I multiboot, dos,2K,XP,7, 10, various linux and BSD flavors.
Each OS is on it's own Esata drive with no boot manager, so technically not exactly a 'multiboot'.
Problem is that immediately following a w10 update,(while only the w10 drive was connected) every time I connect the w10 drive to copy data etc, I get a blue screen on w7. It only happens on W7, and then OINLY with that w10 drive, the old not updated w10 loads fine.
This does not happen on any other OS, just when I am running W7 and turn on the updated w10 drive.
again, there was no change, other than bookmarks and a save game or two on the w7 drive and the W10 drive was the only one updated.
Before the w10 update, if I turned on the w10 drive while running w7, I would get a 'what do you want to do with drive x' message, now it's a bluescreen instantly.
When I reboot, leaving both the w7 and w10 drives installed, and use f12 to select the w7 drive to boot into W7, I have no problems. BUT if I turn the w10 drive off and boot to 7, I have the same problem when I turn the w10 drive on. (And yeah, I am one of the rare people who has OS2 disk set up for multiboot :) )
Any ideas on how to fix it?
