I've purchased a U410 4376 2BU. Recently while Windows was booting it suddenly stopped and I turned off the laptop. Then Windows never started again.

I'm managed to boot from a USB drive with the Windows 7 DVD inside and it doesn't recognize any of the previous windows installations.

My BIOS is set to RAID (from factory), but the RAID controllers (downloaded from Intel webpage as .zip files) still don´t recognize any partition nor windows installation.

I looked into the BIOS and discovered that is UEFI enabled.

have you booted the Win7 DVD in UEFI mode? –  magicandre1981 Aug 18 '13 at 18:41
