Hi from France,

I need you to solve a bizarre problem.
The last year, I have partionned my HD of 1.2 GO in 500 MO and 538 MO.
Today, I need to retrieve my original HD of 1.2 GO.
So, I create a boot disk, I restart my PC, and I execute fdisk.
I delete the 2 logical drive in extended part.
When I want to delete the extended part, fdisk say me:
"Impossible, 2 logical drive in extended part."
When I return in menu "Delete extended part or logical" fdisk say me:
"No logical drive in extended part."
If I want to delete the primary dos part, I get:
"Impossible, there's an extended part with 2 logical drive".

What are you think of it ??

this is all done after rebooting to MS-DOS mode or to a boot disk.
