Help Multiboot final edition 4.1 53.71 classic

Hi,
I read this:
https://amigaworld.net//modules/featur ... ?op=r&cat_id=4&rev_id=172

I was wondering if this guide was applicable to the final edition classic version 53.71
using winuae to create different multiboot startup-sequences

Thanks for every suggestion.
Thanks again for every help.

This works in UBoot machines, like SAM 440, AmigaOne 500, etc, I don't know if WINUAE can emulate this machines.

Hi RIBDEVIL,
thanks for the reply, I read UBoot in the startup of the lnk posted
I thought there might be some variant for amiga FE1 classic systems.
Thank you very much for your reply.

I have an Amiga1200 with PPC and AOS 4.1FE and AOS 3.9 in dual boot.. is this what you want to achieve?

Hi nubechecorre,
Exactly
Thanks, what should I do there is a guide for this?
Thanks again.

To dualboot my A4000 i have one partition for each install, the one with os3.9 is my default os so i have it set with the highest boot priority.

My OS4.1 partition has a lower boot priority and i'm using a bootdevice kickstart module in my kicklayot with my system os4.1 partition defined as boot partition so os4.1 will default to this partition when loaded.
(read about bootdevide in sys:documentation/kickstart/bootmenu.doc

On cold boot i just let it boot into os3.9 if that is what i want and if i want to boot into os4.1 i do it from early startup, when the 4.1 kickstart is loaded it will boot from the correct partition until i do a cold reboot.

There is other ways to solve this but this, you could for example download a tool called "ChangeBootPri" and play with it.
I have it on some amiga and it's quite nice, i execute it in s-s to make the last partition i booted from the one with the highest priority.

In WinUAE a simpler solution would be to just create separate configs for each OS version you want to have. No need to mess with multiboot setup then.

@all
Thank you, for the answers.
I asked, this type of solution because I have a particular configuration to use winuae.
In practice use win7 64bit where I use only winuae that mounts a real partition with the filesystem SFS / 02 marked with "x76" hidden, as was done with "amithlon"
At the moment I use a batch file to launch the other amigaOS
But the solution that suggested me "nubechecorre" would be excellent
I hope it is achievable.
here a little video to be more precise:

Thanks again for the suggestions and advice are very valuable.
