The Salt BIOS setting usually does not delete files; however, the boot mode, disk controller, TPM Clear or incorrect installation procedures may affect Windows access and encryption keys.
Secure Boot, TPM, BIOS updates, and some firmware changes can change the security measurement and Windows may request a recovery key at startup.
Manufacturers may offer the same feature under different menu names and locations. The exact step must be verified based on the device's full model and BIOS version.
Normal firmware menu usage usually does not void the warranty; opening the case, physical CMOS intervention, or unauthorized firmware operation may affect the manufacturer's conditions.
No. It is more correct to not add unnecessary risk to a working system unless there is a security, hardware compatibility, or manufacturer's stated issue.
Universal password or bypass should not be used. Manufacturer support or the company's IT manager should be used with device ownership proof.
No. Firmware recovery, physical CMOS, disk failure, and data recovery operations require model guide and, if necessary, authorized service.
We safely examine Windows 10/11, Secure Boot, TPM, SSD detection, USB boot and firmware recovery problems according to device model.
