General failure with Allienrespawn on Allienware m17x-R4

It's a long story and I am hopeless now,so please help me,much appreciated....

At first ,i encountered some serious delay on plug-in internet connection with my Allienware m17x..

Then after searching for every solutions,it didnt help to resolve it,so I decide to use Allienrespawn to recover.

As usual,after log in and select the Factory Image from Allienrespawn,my Laptop as for: preserve private document or not - selections....I chose the Yes one,and the process was frozen...

I had to hard reset by power button,and it got stuck just after the allien logo appearance...

Then I read some article,trying to re intall windows 8 via the Dvd came along with my lap.

And when the intall process come,it didnt recognize any HDD:((

Then after some more reading,I went to Bios setting,found out that the setting was RAID ,and my lap come with single HDD,so i switched to AHCI,and then,the install process recognize imy hdd again.

After re intalling,I tried to install Allierespawn once more...

Because i really wanna put my laptop to factory settings>.<

Then after that,allienrespawn still recognize the factory image partition in my lap but it cant recover from it,just after i choose the partition,it asks for restarting,and just boot derictly to windows 8...

I dont know what to do now.Plz help!
