I have this major problem with my Windows XP Home. About two and a half years ago I tried upgrading to SP2, and I was never able to make it happen. I kept getting the blue screen of death. So, I just kept it at SP1, and the computer worked fine.
Recently I was put in a situation where SP2 was required. So, I have a copy of Windows XP Pro, with SP2, and I was going to upgrade. Well, in the process of doing this I got the following error, with the same blue screen of death:
"STOP: C0000221 Unknown Hard Error
I found that others had this same problem as well. I swapped out IDE cables and that didn't fix it.
I did have an Iomega drive installed at one time, but I uninstalled that months ago.
I then tried to use my WinXP Home edition disk to do a recovery. The CD wouldn't boot without the ntdll.dll.
Well, I had the recovery console installed already (did this months ago to help fight viruses), so I went to it. I copied the ntdll.dll from the WinXP CD to the windows\system32 file, as I saw recommended elsewhere. Well, now I can't even run WinXP Home, and the same ntdll.dll error persists.
Then I tried loading in safe mode.
Upon loading in safe mode the computer freezes right when it is loading the following:
So, it appears that the iomega driver is the problem. I uninstalled my iomega drive months ago, but apparently it didn’t remove the driver!
What can I do to fix this problem?
Thanks for any help.
