Resolved Unable to boot Windows after PC repairs

I left the machine in sleep mode for approx 2 hours and when I returned it had shut down.
Tried to restart the machine but it was completely dead and I couldn't even get to the BIOS.
I assumed that the mother board had hit a problem so ordered a new one and decided to get a newer
model of the processor, an AMD FX6100.
The installation was straightforward with no problems but now I am unable to boot at all. The bios
has found all the components correctly but says that there is no OS installed when I try a boot to the
SSD which has Windows 10 installed.

1st Repair attempt.
Boot from my Acronis repair disk, and ran the three command prompts. All three reported completion but
an attempted reboot did not work, no OS found.

2nd Repair attempt.
Boot from an Acronis System disk made from the installed OS.
Got a windows logo and the running indicator and had a long wait for the Acronis screen where I chose
the French keyboard and System Restore. SR ran, finalised, but had not restored, unspecified error.
Error: 0x80070091.

3rd Repair attempt.
Booted from an old Windows installation dvd. Managed to select the keyboard but then got a BSOD with
Stops: 0x0000007B, 0xF78DA63C, 0x00000034. Missing File: \boot\bcd missing.

I would be grateful for any help with this problem and any MS web address where I could find the
answers to the stop errors. It used to be easy but I can't find them now.

 

Bonjour Evan,

As I said, I had just selected the French keyboard when I got the BSOD.
It is difficult to protect against a failure like this one, the only easy way that I can think of would be to have a duplicate OS already loaded onto a replacement SSD. I had a Windows system imagine on another installed hard disk, and a True Image clone on a usb plugged hard disk kept aside. I've had several major problems since starting on Windows in about '98 on various machines but nothing like this one!
One thing that I will have to remember is that I should always have a Windows DVD to hand, which I don't at the moment and haven't had since Vista. My own fault for depending on downloaded ISO files which unfortunately I have stored on my unusable machine!
I have now downloaded the ISO for Windows 10 to reinstall and I have to hope that the key for Windows 7 which was upgraded will work.

No. I have no other peripherals plugged in and unfortunately no English keyboard was available.
1. I did download the Windows ISO and burned a DVD ok. The first problem I had suspected would happen did - the Windows key
from the 7 upgrade to 10 wasn't accepted as genuine. As the SSD had already reported a missing file \boot\bcd I decided to re-install Windows over the old one anyway and fix the key problem when it was up and running.
2. Pressed the 'Install Now' button and Windows reported - 'We couldn't create a new partition or locate an existing one. For further
info see the Setup Log file'. Obviously the SSD has suffered, probably during the mother board failure. I have a new one on order.

The new SSD was recognised and Windows was installed OK. Cursed now with a very slow BIOS boot and OS startup which I am investigating.

 

Try Run > msconfig > Boot > Timeout to zero.
It will take a few Starts in W10 but it does speed up as the OS settles down.
I generally have between 15 to 20 seconds from boot to Desktop.
