    HELP: dual-booting W7/8, now Win7 will not load


    Ok, so I've had W8 RP installed since it's second day of availability, and so far I've had zero problems; until now.

    Upon restarting my VAIO, it shows the Windows screen that it shows after you install the RP, it's the loading screen before you choose which OS you want to boot. This screen is now last for probably 5 minutes, and then my screen turns completely off, and then it turns on, but is still completely black, and then it says something like "Automatic repair of drive (D (which is my current W7 drive) and then it, after about 8 total minutes, goes to where you can choose which OS to boot. If I choose 8, everything is fine; if I choose 7, different story. I choose 7, then it gives me the option of Launch automatic repair (recommended) and Start Windows normally. If I choose repair, it shows the background of the auto repair screen, and the mouse appears, but nothing else happens. If I choose Start Windows normally, it shows the W7 loading screen for about 10 seconds, then it goes back to the loading screen before you choose an OS.

    Oh, and what makes it better, is if I'm in 8, and I try to explore, view properties of, or basically anything else dealing with the W7 drive, Windows Explorer (and eventually the Desktop) becomes completely unresponsive, resulting in me having to sign out and back into my PC.

    Please, please, PLEASE HELP.

    UPDATE: after waiting forever after trying to view the properties and contents of the W7 drive, it eventually says something like "D: is not accessible. The parameter is incorrect."

    PLEASE tell me my Win7 isn't completely gone. Seriously. I need those files!

    Try replacing the cable and plugging the HD into a different port. I've had a drive disappear from Windows, and the reason was a bad SATA port on an Asus motherboard. If this doesn't help, try WinPE or maybe an Ubuntu thumb drive installation to get a view of your drives and files.

    Multiple booting is for the birds. I used to be into it heavily, ultimately becoming very familiar with Terabyte's products, but I'll never do it again. Part of the reason is that I now Truecrypt everything, which isn't compatible with it, but if I want to test something, I'll just use a VM. If I really need a real computer running a different OS, I'll use a different computer. And :facepalm: for apparently not having a backup when multiple booting a beta OS.

    Aside: Since you are using multiple drives, it's worth mentioning that installing Windows has been dangerous in the presence of multiple drives ever since Vista with integrated SP1 came out, and I don't know if Microsoft has fixed this in Windows HE. I reported the bug using the channels available to me at the time and also early in the Windows 7 beta. Many months after Windows 7 was released, and a couple of years after I reported the bug, Microsoft finally documented things in this KB article:

    The disk drive numbers may not correspond as expected to the SATA channel numbers when you set up Windows Vista, Windows Server 2008, Windows Server 2008 R2, or Windows 7 on a computer that has multiple SATA or RAID disks
    When you set up Windows Vista, Windows Server 2008, Windows Server 2008 R2, or Windows 7 on a computer that has multiple hard disks, you may experience this problem. Because you expect the disk assignment numbers to match the corresponding SATA or RAID channel numbers, you may set up Windows Vista, Windows Server 2008, Windows Server 2008 R2, or Windows 7 on the wrong drive, or you may even try to format the incorrect drive partition. Therefore, you may lose important data.

    Of course, Microsoft's "resolution" is crap. To be safe, you should disconnect all but the target drive when you install Windows. I thought that was beyond ridiculous. Microsoft did not. They said it would require a "design change" to fix, and so would not be fixed. The funny thing is, the same computer using the same drives connected in the same way had no problems with the original Vista or Windows XP before it, so clearly Microsoft broke something.

    D:\ is not accessible. The parameter is incorrect. (Error)

    in 8,
    Win+X > Computer Management > Storage > Disk Management(Local)

    Check the status of your drives
    Is the W7 drive listed and healthy

    If yes, you could right-click on the drive,
    select Change Drive Letter and Paths
    Change Drive Letter
    reboot

    Ok, so my VAIO is a laptop, and I'm definitely not comfortable taking it apart (desktop I wouldn't mind). So, can you tell me how to view my files with PE or thumb drive? Also, this is not two separate HDs, it's one with two different partitions.

    Mdmd - I'll try that and let you know the status.

    Thanks to both of you.

    I've attached a picture of my disk management. Win7 = D:. Why is the file type changed from NTFS to RAW and why does it say it's 100% free? Please tell me it's not all gone. Please.

    Why it changed is very technical > "the OS has found inconsistencies"
    Your data may still all be there.

    Do not convert to NTFS before using recovery software.

    You will need to search online for a data recovery program.
    I have recovered data from deleted and formatted partitions with special software.
    If you can, search for "recover data from RAW file system"

    First and simplest thing to try is to run chkdsk on the drive showing as raw.

    Try it from within windows 8 to start with.

    chkdsk is a good idea. (with the right switches)
    It can diagnose and fix stuff.
    good.

    Unfortunately,
    This is a more difficult problem because the drive has been converted
    and is inaccessible.

    D: is not accessible. The parameter is incorrect

    If chkdsk does not do the job ( win8 chkdsk might not but it is worth a try), try file recovery freeware Recuva - Undelete, Unerase, File and Disk Recovery - Free Download.


    Minitool partition recovery will almost certainly do it - after quick scan, tick ALL partitions you want to keep, ok, apply

    Free Partition Recovery Software, Deleted Partition Recovery, Hard Disk Recovery, Free Disk Partition Recovery, Active Partition Recovery Software, NTFS Partition Recovery, Recovery Partition, Drive Partition Recovery, Hard Drive Partition Recovery T
