Hello. I'm new to the forums, though I've read some posts here before. Anyway, I'll get straight to the meat. I have in my possession a Gateway laptop running Windows 7 Home Premium. The person who owns this laptop ran TDSSKILLER, and deleted the TDL file system it detected (DR0). Now, naturally, it will not boot into Windows. To be more specific about the OS, it is Windows 7 Home Premium OA Acer Group. I do not have the original OS media. What can I do to get the system back up and running? Thanks in advance.

If it is a commercial system like Acer it should have a recovery partition that you can restore the system to its factory build image.

Good luck.

And how do I get to the recovery partition? Alt+F10 doesn't work. I can get into BIOS (F2), and I change boot devices (f12), but nothing beyond that. I get a blank, blinking cursor screen of doom.

I was trying to get by without ordering anything. So, I used Hiren's boot cd to boot to the Windows partition, which then gave a stop error. This allowed it to at least boot with the "Startup Recovery" option (rather than just a blinking cursor and black screen). Startup Recovery failed, but I was able to get the the command prompt and dump the boot record and rebuild it:


  • bcdedit /export C:\BCD_Backup
  • c:
  • cd boot
  • attrib bcd -s -h -r
  • ren c:\boot\bcd bcd.old
  • bootrec /RebuildBcd

I can now boot into Windows again.

Thanks.
