New Windows 10 install cannot boot (no BCD)
Posted: Sat Jul 28, 2018 5:09 pm
Hi,
I decided that I wanted to add a Windows 10 instance to one of my desktop machines. That machine has a bunch of drives and had BING, and so I disconnected as many as I could, ending up with 4 drives:
Drive 0: 64GB SSD (yes it is that old) - had Window 7 and BING
Drive 1: 2TB drive - had several partitions, including 1 partition with a 2nd Windows 7 (this was supposed to be my backup Windows 7)
Drive 2: 2TB drive - Several partitions with data
Drive 3: 2TB drive - Several partitions with data
The BING was set for > 4 partitions enabled.
The MOBO is an ASUS desktop MB.
I resized one of the partitions on Drive 1 to make a 100GB area named "Win10Pro", then I made an NTFS partition (not formatted since BING doesn't format NTFS). My intention was to put the Windows 10 in this partition.
In BING I created a new boot item name "Win10Pro", and only had 1 partition, the "Win10Pro" one. I set the boot item for one-time SWAP.
Then, I did resume and selected the "Win10Pro" and booted to it. It gave me the error that nothing to boot, and I did Ctrl-Alt-Del.
The machine booted and I hit space to get it to boot the Win10 install CD.
I went through the install, selecting the 100GB partition. I noted that the other partitions were showing as unallocated space. That kind of worried me, but I went ahead with the install.
After the install finished, I think I reactivated BING, and when I started BING, it said there was some overlap error.
When I looked, it had the original Windows partition on Drive 0, but it also made a small (534MB?) partition and both the Windows and that small partition showed as "E".
I didn't know what else to do, so I deleted the small partition and then the error on the Drive 0 Windows partition no longer showed "E".
However, after that, if I boot to BING:
If I try to boot the Drive 0 Windows 7 partition - it says no BCD.
If I try to boot the Drive 1 Windows 10 partition - it says no BCD
If I try to boot the Drive 1 Windows 7 partition, that boots ok !!
So how can I fix the Drive 0 Windows 7 and the Drive 1 Windows 10?
Is there a way that I can manually copy the boot files from drive 1 Windows 7 to the drive 0 Windows 7?
What about the Windows 10? Can I copy the boot files from the install DVD to the Windows 10?
If it is possible, I would rather do that, as I worried if I try using recovery that might mess up the wrong partition...
Thanks,
Jim
