How do I fix this boot error on Windows XP (missing hal.dll and a missing partition)?

I use a partitioned disk drive, both with Windows XP Professional. I mainly use the H:\ drive. I got a virus and the H:\ drive got infected. I restarted, and learned that I was missing hal.dll. So, now I'm using my C:\ drive and I cannot access my H:\ drive. It simply says that it's a removable disk drive ( NTFS). However, I can still see the files I made on the H:\ drive and put on the C:\ drive, so they were connected at some point. I used the Windows XP Professional installation CD and got to the recovery console, and went through it all. I tried a command to expand the hal.dl file, but it seems that D:\ isn't my disk drive. I have tried every letter of the alphabet, and it still won't work. Also, the only disk drive I could select to restore was the C:\ drive. My H:\ drive wasn't there. I do not want to lose the data on the H:\ drive, but I want to be able to use it again. What happened to my H:\ drive? On the OS selection menu when I start the computer up, it's still there, but I just can't boot it up due to the missing hal.dll. I do not want to buy any CDs/programs and I do not need answers from advertisers of those CDs/programs. Otherwise, I'll take any suggestions.



Now... I checked out disk management. I have found my partition, but it is now an EISA configuration drive and it has no name. I can't do anything with it at all. Is there any way for me to access it?



One more thing: I do NOT need registry cleaners or dll files. I can't access the drive, and therefore I cannot place the files on it. I only need to learn how to access the drive.



If all else fails, then could anybody help me fix this annoying screen issue? On my H: drive, the screen was normal. I use a wide screen monitor, and it was perfectly proportioned. However, on the C: drive, everything on the screen is stretched very slightly. For example, this symbol here: 鈼? used to appear completely round to me. Now, it looks like an oval. The stretch isn't much, but it adds up and is somewhat annoying. Changing the screen resolution didn't help fix it.How do I fix this boot error on Windows XP (missing hal.dll and a missing partition)?
So...now, can you access any data on drive H:??

If you're still able to access the data on it. BACKUP the data soon.

Once you're sure you have all your data in drive H: then format it, recreate the partition then install XP on that if you want or stick with XP on C: drive.



About screen, try to take a look on additional display utilities that might be installed when you installed your display driver.

The utility usually comes with more advanced display configuration. Maybe you can fix your screen problem from there. ( Eg: intel onboard comes with additional tool to rotate screen, stretch it, etc )
