I will start with…why does Microsoft make everything so infuriatingly hard to do? okay got that off my chest. I bought a new Dell xps 9860 pre installed with windows 11. After incredible wrangling just to get my video working I have moved on to getting widows 10 as my preferred OS. I can not use windows 11 for my needs as it would require me spending over $10,000 for new software. Don’t ask, just trust me. So I created a new partition on the drive that has windows 11 and named It windows 10. I next cloned my entire windows 10 drive onto that new partition. If I had to reinstall 10 it would take a month or two to reinstall my programs..don’t ask. It all about digital audio work stations. Sooooo, I went into the bios and there, of course is no boot order option., oh except the new EUFI windows 11 . How in the good grapes of god do I get set my windows ten partition as the boot partition? Pleas oh please enlighten me. I am now going to go get some wine and say many bad words with the name Microsoft attached to them. Thank you
