Good day,
@zantak, I did not pay attention last time. You have already a multiboot box. If you have EFI, most likely, enabled boot for Windows, and also Linux running on EFI mode, then you should try the UEFI bootable image.
What I have used is the plain Anyboot ISO, which boots in MBR mode as this box is 100% Haiku only, so no need to worry about UEFI in my case.
Probably it will work with the UEFI image and you can boot your box though it needs some fiddling as pointed out in the UEFI topic. I have tried an old UEFI iso which never worked for me, maybe because the process I followed wasn’t the right one.
Whatsoever, @kallisti5 reported that the new R1Beta1 release may or may not work on some devices, Ryzen included, so it is a matter of patience and trial/error. You should be aware, at least in my case, to have the keyboard/mouse plugged into a USB 2.0 port, even if you set your BIOS for usb compatibility… At least in my case is needed.
After I got Haiku installed (hrev52295) I haven’t tried to boot with other revs, be them nightly nor beta. Just changed the branch from beta to rolling/master, and the box keeps working fine with the VESA driver, and the memory limit.
In your case, I would try the UEFI ISO following the recommendations stated in
or newer images if available. And remember to turn off Secure Boot, and all the BIOS stuff.
Regards,
