Disk Management let me delete partitions (D:), (E:) and (F:) (see Att.2 of the preceding posting). But it refused to delete the EFI partition. I used IFW to delete it, this time the copy function. It is easier to use than the restore function (which I used in my posting "Re: Converting BIBM-non recognized GPT disk to MBR with TBOS - Postby sigi » Mon Oct 05, 2015 6:53 pm") because the latter needs an image file, which I keep on an external drive, whereas the copy function can use any source partition available on the internal drive. The context menu of the selected destination partition then offers the delete function (see Att.1).

It was easy to convert the GPT disk to MBR using Disk Management in Win8 (on the SSD) (see Att.2). Thereafter the disk was again visible in BIBM and I could create the desired Extended Partition there (see Att.3). But when I first tried to do the conversion with IFW, I did not see how. Can you please tell me which steps would lead me to the respective (context) menu item or where I would find instructions in the IFW manual?
After receiving the answer to this one, I can consider this thread as having solved all my problems. I have attained the desired partitions and BIBM as the master of all of them.
A word of apology:
I have included many Attachments in my postings and described some actions in much detail. I did not want to be didactic but did it for my own benefit (later recollection) and perhaps for the benefit of a few readers that are not so familiar with partitioning problems as most of the members of this forum are.
