Okay . . a little low on RAM for Gloria Main or KDE, so I would suggest you try the Xfce Edition, it'll be much faster. I have it on my laptop
, and just love it !
Primary - swap partition - 1024 Mb.
Primary - / partition - 12000 Mb.
Extended - /home partition - 10000 Mb. (lotsa room for apps & games)
Extended - /data partition - as much as you want up to the rest of the disk. (downloads, backups, etc.)
You have enough room that you could even leave 40 Gb. unused / free , room to try another OS/Distro for dual-boot in the future ?
Please note that this is just my opinion . . It's really up to you !
One of the joys of Linux, if you find you don't like your setup, or you
, you can always start over, and be back up and running in half an hour !
good luck, Richy
