I have a Gigabyte ga-ma790x-ud4p MB that I just update the bios to F9 (Add CPU Core Control option) ( update Raid\AHCI ROM ). It completed and I rebooted. My harddrive then disappeared would not boot but DOES show up in bios. I ran recovery it stated at first i need to format first before i can use this drive. I ran recovery again using different option it stated boot sector is corrupt. It showed the data like in a defragmenter program but does not allow me to access it... ??
My plan was since I am going to buy a Phenom II 965 that I needed to update cpu code from F5 bios before I got rid of my current cpu. Then I was planning on setting up my two harddrives in raid 0 installing vista pro 64 bit.
Could this bios flash messed up my harddrive.. ?? It is the only thing that makes sense at this point... ??
I had the SAME problem 1 year ago.The BOOT SECTOR can disappear for no reason sometimes and that sucks I know.Anyway to solve your problem WITHOUT losing ANY of your data,Windows OS and settings,do the following:
-Plug the formatted USB HDD in your computer.The USB HDD MUST be the same or bigger size then the HDD inside of your copmputer
-Boot from the Ubuntu 9.04 CD and choose the first option called "Try Ubuntu without any change to your computer"
-After the CD has booted up and you see the Ubuntu desktop,go to "Places"->"Computer" and then go into your computer's HDD which won't boot.In it select ALL the items and then right click on any of them and then click "Cut"
-Now go back and enter into the USB HDD.In it create the new folder and call it "CLONE".Now go into that folder "CLONE" and there right click with your mouse and click "Paste"
-The MOVING process will start and it can take a very long time so let it finish!
-After the MOVING process is finished,close the window,then shut down the Ubuntu by going on "Live session user"->"Shutdown"->"Shutdown"
-After the Ubuntu is almost shutted down,its CD is automatically ejected.So take out that Ubuntu CD and press the Enter button on your keyboard and the computer will shut down.Leave it like that for about 1 minute...After one minute,UNPLUG YOUR USB HDD!
-Now turn on your computer,open the CD/DVD-ROM tray and put in the EXACTLY SAME WINDOWS XP CD WITH WHICH YOU HAVE INSTALLED YOUR WINDOWS XP BEFORE!!!If its not Windows XP then put in the EXACTLY SAME CD OR DVD FROM WHICH YOU HAVE INSTALLED YOUR WINDOWS OS BEFORE!
-Now go into the BIOS and set your CD/DVD-ROM drive to be the first device to boot from and set your computer's HDD to be the second device to boot from.Save BIOS changes and restart your computer...
-The Windows CD or DVD will start booting.When you get to the screen with the partitions on your computer's HDD,delete ALL the partitions,create just ONE partition that uses the entire HDD and install Windows OS on it.By the way if the OS is Windows XP then for the format choose the option called "Format the partition using the NTFS file system"!
-After the format process is complete and after you have FULLY installed Windows operating system,DO NOT INSTALL ANYTHING NOW!Just take out your Windows OS CD or DVD,put in the Ubuntu 9.04 CD again and shut down your computer!!!
-After your computer has shutted down,plug that USB HDD in your computer again,turn on your computer and again boot from that Ubuntu CD just like before.Again of course choose the first option called "Try Ubuntu without any change to your computer".When the Ubuntu is fully booted up and when you see the Ubuntu desktop,again go to "Places"->"Computer",then go into your computers's HDD.In it select all the items and right click on any of them and then click "Move to Trash"->"Delete All".After all the items are deleted,go back and then go into your USB HDD,then go into that folder called "CLONE" and in it choose all the items and right click on any of them with your right mouse click and then click "Copy".Now go back and again go back and enter into your computer's HDD again and in it go right mouse click and click "Paste" button.
-The copying process has started and it can take a very long time so let it finish!!!
-After the copying process is finished,close the window,then shut down the Ubuntu by going on "Live session user"->"Shutdown"->"Shutdown"
-After the Ubuntu is almost shutted down,its CD is automatically ejected.So take out that Ubuntu CD and press the Enter button on your keyboard and the computer will shut down.
-After your computer has shutted down,UNPLUG THE USB HDD,turn on your computer and VIOLA!Windows boots up again
Cheers!
