I recently Uninstalled my Ubuntu 9.10 partition from my 500gb IDE hard drive, and thought nothing of formatting the partition and setting it up as a new windows drive.
But, out of my own forgetfulness, i forgot that in rder to dual boot windows 7 with ubuntu, you Have to install the GRUB boot loader to be able to boot into both at will. this process wipes the original windows bootloader, and simply replaces it. Well, once I rebooted my pc, GRUB attempted to find a linux partition that was not there, and gave me this: "Error:unknown filesystem. Grub rescue>"
After some online digging, I found several articles that told me to use the "repair" feature on the windows 7 install disc. I did this, and the Disc was unable to find my windows 7 installation, although when i used the x:/ command prompt, i was able to easily see the C: drive,and the windows system. When i used the "repair startup" command, it ran through and told me that it was unable to fix the error, and that the root was that the Bootloader was missing or corrupt.
I think this is an error caused by what i think to be the real root dilemma, when my hard drive is physically set as the first boot device, the CD-rom drive is undetected by the BIOS, and vis versa, although when the CD-rom is set as the first, im able to boot into the windows 7 install CD. Im not sure if this is due to my BIOS being outdated, or what could cause this-but i believe its causing the cd to not see the drive as a boot device, or a win-7 installation.
Any help would be greatly appreciated, I have scoured these forums, and worked for hours on my own to no avail.
all suggestions are appreciated.
Thank you for reading this small book i seem to have typed.

Partition Wizard : Use the Bootable CD
Startup Repair - Run 3 Separate Times
I tried all of the solutions listed above, and again to no avail. I wiped the Drive which previously had grub on it with the bootable CD, and marked the windows 7 drive as active, and that did nothing for the repair tools to see the installation, although when i followed the link provided by Richc46, it showed that there was indeed a win 7 ultimate installation in place, alas when i ran the command "bootrec /rebuildbcd", it told me that "the requested system device cannot be found".I also ran the repair 3 times with reboots, but that only gave me the new root error "NoOsinstalled", which is very contradictory of it to say,I think -_____-
I forgot to mention before, but this might be of some help, when at the basic first screen of the windows 7 DVD,
I select "repair my computer", It proceeds to a progress bar window, which says on it "searching for windows installations", which then proceeds to a dialogue boxt stating "windows found problems with your computers startup options. Do you want to apply repairs and restart your computer?", and i then select "repair and restart", which promptly gives me an error dialogue box saying "failed to save startup options", which then proceeds to the section where you choose your windows installation, but in my case-it shows nothing at all.
Maybe that will help a diagnosis.
Thank you for your help, and time(:

Boot the Win7 DVD, press Shift F10 to open a Command Line, type:
bootrec.exe /fixmbr
bootrec.exe /fixboot
Close command line, enter Repair console to see if it now finds an installation to repair and will Startup Repair correctly.
What you are doing here is jump-starting the Repair by preceding it with bootrec commands which are automated in Win7 Startup Repair, but which may not be completing if it is malfunctioning due to OS corruption.
In the future, consider putting Linux distribs on a separate HD booted via BIOS so that GRUB is not necessary and Win7 isn't involved. Backup a Win7 image externally so that you never have to reinstall again.

Firstly - I have removed grub with the simple bootec.exe /fixmbr 100% of the time.
So from the top - make sure SATA native mode is disabled in your BIOS (device config)
Installation DVD - R - Command
bootrec.exe /fixmbr
bootrec.exe /fixboot
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd

attrib bcd -s -h -r

bootrec /RebuildBcd
I tried your suggestions, but There was no change in the repair error. It says that "startup repair cannot automatically repair this computer"
Would any other information be helpful in any way to solving this?
if so, please let me know, and I'll do my best to oblige.

And to solarwind, This is the error i got when i used the command listed:
"bcdedit /export C:\BCD_Backup"-The store export operation has failed. The requested system device cannot be found.
"bcdedit /export C:\BCD_Backup"-The store export operation has failed. The requested system device cannot be found.
This is quite a problem! 
Tak a look at the following: Windows 7 Suddenly Won’t Boot – Reboot and Select Proper Boot Device or Insert Boot Media in Selected Boot Device and Press Any Key � Repairing the Windows 7 Bootloader � Russ' Do It Yourself Home Workshop
Follow the instructions from where it says additional actions i.e DISKPARTand fingers crossed this solves it. Other than that I am totally out of ideas so could only recommend a complete reinstall.

All of those bootrec and bootsect commands are automated in Win7 Startup Repair, along with dozens of other tests and fixes which require it sometimes to be run up to 3 separate times with reboots to complete MBR repairs.
However, as implied earlier bootrec can sometimes jumpstart the Repair utility if no installation is found to begin with.
Some installations cannot be repaired, especially ones corrupted by GRUB. I will often go on running Startup Repair anyway and sometimes get it running but at some point you may want to cut your losses, wipe your HD and clean reinstall the OS's to separate drives if at all possible. If not: Where to install ubuntu in my system?
You can copy out your files if necessary using the DVD with this method: Copy & Paste - in Windows Recovery Console

I followed alot of the steps provided in the article, as his dilemma seems almost mirrorative of mine, and it now sees the OS, although it cannot repair it.
i ran setup three times again with reboots, and nothing-other than when booting now, instead of the old error message, i get "disk read error, ctrl alt del to continue"
that sounds bad guys.
sounds really bad.

c:\boot ........etc
assumes your boot folder's on c:
If you've got a 100MB active system reserved partition it's on there.
If that's the case you will need to temporarily assign it a letter & use that letter.
I'm a bit surprised you would need to resort to this.
you might want to run bcdedit and post a screenshot of the output.

Removing grub should be a quite painless operation. I have installed distro after distro and each time fixmbr has removed grub without issue. I then use diskwizard to remove and merge the partition into C:
Disk read error is just another symptom of a corrupt MBR (In your case)
Well as it now see's the OS and grub seems to have gone - now would be a good time to try bootrec.exe /fixmbr etc.

Well as it now see's the OS and grub seems to have gone - now would be a good time to try bootrec.exe /fixmbr etc.
I ran the bootrec.exe commands, with no change in the output, although when i did the startup repair again this time, the root error cause was as follows:
root cause found:
------------------------------------------------
Boot sector for disk partition is corrupt.
Repair action: Boot sector repair
Result: failed: Error code = 0x49c
-------------------------------------------------
Another thing that i tried doing was swaping the active drives around between the available partitions, and when i activated E:, and ran the command "Bootrec.exe /Rebuildbcd", it gave me the output That the boot sector of the disk might be corrupt, and as this is the partition where it tells me there is a windows installation (when running "bootrec.exe /Scanos"),i wonder if there is anything that could be done to repair the corrupted boot sector?

Post a disk management screen shot!
How would I do that?
I wouldnt know how to take a screenshot without being first booted into windows 0_0

Can you make a bootable flash or disc? You can then have a good look at what is going on with regards to partitions file system etc. There is also a utility to rebuild the MBR.
Have you Just one HDD on this machine? Was Windows always E:?
If you manage to run this then try to jot down the partition drive letters, file system etc. Also see if your 100MB partition is there.

Also with with command prompt (via Repair Disk)
>diskpart
>list volumes
.
.
>exit
will give you some info.
Maybe if we reassign the drive letter from E: back to C: we may have some success. I'll wait to see what partition wizard brings back.
I ran the partition wizard Boot cd, and all of the partitions are NTFS, and the drive letters don seem to show,as opposed to the drive labels?
But, when i did what MJF suggested, it came up like this:
Volume--ll---Letter----ll----Label----ll--Filesystem---ll----type----ll----size----ll----status
__________________________________________________________________________

----3-----------E-------------C------------NTFS---------partition-----235GB------Healthy
----4-----------F-------------SR-----------NTFS---------partition-----2933MB-----Healthy
Windows has always been C:, as far as i have known, and This is the only HDD i have ever used with this build.
And as stated above, the 100mb system reserved partition is there.
Also, when i tried to run the "rebuild BCD" option, under disk>rebuild MBR, the option itself is unusable for some reason?

meant to say list volume (not volumes)
The screen shot shows you can get quite a bit disk information from the command prompt.

Try doing what I did in my last post/screen shot
But your info shows you have the 100MB system reserved partition. This contains the boot folder and the boot manager. It also has a letter assigned which it shouldn't - see mine. Furthermore it's c:.
The last column (see mine) under info shows the the 100MB is system (active) & beneath it is boot.
(The MS terminology gets a bit of flak from some. "boot" is where the operating system lives and the boot loader winload.exe. "system" the boot manager and boot folder (with the BCD inside it))

Thank you very much for that,But how would i go about removing the letter from the Volume?
Partition wizard i assume?

Ok so command line operations on C: will target the system reserved partition. Command line operations on E: will target your OS (label C: when windows is running).
yes, from the tools section of the repair disk, or Shift F10.
So do you think that the Volume letter could be causing an error when trying to repair the startup?
At this point, it seems like my only option would be to try and get my files into an external HDD, and just format the entire drive?

Grub isn't stored in a partition. It's stored in the boot sector.. the very first sector of the HDD. Otherwise gregrocker has the correct advice. The fastest and easiest way to restore the windows bootloader after removing another bootloader is to boot to the windows 7 install disk, type shift+f10 to open a command prompt then type:
Bootrec /fixboot
Bootrec /fixmbr
Bootrec /rebuildbcd
It works every time.
Bootrec /fixboot
Bootrec /fixmbr
Bootrec /rebuildbcd
It works every time.
Number one priority is getting your files safe. After that we've got nothing to loose - agreed? Going back to scratch format, etc may be the pragmatic solution.
Do you need any assistance getting your files off the disk???

But I thought they said they had tried that.
If not do it of course.
Yes, we've tried it - I said in an earlier post it works 100% of the time for me also. /fixmbr is all that's needed.
I've been looking over various forums and when it gets to this stage I am yet to see anyone fix the issue without a reinstall.
chbell has a lot of patience, I'd have wiped it long ago

chbell10,
looked back over the posts
never mind the bcdedit /export step
just try running the 3 bootrec commands (again) mentioned above

Check again with Partition Wizard bootable CD that System Reserved is marked Active. If not, rightclick it to Modify>Set to Active.
Then boot the Win7 DVD Repair console to run Startup Repair up to 3 separate times with reboots.
If this fails, boot back into PW CD, rightclick SysReserved to Modify>Set to Inactive and then mark the Win7 partition Active to try the repairs again. This will eliminate possible corruption of SysReserved and write the MBR to Win7 partition itself.

If you want to make sure you can do it in the command line (refer my screenshot)
ATTEMPT 1:
To make sure it's active
For you in Diskpart:
>select volume 2
>active
-----------------------------------
ATTEMPT 2:
To make it inactive
>select volume 2
>inactive
& OS/Boot partition active
>select volume 3
>active
Then try the startup repair x3 as suggested by gregrocker.
If this all fails I would still do:
Bootrec /rebuildbcd
Then call it a day.
After I tried all of your solutions, the computer now knows that windows is on the hard drive,and attempts to boot it.
alas, this is the error message given :

2. Choose your language settings and click "next".
3.Click "repair your computer".

Did you ever run "bootrec /rebuildbcd"
I get that error message while active with volume 2.
And "bootrec /rebuildbcd" still comes back with the same error message from the very beginning of the issue, with "the requested system device cannot be found."
And the installation is still apparently found on E:, which i assume by it saying:
Total identified windows installations: 1
[ 1 ] E:\Windows
add installation to boot list? [y] /[n] /[a]:y
The requested system device cannot be found.

And the installation is still apparently found on E:, which i assume by it saying:
Total identified windows installations: 1
[ 1 ] E:\Windows
add installation to boot list? [y] /[n] /[a]:y
The requested system device cannot be found.
X:\sources>

I must leave for a while but in the meantime.
I assume
1) you have backed up your data
2) you are still trying to recover before a clean install
Do (1) because a clean install is looking the simplest way ahead.
But if you wish to continue...
Booting from the repair disk and entering command prompt you should see
X:\WINDOWS\SYSTEM32>
type
bcdedit
this will output the BCD store information on the active partition
1) Note the output
2) From your last post, you indicate that the 100MB partition is the only active partition. Then
X:\WINDOWS\SYSTEM32>bootrec /rebuildbcd
should work
If you've tried all the other suggestions and you've saved your data then is there a reason not to do a clean install?
Paragon Rescue Kit 10.0 (free) is useful for extracting your data if you haven't already done so.

Then boot the Win7 DVD Repair console to run Startup Repair up to 3 separate times with reboots.
If this fails, boot back into PW CD, rightclick SysReserved to Modify>Set to Inactive and then mark the Win7 partition Active to try the repairs again. This will eliminate possible corruption of SysReserved and write the MBR to Win7 partition itself.
When you ran Startup Repair with the System Reserved partition marked Active, were any other partitions marked active at the time?
When this failed, did you mark System Reserved partition Inactive and mark Win7 partition Active, then run Startup Repair up to 3 separate times with reboots?
I would use free Partition Wizard bootable CD for these operations so you have a graphical picture of what you are doing.
For both volumes, 2 and 3, I received the output :
The boot configuration data store could not be opened.
The requested system device could not be found.
---------------------------------------------------------------
But, when I open my command prompt with shift+F10 my Prefix is : "X:\sources>"
Not "X:\WINDOWS\SYSTEM32>"
And Greg-yes, I did all of the things you suggested in your post, but it seems like there was no change in the output of the Boot -__________-
I have backed up all of my data, Buuut it's not letting me access said backup data-so i figure i'll just purchase an external HDD, and boot into Ubuntu live, and do what I can with that.(If of course, it comes to that)

The X prompt from DVD is for its own tools on the DVD. You are not reaching into Win7 but working from Windows Recovery Environment.
You may have a corrupted boot sector that is irreparable. Best to wipe the HD to reinstall Win7. SSD / HDD : Optimize for Windows Reinstallation
Try to place Ubuntu on another HD so you can boot via BIOS and don't need to use GRUB since it corrupts Win7 a lot.
See if you can copy out your files to DVD or external using Win7 DVD: Copy & Paste - in Windows Recovery Console

Back.
I was actually working from the DVD Windows recovery environment (Winre) to emulate your situation, X prompt etc.... Neither here nor there now.
So I think the resolution is finally get your data & clean install.
I didn't understand your last comment with respect to data recovery.
"I have backed up all of my data, Buuut it's not letting me access said backup data-so i figure i'll just purchase an external HDD, and boot into Ubuntu live, and do what I can with that.(If of course, it comes to that) "
Getting your data should be straight forward with a bootable CD like Puppy linux or Paragon Rescue kit.

Boot off Ubuntu live cd: Terminal
sudo apt-get install lilo
sudo lilo -M /dev/sda mbr
Now attempt to boot into your windows partition
sudo apt-get install lilo
sudo lilo -M /dev/sda mbr
Now attempt to boot into your windows partition
