You don't have Fedora on there now?
I was going by what you posted above in post # 5
/dev/sda1 /boot 500mb
/dev/sda2 500000 mb lvm
/dev/sda3 500000 mb unlocalated for windows 7
If what you are saying now is how it is, then you may have over-written some of the Fedora partitions with Windows.
If that happened, then all you can do is reinstall Fedora.
Going by what you just said..
sda1 is your Windows system partition
sda2 is your Windows partition
Then you have sda3 which is the remainder of the drive except for sda4 wish is a linux swap partiton right at the end of the drive.
If this is how it is, then you would be better off removing sda3 and sda4...
Make a new sda3 which is 1GB for your linux boot
make a new sda4 which is a extended partition using the remainder of the drive
Now in that extended partition,
create sda5 which is your Fedora root partition, sda6 for your swap, and sda7 for /home
I would give sda5 about 50GB, 4GB for your swap and the remainder for /home
Then install Fedora 17, and at the partitioning screen, choose custom partitioning, and select the existing partitions just created.
sda3 as /boot formatted ext4
sda5 as / formatted ext4
sda6 as swap
sda7 as /home formatted ext4
And uncheck the box that says to use LVM.
Then tell the installer to install the bootloader to the boot sector of sda
going by what you just said, this appears to be your best option.
mess around with sda1 or sda2 or you can totally mess up your Windows install.
