Preventing Boot Failure with UEFI Settings
| UEFI Setting | Description |
|---|---|
| Secure Boot | A security feature that prevents unauthorized operating systems from booting. Disable this if you are having trouble booting Windows 7. |
| Legacy Support | Enabling legacy support allows the system to boot using traditional BIOS instead of UEFI. Useful if Windows 7 was installed in legacy mode. |
| Fast Boot | When enabled, the system skips certain initialization steps to decrease boot time. Disable this if you are experiencing boot issues as it may cause conflicts. |
| CSM (Compatibility Support Module) | Similar to Legacy Support, enabling CSM allows the system to boot using BIOS instead of UEFI. This may be necessary if Windows 7 was installed in legacy mode or if you have incompatible hardware. |
| Boot Order | Specify the order in which devices are checked for bootable media. Ensure that the primary boot device is set to the correct Windows 7 installation source. |
| UEFI Firmware Settings | Access the UEFI firmware settings to make changes to the boot configuration. This is usually done by pressing a specific key during system startup, such as F2 or Del. |
