Hi. This isn't really an installation issue as such, but I hope somebody could help me.
I have one hard disk, 1TB, which is divided like this:

(don't mind the labels on disks

)
Now, as you can see pclos is installed on sda7. I would like to get rid of two extra disks, sda5 and sda8 and was wondering what would be best way to do this without breaking existing pclos installation. The ideal situation for disk would be this: 800Gb Media (as it is now), 4Gb swap, 32Gb for pclos root (/) and rest for /home. Currently I have no separate partition for /home, just for /.
Options I've thought:
1) load some LiveCD, use gparted to 'delete' and 'resize' disks inside 'extended' block. I guess this might mess up my PCLinuxOS install pretty certainly, right?
2) Create snapshot of current machine with 'mylivecd', load it and delete the whole 'extended' block and create disks a'new, install LiveCD to new disk. Is this possible? Are all my current settings safe, (root passwords, hidden files etc.)? What might go wrong here?
3) Something else, what?
