Dual Boot win11 / win10

[Gazzamius]

Hi. my user name is Gaz, just joined this forum. hope you guys are all good. I have a question. I use Windows 11 as my main operating system, (located on C Drive) I have 3 M2 SSD Drives and would like to use my D: Drive as a separate Windows 10 system drive. is it a straightforward install using EASYBCD software from my D Drive using a Win10 .iso file. just asking before I go ahead and do something I might regret later. Thanks for any assistance. stay safe all. regards Gaz
