W95 Install w/ W3.11

I have Boot Manager, and 3.11 on c: drive; I have 3.11 mirror
on d: drive, and an OEM W95 floppy set. When I try to install W95, I get
the existing os error. Suggestions have been to wipe 3.11 off, or hide it, while
installing. Is that the only way? Seems like an incredibly stupid system and a real
opportunity to spend time reinstalling everything that you cannot boot.

I have Boot Manager with Partition Magic. I get the warning about overwriting Boot Manager, and I know that *if* W95 successfully installs, I can get back into Boot Manager and make it active. The problem I have is different. For example, if I "hide" 3.11 on drive c:, and attempt an install of W95 from the bare partition, i.e., even no formatting, the disk will start with a format and then move into the setup disk installation. During installation I am given a warning that Boot Manager will be overwritten, and I chose to proceed. Later, at the end of disk 2, I get the error message that there is already an operating system installed, and that I must use the upgrade disk.
I have also read the Partition Magic help, and asked for clarification, and essentially have been told that I must hide everything, even the mirror on d:
If I do this, and the install is unsuccessful, then I have to use a boot floppy. When I do that, I can no longer use Boot Manager, because it has been overwritten, and using fdisk shows that the hidden partitions are non-DOS. My fear then is that even if I try, with fdisk, to make this partitions (which really are the hidden 3.11 partitions) active, I won't be able to boot.
I thought perhaps I should move the 3.11 partition, to give
W95 cylinder 0 to start install, but I really want not to have to reinstall DOS and 3.11 if there is a disaster.

I think you mean you get an error about "boot manager" being installed there. No problem. You can install WIN95 as "replacement" to the 3.11 (using same directory) or as additional (using a different directory, you will be able to return to DOS using F4 after "windows 95 starting" message.)After you finish with Windows 95, you reinstall Boot Manager. One wway is to boot using OS/2 boot diskette, continue "installing" until "fdisk" is there, reinstall BM and EXIT (f3) the installation. If you have BM from different source than OS/2, use tthe proper documentation for that. For example, you can get a BM from Partition Magic.

I understand.
You try to use 2 partitions and 3 operating systems. Cannot work the way you want it.
Windows 95 and 3.11 can coexist on the same partition WITHOUT using BM. Works really fine (even the OEM version). Another solution is to create ONE MORE partition - disk e:, and install windows 95 there, while c: and d: are hidden.
Also, you can create an additional partition (even a fourth one) and install PM there, so it will be available and in working condition when you boot from a floppy.
Otherwise, I still cannot understand what is the problem.
Do you try to work with fat32? Don't do it if you want each os access each partition.
BTW, from my experience, osr2 does not force me to format disks, may be you have a different version.
