- The reason that the NT Beta will not install with Boot Manager is NOT
- because Microsoft hates IBM, or because Microsoft wants to make your life
- miserable, or any other shadowy Microsoft conspiracy. The reason is
- that Boot Manager plays games with the partition table. Notably, the
- partition that NTLDR gets started from is no longer marked ACTIVE.
- Instead, the Boot Manager partition is marked ACTIVE. Whether or not
- you think IBM has broken the "rules" of the MBR and partition table,
- the fact is that without a lot of amazing gymnastics (like Doug Hamilton
- has outlined elsewhere) you cannot get Boot Manager and NTLDR to agree
- on what partition should be marked ACTIVE.
-
- Since installation of NT over Boot Manager will likely result in either
- an unbootable NT or an unbootable OS/2, Windows NT Setup does its best
- to prevent this. You may consider this "sneaky" or "underhanded" if
- you like. But the truth is that this configuration is not supported
- for a REASON that has nothing to do with marketing.
