## Issues Related to PXE Boot

1. ### Unable to boot the machine from PXE

   Get the error codes and send them to our technical support (osdeployer-support@manageengine.com) to track the issue.

2. ### There is an unexpected failure while booting the machine from PXE

   Ensure that the ManageEngine [PXE](https://www.manageengine.com/products/os-deployer/help/bootable-media/pxe-preboot-execution-environment.html) Server is started. If you are unable to start it, then try restarting the ManageEngine OS Deployer OS Deploy Server.

3. ### PXE Boot cannot find any NIC

   This may occur when the issue is possibly with the bootable components. Try using the Bootable Media to boot the machine.

4. ### PXE Boot cannot find any find HDD

   If the SATA operation mode is set to RAID, then switch to AHCI or IDE.

5. ### ManageEngine Loader Fatal Error

   This error indicates that at least 512 kb of conventional memory is required. In the computer BIOS, change the SATA operation mode from RAID to any other mode. As a workaround, you can also use Bootable Media to boot the machine instead of ManageEngine PXE Server.
