Windows 10 gets attacked with a disk repair in a multi-boot setup.
Before installing Win 10 preview onto an HDD I disconnect the other bootable drives lest they be molested by the Windows 10 install process. After installing the preview and updating everything I shutdown the PC and re-attach the other HDDs. My default boot drive has Windows 8.1 on it, and I get to the Preview using the BIOS boot menu. That's the setup I like. The problem is at some point while booting to Win 7 or win 8.1 the OS detects the drive with the Windows 10 Preview and starts a disk repair on it. Windows 10 never survives. Files get lost, system errors pop up, and the OS get left in an unrecoverable state. Not only that, the OS that launched the disk repair can corrupt itself leaving both OSes unbootable. What would cause this?
