    unable to install windows 7 64 bit after replacing with multiple OSs


    My laptop came preinstalled with win 7. anyways I was trying to install ubuntu 13.04 on it and unfortunately I ended up replacing it with ubuntu. Later on I found ubuntu to be almost unusable and instead replaced it with windows 8 32 bit because I couldn't find my win 7 setup disc. Win 8 sucked so after a week I tried to install win 7 on top of it but there was error everytime along the lines of : " windows doesn't support your hardware". After some searching on the net I found something about how win 8 uses GPT formatting on the drives and win 7 uses NTFs and win 7 can't really work on GPT.
    So once again I installed ubuntu wiping win 8 and reinstalled win 7 . I got the menu and everything, repartioned the drive (effectively butchering ubuntu) formatted and installed win 7 on a 150 GB partition. Again the installation got all the way to "finishing installation" when I get the incompatible hardware error. What's wrong? Any help will be appreciated. And yes this is my first time installing OSs. Gotta beging somewhere right? Any help will be appreciated. Thanks. :)

    Unplug all other HD's and peripherals,

    Boot into BIOS setup, reset to defaults, save changes. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

    Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

    At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

    DISKPART
    LIST DISK
    SELECT DISK 0 (after confirming Windows 7 target HD #)
    CLEAN
    CREATE PARTITION PRIMARY
    FORMAT FS=NTFS LABEL="WINDOWS 7"
    ACTIVE
    EXIT
    EXIT

    Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

    In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

    After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

    Thanks for your replies !!

    I've started doing as you ask gregrocker. I don't have any os installed on my laptop at this point. Also I am unable to change SATA settings from bios. So I did the rest and am currently formatting the HD to NTFS . Its taking quite a vit of time. 7 percent in 15 minutes. I will update when it is done

    What is the current SATA controller mode in BIOS setup? Why is it you can't change it? Did you see the written directions on the BIOS page?

    What's most important is to Clean the HDD. But formatting a partition to mark Active also solves other problems. If format is slow it could be bad sectors being quarantined, or a failing HD. Have you checked its condition lately?

    You may need to confirm your HD condition using the maker's HD Diagnostic extended CD scan, or run Partition Wizard CD HD surface test, followed by Disk Check run on the partition you created from the booted Win7 installer command line.

    There is no SAtA option in BIOS. No tab or option in submenus I checked.
    Failing HD? It seemed to work just fine in win 8.

    OK then one of the steps given should help. They solve most installation issues. If not report back the exact failure, any verbatim error and at which step in Clean Install Windows 7

    Ojay so the format just finished and I've started installing win 7 64 bit. :fingers crossed: also it seems that the primary partition has only 700 gigs of space. My harddisk is 750.

    Did you mark the Partition Active?

    The formatting takes up some space, but as stated you could have had bad sectors quarantined which is why it took so long.

    If it installs after getting online, enabling Automatically deliver drivers via Windows Update (Step 3)
    while it is running all rounds of Important and Optional Windows Updates (with reboots) until there are no more offered, I would install CrystalDiskInfo - Software to read the HD's status.

    If install fails I'd run the diagnostics and Disk Check from the links posted in #5.
