Because I want to use the OS3.1 environment without the .hdf method and I want to do this entirely using MorphOS, I came up with the following workaround for the "stuck at 12%" issue:

Obtain the following three archives:

e-uae-0.8.28.lha
e-uae-0.8.28-2.lha
E-UAE_0.8.29-WIP4.lha

OS3.1 needs to be installed by using version e-uae-0.8.28-2:
- Extract contents of 'e-uae-0.8.28.lha' and 'e-uae-0.8.28-2.lha' to the same directory
- Rename A1200.conf to .uaerc
- Place kick.rom in main directory (PROGDIR:)
- Create HardDisks/Workbench in PROGDIR:
- Add 'filesystem2=rw,DH0:System:HardDisks/Workbench,1' to .uaerc
- Startup emulation
- Insert 'amiga-os-310-install.adf' (Ctrl Alt F1) and start installation

During installation Installer complained about not having enough room for the contents of Fonts:

Back to the directory where E-UAE_0.8.29-WIP4.lha is extracted:
- Copy the Harddisks/Workbench folder from the old to the new location

To get the contents of Fonts: to your Workbench directory:

- Startup the emulation from the newer version of e-uae and open a Shell:

Code:
The specified command makes sure to copy all content except Disk.info

On a sidenote:

E-UAE creates '_UAEFSDB.___' files randomly inside the Workbench directory. To turn this off, add the following line to .uaerc

Code:

Getting additional files to your OS installation should be a lot easier now

Somehow the contents of Extras: also weren't copied over during installation...

Besides copying over the Fonts: also do this for Extras:

Insert 'amiga-os-310-extras.adf'
Code:

Hi, I'm new user MOS 3.10, When i try install the workbench 3.1 on the hard drive , the installer hangs at 12%. I set everything like in this guide http://www.morphos-storage.net/Documentation/Tutorials/E-UAE_installation_on_MorphOS.pdf , I wish to run WHDload. Is there any solution?

See comment #116.

I read the contents of comment #116, and I am fairly sure I'd screw all this up at some point in the process.

It's a shame that someone hasn't come up with a more automated installation routine.
I'd even be willing to pay for an easier, more integrated package of software (like Cloanto offers PC owners).
OS4 users have it a little easier (still not perfect), and it's frustrating that the easiest way to implement legacy emulation is with a PC, rather than under an NG OS.

Well, let's be honest, there are way easier and seemless ways to install...no, use WB3.1 through emulation. But if you insist on using adf's, sure, see #116.

it would be nice if someone created instructions for installing with E_UAE 1.0 (No GUI) it appears the .uaerc is no longer created but it is still looked for. I can't use the <CTRL> <ALT> shortcut <F12> with an Apple Keyboard connected to my G5 PowerPC (A1047).
And never get the requestor for Inserting an ADF image.

I've also found that <CTRL> <ALT> Q function rarely works.

Has anyone else had this problem?

Thanks
