- What's your OS?
- How do you do a "routine reformatting"?
- At what point did you get that message?
- How many partitions did you have on how many hard disks?
Partmgr.sys is a file in the windows\system32 folder. So Windows must have been quite a way installed to give this message.
I checked checked one google link and found somebody with an install of Windows XP giving "the partmgr.sys error" (but he didn't tell details). One of the answers told that this could be solved by a BIOS update. It's rather strange.
It's best to NOT give friends administrator access to your PC and to NEVER reformat.
Heya. So, I wanted to do a routine reformatting of my computer... You know, to thoroughly wipe all of the balls stuff that friends of mine have successfully poisoned it with. Everything was going fine, I was doing everything like normal, until I got this: "the file partmgr.sys is corrupt." I spoke to a tech guy and he said my partitions were screwed up... And thusly ended the phone call.
