I got this new laptop from Lenovo, a u410 with windows 8. I wanted to downgrade the OS but the problem is it seem that the bios is the slic 2.01 version and I dont know what to do with that. I installed enterprise and the KMS activation fail and says that after 10 attemps that I should try later. (WOAT) When I try with the toolkit and the EZ-Activator, it says it will be impossible to activate via KMS due to OEM BIOS issues. I tryed With WOAT and the toolkit and no chance. Any leads on what I can do ?
