Missing Boot Manager

    Looks like it might be an EFI installation on GPT disk.

    Maybe the Linux tool you ran corrupted the data as you suspected, so that it is only showing in Recovery Wizard.

    There is a recent thread where a data recovery software was able to recover the data (not partition structure) from a GPT disk. I'll try to find it or maybe someone else will link to it or recall the software.

    Do you have your files backed up elsewhere? Because even if you can recover the data it will likely require a Clean Reinstall.

    I would convert the HD to MBR to reinstall with EFI taken out of the BIOS boot order

    I decided to check out some of the other tools. I loaded up Diskgenius and looked at the partitions on that drive. I don't remember my exact steps but it scanned the drive and said it could write a new partition table (or some such terminology). It found that 100mb partition and it was set to active. It prompted me to save my new partition table. Asked if I wanted to do MBR or GPT. I chose MBR and restarted. Windows recovery started from the DVD and found my installation to repair. It repaired and restarted. Then Windows 7 started from my SATA drive! Everything seems to be intact.

    Great News! What caught your attention about that particular app on Hiren's Boot CD?

    We will have to remember
    DiskGenius 3.2 Restore deleted partition, Rebuild MBR, Rebuild partition table, Recover files, Restore formatted partition, Backup files by partition, Disk clone, Backup partition table, Create/Delete/Format Partitions etc.
    listed under Recovery Tools section.

    Can you post back a Win7 Disk Mgmt screenshot now?

    I decided to give DiskGenius a shot because it mentioned "restore deleted partition" since Partition Wizard seemed to see my deleted/lost partitions but didn't seem to actually do anything about it. Maybe I was doing something wrong.. not sure. And I'd love to post a pic. Because after all is said and done I'd love you to look at my set up and see if it seems "back to normal" as far as a basic Win 7 install should. There is that odd bit of unallocated space but I don't know if it was there before or not. I've never actually used the disk management tools before today.

    Attachment 210959This is really strange. It seems to have jettisoned the EFI partition which comes with an EFI install to GPT disk. The space is there but not the EFI partition, which I noticed was also missing in the PW Partition Recovery Wizard findings.

    I am now wondering if it is still even a GPT disk or was rewritten by DiskGenius as an MBR disk.

    Well. DiskGenius did ask if I wanted to save it as MBR or GPT and I chose MBR. Don't know if it was the right choice but everything seems to be working.

    To find out in Disk Mgmt rightclick on Disk0 box highlighted in screenshot below, then select Properties, then the Volumes tab to see what format is:

    That makes DiskGenius even more of a good find. I've already added it to Troubleshooting Windows 7 Failure to Boot. See if you think I placed it correctly in context for how it might work best as a last resort.

    Nice work there. We all learned, and given the title countless others will find this via Google.

    When ready you can mark the thread Solved at top.

    I think it fits in well where you put it. Thanks for all your suggestions. It's never as easy at it seems (or you want it to be) It was a lot of back and forth, a lot of picking through what works and what doesn't. And I'm sure those more savvy then me might find all the info they need in between my ineptitude.

    I can happily say that not only does it boot but boots faster then it used to, noticeably.

    I may have inadvertently flashed by bios trying something unrelated, but that's another questions for a different thread (or forum?)

    Thanks again to forum member gregrocker
