Grub, Vista and F14 troubles

[Majara]

Hola!
I have received an ACER Aspire 7720 with Vista and I am trying to install F14. Really I installed it but, when restarting, there were some troubles:
1. Grub did not appeared.
2. Vista decided to loop on start and I could not boot it nor in fail safe mode.
So I recovered Vista with an recovery disk, but now I only can start in Vista from HD.

Now I am using a f14 Live CD in order to apply some solutions I have read in the tags but the partitions of Fedora do not appear with fdisk, although I can access them from Live.

The partitions are (as GParted describes them):
/dev/sda1 ntfs PQService diag 9.76 GiB
/dev/sda2 ntfs ACER boot 69.77 GiB
/dev/sda3 ext4 500 MiB
/dev/sda4 extended 69.03 GiB
/dev/sda5 linux/swap 2.00 GiB
/dev/sda6 ext4 67.03 GiBIn /dev/sda4 I had put "/boot" and in /dev/sda6 "/".

And with fdisk>
[root@localhost ~]# fdisk -l

Maybe the GRUB config file was just misconfigured. It happens often when Windows is involved. And it's usually easy to fix. But since you've already restored the Vista boot loader, you could re-install the GRUB boot loader in the Fedora boot partition (or re-install Fedora and choose the option that installs GRUB in the first sector of the Fedora boot partition), then use the free and popular utility known as EasyBCD to add a menu entry for Fedora to Vista's boot menu. Re-installing GRUB is a heavily documented subject, but help is available if needed. For EasyBCD, see its documentation.

If you insist on GRUB being your main boot loader, then re-install GRUB in the master boot record (or re-install Fedora). Then edit /boot/grub/grub.conf to fix whatever is wrong with it. For help with that, post the entire fdisk output again and the contents of /boot/grub/grub.conf.

P.S.: That fdisk ouput you posted doesn't exactly match up with your GParted layout, does it.

Hola!

Stoat:
I installed again F14 using "Install to hard drive" of Live CD and I put the Grub loader in the Fedora boot partition. The partitions were 500 MB for /boot ext4 (dev sda3), 2GB for swap (dev sda5) and the remainder for / also ext4 (dev sda6).

It restarted in Vista (without Grub screen) but as I don't manage too well this O.S. I restarted again with the Live CD and the partitions I see were:

I don't understand when the partitions are changed. I'll try to use EasyBCD after reinstalling F14, at restart.

¡Hola!

All the troubles were provocated by a malware installed in Vista. Kalpersky's TDSSKiller erased it.

Now I'm writing from Fedora 15 installed in the ACER 7720 computer. Problem solved.:D
