[solved] Lenovo Legion y520 issues

[RehabMan]

Hey guys... I'm trying to get HS to boot normally without USB and the issue is, it won't. It will only boot if I use a desktop system definition. When I use another System Def. it will just restart. Any help? please

After a lot of research the problem turned out to be "Unsynchronized TSC" and VoodooTSCSync.kext seems to fix this problem.

@ptcptc The fix is in that Thread, Also A guide made by Abdulilah to get most things working
