Using dual boot, I can access my H: (WIN7 boot) drive when I boot to my C: (Win-XP) drive but I cannot boot to Win7 directly. No change in hardware. Been working fine for 2 years.

All previous 'fixes' via DOS (BOOTREC /FIXMBR, BOOTREC /FIXBOOT, BOOTREC /REBUILDBCD, etc...) didn't work. Maybe because I'm not comfortable working within DOS and did something wrong.

Since I can see all Windows 7 files from C: (XP) is there an easier way to do this bypassing DOS?

The Windows 7 errors I experienced in the automatic repair are:

  • Boot Manager failed to find OS Loader.

  • Boot configuration data store repair failed.

  • Boot Manager generic failure.

  • Windows cannot repair this computer automatically.

I do see the file H:\Windows\Boot\DVD\PCAT\BCD and H:\Windows\Boot\PCAT\bootmgr but Access is Denied for editing. Is access to these folders the problem?

These are not magic fixes, each one does a specific thing and you shouldn't run fixes just randomly...

Win7 errors are: Boot Manager failed to find OS Loader. Boot configuration data store repair failed. Boot Manager generic failure. I do see the file H:\Windows\Boot\DVD\PCAT\BCD and H:\Windows\Boot\PCAT\bootmgr but 'Access is Denied' for editing. Is access to these folders the problem?

You seem to have pasted some random errors together, can you tell us when each of them happens?

Have you researched these errors? Which suggested fixes did you try and why didn't they work?

Boot Manager failed to find OS Loader.

This means that the Boot Manager either misses configuration to find the OS Loader or it is missing.

Boot configuration data store repair failed.

This means that an attempt to repair the BCD store has failed, it might be corrupt or inaccesible.

Boot Manager generic failure.

This really depends on what you have been doing, doesn't say much...

I do see files [cut] but get 'Access is Denied' for editing.

Just finding the files on the disk and checking their permissions does not makes sense. Note that Windows actually protects you from tempering with it, they are not meant to be edited. If any, the paths you mentioned are kind of irrelevant; DVD\PCAT means you are looking into the Product Catalog part of the Boot Manager of Installer copied of the DVD.

You could attempt to copy BCD from that to see whether that has any effect to restore your BCD to an original state, which could work; but don't forget to make a back-up first...

You can gain permission using these instructions, make sure that while doing so that you don't remove any permissions. Also make sure to take a back-up of the old BCD folder in case it doesn't work.

Welcome to Super User! This was meant as a teaching point to troubleshooting problems, not to dumb you down. For us to understand what exactly is going on we need as much information as possible / reasonable, to give you a random example: If I paste 0x8007005 would you be able to tell exactly what I was doing? Well, yeah, it's an Access Denied but that doesn't tell me what access is being denied. If I were concise, I would've said "I'm missing information"; but without pointing out which information we don't get your problem solved. Could you please try again? I've edited first part... :) –  Tom Wijsman Feb 12 '12 at 0:03
    
"Failed to find OS Loader" and "Boot configuration data Store repair failed" were both in the detail of 'Windows cannot repair this computer automatically'. <<You could attempt to copy BCD from that..>> from where? the installer DVD? I won't be able to copy it over the existing because of no write permission. Need to do this in DOS? Thank for quick reply. Projects due Monday. –  Steve Hix Feb 12 '12 at 0:07

@SteveHix: Ah, the automatic repair, thank you. Seems it is corrupted missing. You can gain permission using these instructions, make sure that while doing so that you don't remove any permissions. Also make sure to take a back-up of the old BCD folder in case it doesn't work. I meant from the first file path you mentioned, but it could also work copying it from the installer medium. Good luck! :) –  Tom Wijsman Feb 12 '12 at 0:13

That's what I'll do. For some reason I WAS able to boot to H: Win7 just now, but I'm replacing the HD anyway. Thanks for all your help. –  Steve Hix Feb 13 '12 at 22:14
