Windows 7: Missing Bootmgr

Missing Bootmgr

So this all started yesterday, I'm running a Windows 7 64bit os on a gigabyte motherboard that is using the uefi dual bios setup. I was clearing some files and my pc crashed, rebooted to missing bootmgr. Grabbed my phone and started to read about it, tried to boot the computer using every option on it, since I know there was 100mb partitioned on it for system recovery issues. System still wouldn't work. So today I downloaded EasyRE and ran that as my boot option off my dvdrom. Now the EasyRE program doesn't launch like neosmart says it should. It leads me to an error: failure reading sector 0x1f9b8 from "hd111". The it goes into grub rescue and that's where I don't know what to do from there. Any help would be much appreciated. It's leading me to believe that my hd is corrupt or completely not working.

If you are not dual-booting a version of Linux I'd be real careful of Grub, could cause more problems. Did you make the Repair disc? It's bootable and can help get you back up. If you didn't, do you know someone with the same version of Win7 that you could get the disc from/made? It has to be from the same version as what you have installed, each version is either 32-bit or 64-bit, your System Specs shows 64-bit. The several versions of Win7 are shown on Windows 7 editions - Wikipedia, the free encyclopedia .

If you have another machine available to you, I would suggest downloading the ISO and burning the standalone boot CD for Partition Wizard.

Even if your hard drive is kaput on the problem machine, you should still be able to boot from this CD as long as the machine itself is still viable. Partition Wizard (PW) running from the CD can tell you if your internal hard drive is actually still operational and visible, and if the partitions are still there as they should be.

Assuming it's a standard Windows 7 install, and assuming the drive itself is still operating and visible, it probably should look like a small (100MB or so) "system reserved" partition that should be indicated as "active" by PW. This is where Boot Manager would be expected to reside. And then there should be at least a second large partition where Windows itself is placed.

You can also use PW's "explore partition" function, to look inside each partition to show folders/files. This will reveal if there is still the expected usable content in each of your partitions, or if they've somehow gotten wiped (i.e. perhaps the NTFS file system is gone or corrupt).

Until you see what PW shows for that drive we can't really talk about what to do next. If it's something as simple as the "active" flag somehow now missing from "system reserved", well that's easy for PW to repair. But if there's more to the story (and possible damage), your recourse would be different.

Anyway, if you can run PW from the standalone boot CD, tell us what it shows for your internal hard drive.

I did use and created the cd for EasyRE, and that's what actually got me to the grub rescue. I'll try what's been posted in the page for the other program. Thanks for the help, but I will be abit before I can get the ISO for the computer since I'm in a small town and most people now have windows 8.

So some good news possibly, I reburnt the EasyRE onto a new cd. When I boot the computer I got a menu for easy essentials, safe or vga. I'm running the essentials now, will update after its done.

You can use any system to download the ISO and burn it to CD. Doesn't matter what the burning system is, as long as you can burn the CD from the downloaded ISO.

And actually, the PW bootable CD is a Linux system disk, although that too is irrelevant. We just want to run PW from its standalone boot CD (so that your inability to boot Win7 from the internal hard drive is not an issue), and see what it says about your internal hard drive on the problem machine.

If you can take a camera photo of your screen and post that JPG, so long as it's large enough and clear enough for us to read, that would be great. A picture's worth 1000 words.

That EasyRE is an amped up version of the Win7 Repair CD, with special abilities: Easy Recovery Essentials | Windows Recovery and Repair CD Downloads

However first you should check that the Hard Drive is detected in BIOS setup. If not you'll need to change cable or reseat it until it shows up, or replace it.

Otherwise everything else that can be done is here for Troubleshooting Windows 7 Failure to Start.
A way to replace the registry with its backup which is automated by EasyRE is in Step 10.

Small update, I've gotten the EasyRE program to launch properly, I had to disconnect my secondary 1tb HD. After a reboot the program properly booted up and I'm in the process of a memory test, then a restore.
