I'm running Windows XP SP 2 Professional on my computer and using two hard drives: an old one with a capacity of 18.6 GB and a newer one, an 80 GB Maxtor.
I wanted to erase every bit of information on my old HDD to use it as 'deposit box' from now on. Since I had Windows XP OS running on it before buying my new hardware, I decided the correct choice would be booting from my XP SP 2 Boot CD and deleting the partition D (that would be my old HDD).
After deleting I made a BIG mistake (and I feel ashamed because I'm pretending I know stuff related to Windows OS and helped some of my friends overcome some serious troubles). Wanting to format the old HDD to NTFS, instead of booting up and formatting it from My Computer and so on... I chose Install Windows XP on the old HDD knowing it would automatically ask for formatting it before install. I assumed I could cancel installation at any time after Windows Setup would have formatted it, although I couldn't remember for sure there would be an option to stop installation... Obviously, Windows Setup continued its job, even rebooted and started installing XP for real... And I don't know why, now I can't find any excuse, but I made the biggest mistake: pressed RESET button...
From that time I get a dual boot screen with two identical options: Microsoft Windows XP Pro. One of them would boot normally, one of them tells me something about "hal.dll missing or corrupt" and machine hangs...
Here is what I've done so far: format the old HDD again with XP SP 2 Boot CD, then format it NTFS under Windows Explorer (like I should have done the first time). So now partition D is empty and, it seems, working fine. Then I did a Repair on my good and functioning XP SP 2 OS (the only installation my Boot CD Setup shows as existing).
The dual boot screen is still there... and I'm desperate to get rid of it... I've learned my lesson, now please help me overcome this!
