Intel Rapid Storage Bootloader problem

Hello,

Sorry for my poor English....

I install Intel Rapid Storage on my laptop (ASUS UX303LA) composed of I5 U4210, 1 HHD and 1 SSD (M2 of 32go)

Version installed:

For IvyBridge Sample Item

SW Item : IRST_CacheHidden

Version : 11.6.0.1030

But after a restart my bootload is completly broken.

I can make any restoration,

I  try some CMD command to restore it but without success:

• bootrec.exe /rebuildbcd

=>  say no windows install

• bootrec.exe /fixmbr

=> say ok done

• bootrec.exe /fixboot

=> say ok done

• bootsect /nt60 ALL
  

=> say Harddisk root folder can't be open

• chkdsk /r c:

=> ok no pb

• bcdedit

=> all is ok

• bootsect /nt60 c: /mbr

=> say, you used a different mbr volum partitionning... avoid

Please, have you any solution of my problem without erase all my files?

Thanks for your help,

brodbeni
