0xc0000225 error due to dual boot that morphed into 0xc0000098 error

This is my first post here. I have a HP laptop that came with Windows 7 Home Premium 64-bit preinstalled. Very long story short I tried to dual boot Windows with Fedora 15 and I definitely screwed up my partitioning. My first stop was LinuxQuestions.org which pointed me to Seven forums. I've been trying to get this fixed for about 2 weeks now. When I try to use the System Repair CD it doesn't show my Windows Os as being installed. When I just let the computer load from the hard disk itself I get the 0xc0000098 error.

On a whim I decided to put in an old System Rescue cd to see if I could see anything about the hard drive. Surprisingly it loaded and I was able to use GParted to look at the disk. The MBR is on sda1 which is unmounted. When I hard Fedora 15 installed I was able to mount the disk, but when I would restart the system it would unmount itself.

I tried to do a Clean OEM Reinstall through the use of a usb drive using the Windows 7 USB/DVD download tool. The iso file and the tool were downloaded from the links provided in the tutorial on a computer running Windows 7 Starter SP1 32bit. For some reason the download wouldn't work even with the bootsec.exe file downloaded and put in the correct folder. I used the Pendrive Linux Universal USB Installer to install the Windows 7 iso. For some reason even though I set the hard drive to boot from USB it won't boot. Is there any way possible I would be able to get my hard drive working again? I don't care if I'm able to get everything back on C drive or if I have to do a complete reinstall, I would be so thankful to have my computer working again.

Unplug all other HD's and peripherals, update your BIOS if it has an available update. If not reset BIOS to defaults Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS.

While in BIOS setup set SATA controller to AHCI mode to try install, IDE if that fails.

Set HD first to boot in BIOS setup.

Now trigger the USB flash installer by tapping the HP ESC or F9 one-time BIOS Boot Menu key at boot, select USB, Removable or HD to locate stick listing, boot stick. If you need to rescue any files proceed with Copy & Paste - in Windows Recovery Console . If not At first boot screen press Shift + F10 to open a Command Line, run Diskpart Clean Command.

Now follow the steps in Clean Reinstall - Factory OEM Windows 7 to get a perfect reinstall.

If problems persist post back the exact step where it fails and any verbatim error message.

Thank you so much for your help! The reinstall went perfect. Now I'm going to try dual booting again, but after I have everything properly backed up.

These are the best resources I've found on Dual Booting:
Dual boot Ubuntu-Win7
Dual Boot Ubuntu - EasyBCD - NeoSmart Technologies Wiki
Dual-Boot Windows 7 and Ubuntu in Perfect Harmony - windows 7 - Lifehacker

Thanks for the links. I was able to triple boot my computer with Windows 7, Fedora 15, and Ubuntu 12.04 and it works perfectly.

You're welcome.

Can you tell us exactly what worked best for you, and from which tutorials?

Well, I check out all the links, but none of them actually worked for me because my teacher told us we would also need Ubuntu installed on our computers. The link I used was this one which shows how to triple boot Windows 7, Fedora, and Ubuntu. I just followed along with the directions in the tutorial. Which helped the most were the clear pictures that illustrated each step.
