I don't, both Windows RE and Sweeper couldn't detect or let me access whether browsing when I selected load drivers or just trying in cmd to open the drive letter. Always something about being corrupted or unreadable.
Can you still run chkdsk /r on d:?

Yeah, I was able to do that yesterday.

Okay, so it was the d: drive that was having issues during the recovery process of chkdsk. I figured as much, but wanted to make sure. When you opened the drive using the Linux DVD, did it show up as NTFS?

My theory is that Windows is seeing the drive as RAW, which should have been fixed by TestDisk, but apparently was not. There was one method I stumbled across that might fix the problem, but I will need to do some further research. I'll do that while you're trying the backup sectors partition option.

Yeah, it was NTFS in Ubuntu.

EDIT: BTW, I remember that the time I was using the PC before it stopped booting properly, was when I turned on my external WD Mybook drive. I leave it connected to power and USB but don't usually unlock it for use because I had problems with it acting extremely slow in the past. So I did that time just to delete some stuff to free space., then safely removed and unplugged it. The next time I booted, it failed and at first I thought it was because BIOS was trying to boot from my secondary drive, which didn't have Windows. However I corrected the order and it still didn't really help me. But the drive letters changed a few times when I unplugged and replugged drives so I think today the drive letter is E:

I was mistaken. Testdisk will not fix a RAW file system as Testdisk only fixes partition errors. You may as well stop the Testdisk scan. I'm trying to find a viable solution...

See post #14. Also, make sure you are very careful with spelling and carry out the steps exactly as written. Do not proceed to the following step until you know the previous step actually did something.

Okay I just tried the TestDisk thing this time setting the "backup" one at 600 GB as Primary. It said:

Boot sector
Status: OK

Backup Boot sector
Status: OK

Sectors are not identical.

A valid NTFS boot sector must be present in order to access any data; even if the partition is not bootable.

My guess is that the backup sector is your entire drive, so it would overwrite the boot partition, hence the error you receive. Leave your partition table intact and go through the tutorial I just posted. I am thinking you do not have a partition issue but a file system issue.

I tried something like this at first but it didn't work. However I will follow the steps exactly anyway.

Under System Recovery options, it still shows Windows 7 with a Partition Size as "0 mb", location E: local disk.

I followed the steps until diskpart> list volume. It turns out that the E: drive is indeed "RAW", and is 558 GB (total size of drive). The other secondary drive shows the letters of the partitions to be D: and F:, both of which are NTFS. Fortunately, everything says Status is healthy.

Okay I finished the steps, and it says "successfully updated NTFS filesystem bootcode. (under a line that said C: (\\?\Volume...)) and "successfully updated disk bootcode under "device\harddisk". Then "Bootcode was successfully updated on all targeted volumes". Going to try to restart and boot now.
