Hi folks.
Many of you are experiencing a known issue when attempting to install the Windows 8 RP on the Samsung Build PC. I myself ran into this issue. The symptom when attempting to install the latest release is that the BIOS will report "Invalid Signature
Detected". The reason why you see this is that the Windows 8 RP build is signed a little different than the previous Consumer Previous build.
There are several workarounds for this, specifically you can turn off Secure Boot in the BIOS. Once you disable it, and install the Windows 8 RP build, if you re-enable Secure Boot, you'll notice that BIOS blocks the Windows 8 loader. This is
by design, although problematic.
The way to resolve this is to take the following steps:
1. Enter into BIOS (press Volume UP & Down as you power on)
2. Go into Advanced Menu
3. Disable Secure Boot (leave CSM disabled to ensure that Windows 8 installs in UEFI mode)
4. Reboot with Windows 8 RP on a USB Fat32 formatted USB device, install Windows 8
5. After you're done installing Windows 8, visit the Samsung site to install BIOS Rev. 05WJ on the Samsung Support page (http://www.samsung.com/global/buildpc/)
6. Download #3 is the BIOS update that you can launch from Windows 8 after you complete installation
After your BIOS is updated, Secure boot will be re-enabled and everything is set to go! This does not impact device drivers, and your OS will work just fine.
TIP: Do not enable BitLocker until your BIOS is updated. If you have BitLocker enabled, make sure you disable it during the BIOS update.
