Blew fuse at home, Windows won't boot, HDD "inaccessible"

Where is the screenshot?

We need to see if Win7 has its own System Active boot files, because so far it will only boot from the old Win7 when that is set first to boot - meaning that it is booting off those boot files and not it's own.

If it has it's own boot files then they may need repair. Did you try the bootrec commands to repair or rebuild the boot, or at least make the installation visible to Startup Repair to do so?

Here it is:

Only thing I tried is that auto boot repair using install CD and the chkdsk /r command, nothing more. Like I mentioned, drive appears to be fine. C is my new one that I can't boot with and H is the old one that's for some reason booting Windows from new HDD.

As suspected C does not have its boot files so is booting off SysReserved on Disk0, as signfied by the System flag being there.

To remedy this, Mark C Partition Active and then Mark D Partition Inactive.

Then power down to unplug DIsk1. Next unplug Disk0 (H) and swap its data cable to Disk2 (C) so that it is in first slot where it cannot have its boot derailed in the future. Make sure it remains set to boot first in BIOS setup, after disk drive.

Now boot into Win7 installer System Recovery Options or System Repair Disk to run Startup Repair - Run 3 Separate Times until C becomes marked System Active and boots on its own. If necessary make a new Repair CD: System Repair Disc - Create

You can now plug back in the old Win7 HD if desired, when needed boot it by tapping the one-time BIOS Boot Menu key at boot, choosing it there only. If it persists with the Dual Boot menu, enter msconfig>Boot to highlight and delete the other listing.

Well I marked C as Active and D as inactive, but startup CD won't repair now, says that ot can't, asks to remove any new hardware. If I try booting from new HDD it says boot manager is missing and ctrl-alt-delete to restart.

You have to write the System boot files to C first. Mark C Active, unplug all other HD's, run Startup Repair up to 3 separate times no matter what it reports until Win7 starts on its own.

If it fails it is likely due to corruption of the boot files which Win 7 cannot repair. You can either continue to boot it from the old HD by setting that first to boot in BIOS setup with only SysReserved marked Active,

or shrink C by 200mb in Disk Mgmt or using free Partition Wizard bootable CD to create a Primary NTFS partition marked Active and labeled System Reserved, then with all other HD"s unplugged run the three repairs to write the System boot files to it to see if that works. You are creating a new boot partition there to replace the corrupted boot files on C.

Unplugged all HDDs, but recovery still tells me that it's not possible to fix the problem or that it's version is not compatible with the version of windows if I let it detect Windows itself.

Then burn another Repair CD as suggested earlier. System Repair Disc - Create

Or burn the latest official installer for your licensed version from Step 1 and 2 in Clean Reinstall - Factory OEM Windows 7.

You can also use Partition Wizard bootable CD to mark Active then click on HD # to highlight it, from Disk tab select Rebuild MBR, Apply. How to Set Active/Inactive partition -Partition Wizard Video Help.Partition Wizard Rebuild MBR Video Help.

You can also force the installation to be seen and rebuild the MBR using the bootrec tool I gave you earlier from Steps 1-3 here: Error 0xc0000225 on boot

Actually it somehow started doing the repair afterall, and I did it 3 times as suggested, with the same outcome - bootmgr is missing.

I gave you the bootrec commands twice earlier. Before finally going to bed I realized that you were probably ignoring the step which would fix this which is why I posted it again. Why did you ignore it a second time?
