I don't know, I asked the same question because there were many people in this thread who had problems after installing the unlocked bios ver 8.xx. I think it could be safe to install the unlocked bios ver 8.00 not 8.01. Can someone confirm that?

The solution is few posts back: http://forum.techinferno.com/lenovo-ibm/2260-lenovo-y580-y480-unlocked-bios-versions.html#post69650

I wanted to confirm that this does remove the SecureBoot watermark from Windows 8.1. I upgraded from v2.07 to the beta BIOS.

The only other issue is that in the BIOS, it says that the Windows license is invalid.

I wanted to confirm that upgrading from v2.07 to the beta build posted in #859 works. It eliminates the 'SecureBoot isn't configured properly' watermark in Windows 8.1.

The only other minor issue is that in BIOS, the Windows License is invalid. Not sure how to rectify this issue.
