Optiplex740 won't boot after installing SATA driver
I came to Dell driver download site and saw the SATA driver nVidia_MediaShield_A08_R181550.exe was listed "urgent" so I download and installed it. The window immediately failed to boot in any mode and went into a loop. I put in window XP installation CD tried to boot from CD but after it loaded from CD it gave me the blue screen of death with code 0x0000007B. I have no way load into window either from HD or CDROM, please help! What did this driver do to my computer?

Hi Robert_tsai,
Please boot to the BIOS and check SATA operation for me. The options are:
Options for mini tower and desktop computers:
NOTE: When in Autodetect mode, the computer configures the drive as RAID if a RAID signature is detected on the drive. Otherwise the drive will be configured as AHCI or ATA.
Options for small form factor computers:

Thank you so much for the help. I see the choice is either RAID ON or RAID OFF and factory default is RAID OFF. I have never touched this and just left it to RAID OFF because I am not familiar with RAID and don't plan to distribute my data to different HD to gain some speed. Shall I choose RAID ON instead?

If your setting was originally RAID off, then you're running in "ATA emulation" mode. Installing the RAID drivers makes the OS look for a RAID drive, which of course, it couldn't find.
There is a registry tweak that will allow you to change to RAID mode, but the difference in performance is minimal.

Hi Osprey4,
I went ahead and played with RAID ON and RAID OFF by first changed it to RAID ON (it had always been on factory default RAID OFF) and to my surprise the window booted up through HD. But it could only boot up when windowXP CD is in CDROM but not booting through CD (ignoring the "type any key to boot from CD" and it will boot to HD after 15 seconds). If I booted from CD then I got blue screen and if I removed CD and tried booting from HD directly it just said no boot device found, so this is not a solution. Finally I went to BIOS and change it back to RAID OFF, magically it now boots to HD without the CD so it appears the problem solved. But I sure like to know why, I have never messed around with that setting (hmmm....may be I will play it more if RAID ON can make HD faster)?
Thank you again for the help, my Dell came back to life now.
Best Regards,
