Win7 swapped my Drive letters over

  FearlessFred 23:27 04 Nov 2009

I've got 2 hard drives. Hitherto C was the systems one with all the Programme files etc and D was all my Documents Music, Pictures, technical Drawings etc

I tried to install Win 7 Pro 64 bit and after 2 failed Upgrades (from Vista Business 64 bit) did a clean install but aftewr a day kept getting Blue Screens, despite running Win7 Advisor

Took PC to local techie and when I got it back found D was all my System Files and C was all My Docs etc.

Did an Easy Transfer (saved on an External HDD) from before I tried upgrading.

Now every time I put a new programme on it goes - by default of course - to C/Program Files.

Apart from shooting the techie, what can I do?

This is most unsatisfactory because it appears you have bootmgr on drive C and Windows 7 on drive D.

However, you can change a registry key to point to drive D for future program installations:
Click the Windows Orb (Start), type regedit, press Enter and navigate to registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion. In the right pane, right-click ProgramFilesDir and Modify it to D:\Program Files which will put all newly installed programs on the D drive.

Well it's all gone down now. Won't boot up - I made a Repair Disc and that doesn't help. All System Restore points gone.

Think will now format Drive C, Clean Install and recover what Docs I can to Drive D (prob most) from my external drive backup.

Suppose I'd better format D too?

Thanks anyway.

I wonder what could've caused it. What a mess and W.O.T.

Changing that registry key would not have caused the problems you have cited.

As I said initially, the setup that you were given by your local technician was 'most unsatisfactory'.

I don't know what W.O.T. means!

Yes, thanks.

And W.O.T = Waste Of Time!
