I couldn't find a separate thread for reporting ComboxFix bugs, so I'll post this here. If it belongs elsewhere, please move it.
Summary of the problem: ComboFix can not install Recovery Console (RC). The cause appears to be having a dual boot computer.
I had great difficulty using ComboFix on my system. I have a dual boot system with Windows XP SP3 one partition and Windows 8 on another partition. When booting in WinXP, the C: partition has XP and the E: partition has Win8. I was running ComboFix from the D: partition.
When I first ran ComboFix it said it need the Recovery Console. It tried to connect to the internet, but wasn't able to connect even though the connection was working. Disabling my firewall didn't help. I then tried installing RC manually using the command
from my WinXP installation disk. This didn't work as my disk is SP1. I then created a WinXP SP3 slipstreamed disk following the instructions at https://www.lancelhoff.com/how-to-slipstream-service-pack-3-into-windows-xp/
The link to SP3 at Microsoft no longer works. This site gives instructions on how to download SP3 from archive.org. https://www.computing.net/howtos/show/how-to-download-windows-xp-service-pack-3-sp3-after-april-8-2014/916.html
I was finally able to install RC, but ComboFix still gave the same error. It could not find RC or it was not the correct version. It would have helped if ComboFix could be more specific. Anyways, I finally found out how to manually give RC to ComboFix using the instructions at http://www.bleepingcomputer.com/combofix/how-to-use-combofix#manual_recovery
The Microsoft links to the Setup boot disk for WinXP SP2 are dead. I was able to download the software from http://www.jaytag.co.uk/windows-xp-recovery-console-kb310994-download/
I dragged the software into ComboFix and go the error message that RC was already installed! I then deleted RC using the instructions at https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/recovery_delete_console.mspx?mfr=true
Note that as my computer is dual boot, these files were on my E: partition. Dragging the disk software into ComboFix the next time finally resulted in no error messages. Of course, I wanted to delete RC again, but cmdcons couldn't be deleted, as described in the following link. http://www.techspot.com/community/topics/combofix-cannot-delete-cmdcons-afterwards.135243/
I found an alternate method to delete RC by just reinstalling RC from the WinXP SP3 disk. The files were then easy to delete. So we have several strange behaviour of ComboxFix.
1) Not being able to connect to the internet, probably because the file it was looking have been deleted.
2) Not finding RC, even though it had been installed.
3) Dragging setup disk software into ComboFix and saying that RC is already there.
To prevent these problems in the future:
1) ComboFix should not go to Microsoft to get the RC file, since the files have been deleted.
2) Properly recognise that RC has been installed on dual boot computers.
3) Get rid of the permissions that prevent cmdcons being deleted if ComboFix installs RC.Edit: Moved topic from Windows XP to the more appropriate forum. ~ Animal
