secure Boot is missing from the BIOS menu

Check whether your motherboard requires UEFI mode with CSM/Legacy disabled to show Secure Boot.

1. Check Boot, Security and Authentication menus.
2. Some boards require a BIOS administrator password; follow the manual and retain it.
3. Check for a supported BIOS update for your exact model and revision.

TPM is unavailable or not detected

Look under CPU or Security settings for Intel PTT or AMD fTPM.

1. Enable the option matching your CPU and motherboard.
2. Save, shut down and power-cycle if required by the manufacturer.
3. Check BIOS release notes if the option is missing.

There is no display after a BIOS update

Allow the manufacturer's first-boot or recovery process to finish before interrupting it.

1. If instructed by the manual, clear CMOS.
2. Disconnect power as instructed and check RAM/GPU seating.
3. If supported, follow the board's BIOS Flashback procedure.
4. If recovery fails, send the board model and firmware version to support.

A purchase download is missing

Check payment and delivery status in My orders; send the order reference to support if paid files are missing.

The license is not accepted

Copy the full key without spaces, check its product and dates, then send any remaining error to support.

Install or repair the named runtime using the correct architecture, and keep all extracted product files together.
