partition problem after dual booting fedora 17 with windows 7

nikosgevre · 10-26-2012, 08:29 AM

i had preinstalled windows 7 on my toshiba satelite p755-10k and then i installed fedora 17. after completing the installation and done the partition wright, i had 600GB HDD and gave fedora 50GB and the rest on windows 7, i have lost most of the free space of the 600GB HDD. windows 7 has 88,5GB and fedora has 50GB.
from the fedora system settings i can see that there is a free space of about 400+ GB but i can not find this space anywhere and i can't save files in it neither from fedora or windows.
please i need help!!
thank you.

Can you login in Linux and tell us the output of

Code:

df -h

and

Code:

fdisk -l

A disk can have a maximum of four Primary Partitions, of which only one can be 'Active' at any one time.

this is all i get after typing the codes:

In future use tags when posting output - it keeps the formatting and makes it readable for the rest of us.

Code:

$ df -h
Filesystem                         Size  Used Avail Use% Mounted on
rootfs                              50G  5.2G   45G  11% /

/dev/mapper/vg_nikosgevre-lv_home  431G  7.1G  402G   2% /home

Now maybe you can see where all the space went - your /home, which is for personal files (videos, songs, ...).
I'm guessing you did one of the "Install alongside current" type install, and Fedora decided this was the "best" setup.

Partitions/filesystems can be resized to whatever you want, but with LVM involved it gets awkward. When I install (Fedora includede) I always pre-allocate the partitions as I want them before I start.

I found a guide that may help;
http://www.linuxbsdos.com/2012/07/19...for-fedora-17/

Oh, and I recall something about Grub and the boot partition not being more than 500GB from the first sector...
