SUSE is in a separate partition
Yes it is a dual boot. I have SUSE in a separate partition. Under windows, I can see 3 partitions not recognised by windows. I guess this is where SUSE is installed one has 2.01 Gb, another one 19.86 and the last one 32.08 Gb.
I could probably simply suppress these partitions and reinstall completely a new distribution of Linux, but I want to be sure that this is harmless to my both windows partitions: C and D.
Thank you for your help.
