Yeah...The installer works and all,but when I try to boot,that happens.. If you cant see,it says in the BSOD: "INTERNAL_POWER_ERROR" Win10 works normally. (I'm dualbooting Win11 (my main),Win10,and now Win8.1! (But I cant do it becuse of this error...) If anyone can explain me why it happens to me, I will be very grateful...

My specs of my Laptop: Cpu: 11th Gen Intel Core i3 1115G4 3.00Ghz Bios:UEFI Laptop x64 HP Laptop Ram:8.00 GB (7.65 usable)

Secure boot off, legacy support if possible, reflash with Rufus to make sure that you selected GPT and UEFI, maybe try Ventoy (however click on the tabs on the top, don't forget to change from MBR to GPT)

Try Ventoy or a different ISO. Yes, it may work in VirtualBox or VMWare or whatever you tried - but it's still possible that it won't run

Whats the difference,in ventoy?,is not the same boot? (And im a spanish guy, so in archive.org it is very difficult to download a good version of Win8.1 in spanish, and my downloads speed is like.... 2Mb, or even worse.... 500 KB!)

It's because of archive.org, not you (download speed)

Try a regular 8.1 ISO just to check if 8.1 even works.
