Paul G Posted Monday at 12:42 PM Share Posted Monday at 12:42 PM I have two swapable "C" drives in my computer. One for my business, (win 7) and one for music, (win 10). Lately both of them are taking a really long time to boot, up to 30 minutes. Any thoughts about what may be causing this? TIA Link to comment Share on other sites More sharing options...
Amberwolf Posted Monday at 07:10 PM Share Posted Monday at 07:10 PM What happened just before this started? Was there an install? Update? Etc? Was there an uninstall? Was there a change in environmental conditions? Weather? Power? Hardware? Cabling? Link to comment Share on other sites More sharing options...

Are you physically swapping these drives or are they permanently connected? And how are you choosing which OS/drive to run as C? If they are two physical drives connected, I would start with checking your UEFI/BIOS, since that is where the C drive is designated. Two physical drives both with an OS on them can confuse the crap out of that, so it may be trying to determine which drive actually has the "OS" on it. A little more insight into your situation would help us understand better. Link to comment Share on other sites More sharing options...

I had kept them mostly disconnected as I worked through the new installs but lately hooked them all up. I tried disconnecting them again and that seems to have narrowed down the issue. I'll now go through them one at a time and hopefully find the culprit. Thanks for the help. 1 Link to comment Share on other sites More sharing options...

When I was installing the other drives, (see above), I would open the BIOS to reset the "C" drive. but typically the BIOS follows the swapped drive as the 'OS' drive. Thanks for your reply. 1 Link to comment Share on other sites More sharing options...
mettelus Posted Wednesday at 06:04 AM Share Posted Wednesday at 06:04 AM Something to check would be the Disk Management for each OS after it loads (ironically, "Create and format hard disk partitions" in the search bar is how to call it up). Check the bottom portion of that and see if the drive assignments jive between the OS drives when swapped. That is always something to check when swapping/installing new drives, especially if you have junctions in use. Windows gets rather weird and decides drives assignments on its own sometimes if you don't manually tell it how to function in that window.
