    No boot after extending partition


    Hi,
    I just recently installed windows 7 on a partition that previously had vista, and backed up my "users" folder on another partition. I copied all the files back to the 7 partition and used a program like partition magic to delete the backup and extend the 7 partition. my computer won't boot now. I've tried resetting the mbr, bcdedit, bootfix, and pretty much every solution on the first 20 pages of a google search about this. Help!?

    You probably deleted the hidden 100 Mb partition holding the boot files. If you dual booted they were in the vista partition

    If you have you win 7 dvd (not a restore dvd) you can do a repair install, by booting from the dvd.

    A screenshot from disk management using the snipping tool would help.
    Use the paperclip or manage attachments.

    I have a copy of Active@ Boot Disk, which is the only way i can get good info from the system. This is a screen shot of the partitions.
    If you look, there is a ~150GB drive which according to the partition manager, is a 7GB and a 140GB partition. The 140 came from extending a 70 to another 70. If you look to the left, you can see a Local Disk #0. This is the old vista partition, but I have no clue how it exists as it does now.

    Even more crazy to me is that my "new" 140GB partition says it only has a capacity of 70....

    If you need any more info let me know, I really appreciate it

    Partition Magic will mess up your Win7. Use free Partition Wizard bootable CD. Free Download Magic Partition Manager Software - Partition Wizard Online

    It appears the System MBR has been compromised and needs repair. Since it is already marked Active, boot the Win7 DVD Repair console or Repair CD, accept any offered repair. If it doesn't start, boot back in to run Startup Repair from the tools list up to 3 separate times with reboots so it can attempt repair and possibly rewrite the System MBR. Startup Repair - Run 3 Separate Times

    If this fails, boot Partition Wizard CD: Confirm Win7 partition is marked Active. On the Disk tab, try to Rebuild MBR. If necessary post back a screenshot of PW drive map with listings.

    More questions than answers.
    Looks like the HDD shown (Acer Vista PC?) originally with PQservice (factory recovery partition), a system reserved now unallocated, Originally a Vista OS partition (70GB0, and a data partition (70GB). Is that the way it was?

    What Windows 7 install disks have you got?

    Edit: Just seen the response above. Information from/ and using Partition Wizard would be useful. You've still got some unallocated space sandwiched in there.
    I don't think Startup repair will help since you say you've done the manual equivalents. But give it a go.

    Hello nnate72, welcome to Seven Forums!



    For future info; there is a way to boot the Windows 7 installer to diskpart to see information about the Hard Disk Drive(s) attached to the PC, you would use commands like these once in diskpart, for instance, to see if a partition/volume is marked "Active" when finished type exit twice to get back to the installer; have a look at these two tutorials below.

    DISKPART : At PC Startup

    SSD / HDD : Optimize for Windows Reinstallation


    list disk <enter>
    select disk # <-- the targer disk #
    list partition
    select partition #
    detail partition

    list disk
    select disk #
    list voume
    select volume #
    detail volume

    Alright, well I can't post a screen of the computer because it is just booted to Partition Wizard (which I now remember is the program that I originally modified the partitions with), but I can describe the information. I also did try the 3x Startup repair...no go. I have also detailed the disk in diskpart (see screen above).

    Disk 1 is listed with:
    *.PQSERVICE - FS=NTFS| CAP=7.81GB | USED= 5.81 | STATUS=NONE | TYPE=PRIMARY |
    *.- FS=NTFS| CAP=70.47GB | USED= 49.25 | STATUS=ACTIVE | TYPE=PRIMARY |

    *. Properties: Type ID= 0x7 | FS=NTFS | S/N={some numbers} | First Physical Sector=16371712 | Last Physical Sector= 312576704 | Total Physical Sector=141.24GB


    If I click on recover partitions, I find that there is a Lost/Deleted partition (the old vista one). I cannot recover it however without deleting the new partition though because they overlap.

    I tried choosing "Set windows boot partition" but the response is "no windows directory."

    There is a windows directory though.... three in fact (all created by startup repair):
    Windows\
    Windows.old\
    Windows.old0\

    The only thing I can think of is finding out what command Partition Wizard used extend the partition, and then reverse that. Either that, or wait a week or so until I have access to an external HD so that I can back up the files and then just clean install.

    Any ideas?
    Thanks again.

    Did you run Rebuild MBR from PW Disk tab as suggested earlier?

    Does an OS show to repair when you boot into Repair? What is the exact result given after running Startup Repair three separate times?

    Try to copy out your files with DVD/Repair CD using this method if they were not properly backed up: Copy & Paste - in Windows Recovery Console

    Then wipe the HD to clean reinstall using these tips to get a perfect install: re-install windows 7

    Ah yes, I did try to fix MBR as well with PW, sorry, forgot to mention that.
    When I boot to repair, it says "nothing wrong was found" every time.

    I can't copy my data over to another HD, as I have none (until next week).
    Why does it say that there is no 'windows' directory? Any other thoughts?
