Cant Format E Drive Old copy of windows seems stuck on it

You need to change your boot options to not show you the list, right click computer and choose properties then click advanced and follow my picture. If you want to remove the second entry it is is in your boot config and can be done with msconfig but that is more technical so i'll wait for what you want to do. Your disk is probably something different, can you post a pic of your disk management like mine.

EDIT: Added a pic of the tab in msconfig that would show you what it wants to boot.

Hello pitbull69. Welcome to the forum.

A screenshot of your Disk Management window, expanded so we can read everything, would be helpful.

Thanks guys heres my disk Management, while I read have a look at what else you mention me trying..

Also attaching my boot options, they look the same as above picture.

Is disk 0 the one your trying to erase?

EDIT: saw you edited your post, if you uncheck the time to display area then it won't ask you to pick one unless something goes wrong at boot.

Disk Z im trying to erase, I renamed it in the silly hope it would help..

I have now removed the 2nd boot install, so 1 down, and thankj you very much for the advice. I was hoping if that went it would allow me to format, but same thing when I ask it to format,

yeah that's because it is a system partition you must have some underlying files that it is using on that partition or it just sees it has that type of structure. Did that drive come out of another pc? Where did msconfig say your second boot entry was supposed to be did it say Z?

Okay do this for us, if you remove that physical disk( Disk 1) when the pc is off will it start and boot into windows or does it not go anywhere without that disk? It sounds like your BCD still thinks the old windows is installed on there as OS 2. Do you have a windows.old folder in that drive?
