[SOLVED] Problems after Linux installation.

I installed Fedora Core 9 on my computer. Yay for me.

However, after I installed it to my secondary Maxtor drive, GRUB happened to disagree with my Windows boot drive. Originally, every time I tried to boot into my Windows drive, after loading up the DMI Pool data, it would tell me "GRUB Hard Drive Error".

Now, I cannot boot into Windows on my primary. Whenever I try to boot directly into my Linux drive, it always says "Error Loading Operating System". Whenever I boot to my Windows drive, it boots into Fedora, although it is on the other drive. This is due to my boot order on the two drives: Windows first, then Linux. The computer does not show anything regarding the Windows drive, but simply follows the boot order and goes straight to Fedora. This is the only way I can boot into Fedora, which I am running now.

I installed Fedora from a Live CD which I burned using a downloaded ISO from the Fedora site, and Nero Express 6. Whenever I try using the "Boot to Local Drive" option when booting from the disc, it only tells me "Press a key to restart", and reboots.

I cannot access my Windows volume (obviously) from Linux, because of its NTFS file system. I read on another forum from people with similar problems that this is a GRUB issue with the Windows drive.

Windows is on a Western Digital 200 GB drive, and Linux is on a 20 GB Maxtor drive (the only thing I had available to hold it). I would like to boot into Windows, but if that is not possible, I would like to be able to access the drive with Linux and install Wine. Whenever I try to install Wine, the install file won't open. I have to use Terminal to open it, right?

My system is fairly good (it could run the latest games this time last year). Its weakest point is the graphics card.

It has an Athlon 64 X2 @ 2.66 GHz, 4GB of DDR2 SDRAM @ 800 MHz, the aforementioned hard drives, a PNY nVidia GeForce 8500 GT graphics card w/512 MB video memory, a SoundBlaster X-Fi 128-bit sound card, and an ECS C51GM-M motherboard.

I have tried resetting the Bios to defaults, and it didn't work. I tried a Super Grub Disc, but it wouldn't boot.

Help? It's taken me a year to install all the software, updates, and customization that Windows XP has on my computer. I REALLY don't want to lose it all.
