    Removed dual booted XP, "Reboot and select proper boot..."


    Hi!
    Alright, so I screwed up big time. I had Windows XP pre-installed (C:) when I bought the computer nearly 3-4 years ago.Then I dually installed Windows 7 to a logical partition (D:), and then experimentally installed Windows 8 Pro WMC (G:) to the last partition, which is currently the default. I needed some space, so I decided to remove Windows XP, and like an idiot, formatted the C: partition with GParted. Now I get the "Reboot and select proper boot device... or insert boot media in selected boot device and press a key" error. I used Windows 7 Repair disk, tried attempting repairs with Windows 8 Pro installation disk, tried changing partition flags (I don't even know what they are), tried a warez disk, but nothing works. Even the Win8 installation disk doesn't show any operating system installed. Also, my HDD is set as first boot priority in BIOS.

    Any help is appreciated!

    I attached a screenshot of my partitions from GParted.

    Thanks in advance!

    P.S. Although it is named Windows Developer Preview, the partition has Wndows 8 Pro WMC in it.

    OS's will not boot from Logical Partitions.
    By deleting the Windows XP partition, you also delete the boot files for Windows 7 & Windows 8.

    Thank you guys for replying! MrShowdown, sda1 used to be XP, sda5 is Win7 and sda8 is Win8. Sda6 and sda 7 are just storage parrtitions.
    And isn't there any way to bring back those boot files, theog?
    I am also about to try some boot managers.........hope they help.......atleast to get in.
    Thanks again!

    EDIT:
    Okay, so I tried the plop boot manager, and I get two options, "HDA Partition 1", and "HDB Partition 2". The former doesn't do anything but bring the screen back to the boot manager. The second one, however, attempts to start but shows the "BootMGR is missing" error. So I think if I am able to write a boot sector to sda2, then maybe it'll work. The question, really, is how. I might also be wrong. Please let me know if there is anything you have. And if this method will work, and how.

    If you convert the Windows 7 & Windows 8 partitions to primary, yes.

    In the screenshot below, the boot files are installed to System Reserved partition.

    Thanks theog. Any ideas on how I can do that without accessing Windows? (Not really that tech savvy )

    The base of what you need to do is in this tutorial:
    Partition : Recover Space Used by an Older OS - Windows 7 Forums
    But you must convert the Windows 7 & Windows 8 partitions to primary first, leaving no more than three partitions.
    When you have Windows 7 booting OK, you can add Windows 8 with EasyBCD.

    There is a how use EasyBCD in this tutorial:

    Your boot flag is currently on SDA8. You could move it to SDA1, the only primary partition on the drive, and then do a startup repair 3 times, or an automatic repair for Windows 8.

    A'right! I tried theog's method. I set Windows7 and Windows 8 to primary partitions, although I couldn't make the XP partition logical. Then I set Windows 7 partition active. I restarted and got the "NTLDR is missing" error. So I booted the Win7 Repair disk and sent the fixmbr, fixboot, and fixbcd commands and chkdsk-ed C: and G: (Windows assigned Win7 to C: and formatted XP partition to F:). Then I did the startup repair. It asked me restart, and on restart, I get a black screen with an underlined cursor blinking. I tried the startup repair 3 - 4 times and it says there isn't anymore error.

    Then I tried it with Win8 installation disk. I attempted repair but no good. One thing i noticed is that the disk gives me three operating systems to go on with, in the order, "windows boot manager", "windows 8 (recovered)", "windows 7 (recovered)". All of them lead to the black screen with the cursor.

    In Plop Boot Manager, HDA Partition 1 gives nothing, HDB Partition 1 takes me to "BootMGR is missing" error (I'm guessing Win8). HDB Partition 2 takes me to the blank screen (Bootloader, maybe?). HDB Partition 4 takes me to "NTLDR is missing" error (Win7). There is no HDB Partition 3 (maybe the XP partition).

    SaltGrass, after doing all of the above, the attached image is the current state. Note that sda1, sda2 and sda4 are primary.

    If there is any way to get past the black screen...

    Please, any help is appreciated. You can see how much data I vulnerable to lose.

    Thanks again!

    The Windows Boot Manager option, you mention, has me a little confused since that is normally an option given for a UEFI installed system. Any comments about that?

    It looks like you have Windows 7, installed on the second partition and it is active. It should be noted, an EFI partition may also show with a Boot flag. When you boot, you say you have a option to a Windows 7 Recovered, and that should be the one you boot to.

    But I think, a single blinking cursor will normally mean the boot is not being sent to the correct place.

    But we need to narrow down the possibilities and concentrate on one OS only, it just confuses things when jumping around. And Windows 7 Startup repair attempts will normally need reboots between tries.

    Edit: Also, if you says NTLDR is missing, the the Master Boot Record is looking for an XP type of boot. If it says Bootmgr is mission, then it is looking for a Windows 7/8 type of boot. I once had to run a Startup Repair 4 times to overcome an XP MBR. You can see how it might work in the link below.
