100gigs is most like the recovery partition. If it's anything like other mainstream laptops it's got a tools partition also.
If you go with a recovery just open the program list and select recovery manager. Follow the prompts.
BTW did you really give $2799.00usd dollars for that thing? MSI Global ? Notebook & Tablet - GT70 Dragon Edition
Thanks. so now i have restored it and i guess only time wil tell if it worked
For the GT70 i got, i paid between 2000-2100 USD approxemetly, since i didnt pay in USD, i did it in Dkr.
