Remember if you follow this you could lose your current linux installation if things go wrong.
I do think that apart from the possible colour issue my new installers for Debian and Lubuntu are better than what you have now.
Only 1 partition. 2 GB SFS/00. This is works as a boot or emergency boot partition for Linux.
The 20 GB should not be partitioned but left as free space preferably at the end of your hard drive.
If you want to keep your original linux installation and it is already the last 2 or 3 partitions on the hard drive
then leave the free space in front of this
If you dont have any free space on your hard drive then you will need to create some by deleting or resizing an existing partition.
If you do this you will need to back up these partitions before you delete or resize .
To be safe you should also back up all the other partitions in case something goes wrong.

Once you make any changes to the partitions on your hard drive you will change the partition numbers so the Linux bootstrap will
no longer point to the correct root partition. you will not be able to correct it on the linux side because you wont be able to boot linux.
This is where the emergency boot partition comes in. Before you do any partition changes you need to copy 2 files from the linux
/boot partition to a fat32 formatted thumb drive. Assuming that you are using parthenope as your bootloader these files are
uImage and menu.lst.Once you have created the 2 Gb SFS/00 bootable partition under AmigaOS 4.1 copy the menu.lst file to it.Then make a directory named boot on that partition. copy the uImage file to it.
Next you will have to work out the partition number of your Linux using media toolbox. Select Edit partitions and file systems for your harddrive. Locate the Linux root partition it should be Named dxh Filesystem EXT\03 .
Count the partitions from the start starting from 1. dont count any unpartitioned space in front of this partition.
so if it is partition 11 the your linux root partion is dev/sda11 .
Once you have worked out the partition number of your linux root partition edit the menu.lst file on the SFS/00 linux boot partition .
all you need to change for the old kernel is the sdaXX part to point to your linux root partition.
For my 3.13.0 kernels you need to add the radeon.dpm=0.
lines with # in front are disabled. Once you get linux booting this way you can adjust the menu.lst on the linux LNX\00 /boot partition to
point to the correct Linux root partition and use this to boot by disabling the emergency boot menu on the SFS/00 partition by adding
the # to the beginning of the lines in the menu.lst file on that partition.
You can use this method to install multiple versions of linux.

@ Spectre660

Thank you for the very detailed reply, I understand the process now and feel confident enough to now try it next week.

Best Regards
