System Recovery Options - no operating system listed, need to load the drivers, but don't know where to find this (Windows Vista 64-bit)

It is a gateway M6866 laptop running Windows Vista 64-bit.

The computer does not start up--gives "BOOTMRG is missing" error at startup.  I'm trying to boot from the 64-bit of Windows Vista recovery disc.  I clicked on the "repair your computer" option, and it shows the computer loading files.  Then the "System Recovery Options" box appears and asks me to select the operating system to fix it.  The problem is that nothing has listed.  It is said that if your OS is not listed click Load Drivers.  I did, but it is said to insert the device installation media, and then click OK to select the driver.  I clicked on OK and then opens a browser window to select the file.

I don't know which file I'm supposed to select here.  I searched online for an answer, and someone told him to go to the computer manufacturer's website and download the driver for RAID controller.  I tried to go to the site of the bridge to find it, but it doesn't seem to be one for Vista 64-bit.

Please please help!  I have to at least be able to extract the files to the hard drive before reinstalling windows.

Hello

·        Have you Configure RAID on the system?

If you have not configured then RAID on the system, I suggest you to disable the RAID/eSATA (SATA improved) in the BIOS. Once you turn off the RAID/eSATA on the system that your basic hard disk should be recognized by the system because it doesn't require any drivers, it will act as an IDE. Once you have disabled the RAID/eSATA then booting into the recovery environment and build the Bootrec and check if the problem is resolved. I suggest you follow the steps mentioned below to rebuild the bootrec.

Rebuild the BCD store by using the Bootrec.exe tool in the Windows recovery environment. To do this, follow these steps:

a. get the Vista installation DVD and pop in your drive.

b. then restart your computer.

c. press a key when you are prompted.

d. Select a language, a time, a currency, and a keyboard or another input method, and then hitNext

e. click on repair your computer

f. click the operating system you want to repair, and then click Next

g. in the System Recovery Options dialog box, click command prompt

h. type bootrec /rebuildbcd and then press the Enter"" key.

·        If Bootrec runs successfully, it will present you with the installation of a Windows directory path. To add the entry in the BCD store, type Yes. A confirmation message appears that indicates the entry has been added successfully.

·        If Bootrec cannot findany lack of facilities of Windows, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order shown below: (remember to press ENTER after each command)
bcdedit/export C:\BCD_Backup
Ren c:\boot\bcd BCD.old
Bootrec /rebuildbcd

i. restart the computer.
