    Hello,

    I have Windows 7 on a bootcamp partition running with Parallels. I plan to upgrade to Windows 10. Will I need to reinstall the bootcamp partition with new Windows drivers for Windows 10 or can I just boot directly into Windows 7 and upgrade to Windows 10 from there?

    Thanks.

    That is correct. You won't need to reinstall Bootcamp.

    You should reinstall Boot Camp because if you upgrade it directly, Windows 10 will still run in BIOS-CSM mode and that won't do.

    In order to take advantage of UEFI, you'll have to remove Boot Camp and re-create it.
