Hard drive won't boot on one specific computer
I have a Toshiba Satellite S55-A5294 laptop computer. It is running Windows 10. I had the drive encrypted using Jetico's BestCrypt full disk encryption.
Several weeks ago, I was using Windows, put the computer to sleep, and when I came back an hour later and woke it up, I got the "Preparing Automatic Repair" screen. This was followed by a message that automatic repair was unsuccessful. This problem has happened in the past. In the past, it was the result of a Windows update overwriting the BestCrypt bootloader (BestCrypt encrypts the system partition, so it has to have its own pre-environment password prompt, which can then pass to the mounted system). However, this time it wasn't the case.
As it turned out, I had a corrupted volume. With the excellent help of Jetico's technical support, I was able to recover my data. I pulled the hard drive out of the Toshiba computer, put it in a USB enclosure, and connected it to a Lenovo Thinkpad E530, also running Windows 10. In this configuration, I was able to decrypt the drive, and access my data.
I restarted my Lenovo and forgot to disconnect the Toshiba's hard drive. The Lenovo booted right up, into the Toshiba's desktop. I backed up my data, and, for good measure, made a disk image of the whole thing.
I pulled the drive out of the enclosure, and reconnected it to the Toshiba, from which it originally came. When I turn it on, however, I get a BSOD informing me that I have an error: INACCESSIBLE_BOOT_DEVICE, and the computer then automatically restarts. Upon restart, I receive either the same thing, or a "Preparing Automatic Repair" screen, which then tells me that my computer failed to boot, and suggests a restart. There is also the option for advanced troubleshooting. If I restart, I get locked into the same loop.
I am still able, however, to pull the drive out of that computer, and boot it up when it's attached to my other computer.
I tried connecting the drive to the Toshiba (the original computer from which it came) via the USB enclosure, and I still get the same errors. The Toshiba is able, however, to boot a Linux Live USB.
I know that the drive is bootable. And I know that the Toshiba is willing to boot. They just won't play together.
I ran chkdsk on the system volume, and found no errors. I tried using the Repair option on a Windows 10 installation USB, and didn't really get anywhere.
I can come up with no explanation for why the same disk would be bootable on one computer, and not bootable on the other.
Please help
