Thanks for replying guys but the problem is I cant enter into safe mode. I already tried that hoping I can just do a system restore. When i try to enter safe mode the same thing happens & the system just crashes. In fact I can't enter Windows at all. Yup, I did have Bit Defender Total Security on while I was downloading the update. But I monitored it and there appeared to be no glitch during the download & installation. I contacted ASUS and they said:
"This is due to the language packs in our RCD have other languages, which is different from the 5 languages (English, French, German, Japanese and Spanish), which SP1 released.
There are 2 ways to avoid this, you need to
1. Install OS with English only (or with the other 4 languages OS) + SP1 (5 languages package).
2. Or the Original RCD OS + SP1 (all-language package)."
But my main concern is how to rescue my important files in my laptop. I know the options they gave as well as the options presented in the rescue disc will to re-install the OS but will also delete my files in the process. I'm afraid that if I open up my laptop & back-up the hard drive as a slave to another computer will void my warranty since the unit is still a few months old. How do I resolve this???
